How does climate change impact the Forests of Sumatra?

Answers

The destruction of Sumatra's natural forests is accelerating global climate change and pushing endangered species closer to extinction, a new report warned today.

A study from WWF claims that converting the forests and peat swamps of just one Sumatran province into plantations for pulpwood and palm oil is generating more annual greenhouse gas emissions than the Netherlands, and is endangering local elephant and tiger populations.

The fastest rate of deforestation in Indonesia is occurring in central Sumatra's Riau province, where some 4.2m hectares (65%) of its tropical forests and peat swamps have been cleared for industrial plantations in the past 25 years, the study shows.

Since 1982, about 30% of the province's natural forest has been cleared for palm oil plantations, 24% for industrial pulpwood plantations, and 17% has become so-called wasteland – land that has been deforested but not replaced by any crop cover. Twenty-five years ago, according to the report, forest covered 78% of the Riau province. Today it covers just 27%. In just one year, 2005-06, it lost 286,146 hectares – 11% of forest cover

Illegal and legal forest clearance for the development of settlements, infrastructure and agriculture has traditionally driven deforestation in Riau, but the "speed and finality" of forest conversion for the rapidly expanding pulp and paper and palm oil industries is matched "by no other type of deforestation", the report says.

This map shows the location of the Sumatra Earthquake of 2004 and the aftershocks.
What is most likely inferred about the aftershocks, based on this map?

A. They were mainly large and some could be considered earthquakes on their own.
B. They were felt for many weeks after the original earthquake.
C. They were concentrated in one area of the Indian Ocean.
D. They were mainly small and unable to be felt by most people.

Answers

Answer:

Earthquakes occur in the crust or upper mantle, which ranges from the earth's surface to about 800 kilometers deep (about 500 miles).

The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.

Also, the depths of earthquakes gives us important information about the Earth's structure and the tectonic setting where the earthquakes are occurring. The most prominent example of this is in subduction zones, where plates are colliding and one plate is being subducted beneath another. By carefully plotting the location and depth of earthquakes associated with a subduction zone, we can see details of the zone's structure, such as how steeply it is dipping, and if the down-going plate is planar or is bending. These details are important because they give us insight into the mechanics and characteristics of the deformation in the subduction zone.

Within continents, and along continental plate boundary transform faults such as the San Andreas, faults are only active in the shallow crust - perhaps to depths of approximately 20 km.

Accurately determining the depth of an earthquake is typically more challenging than determining its location, unless there happens to be a seismic station close and above the epicenter. So generally, errors on depth determinations are somewhat greater than on location determinations.

A long-term shifts in temperatures and weather patterns either by natural like changes in solar cycle or artificial level leads to climate change.

Artificial or man-made cause refers to burning fossil fuels which generates greenhouse gas and it act as a blanket covered over  the Earth by raising temperatures.

The two major greenhouse gases cause climate change includes carbon dioxide and methane.

These  gases comes from  gasoline use during car driving or coal for heating.

Deforestation also responsible for the release carbon dioxide where as Landfills for garbage are act as a  source of methane emissions.

what could be the possible shape of universe with an evidence. ​

Answers

Answer:

Explanation:

8

When we talk about the "shape" of the universe. It is its intrinsic shape, not the embedding of the universe within a larger space.

It does make sense to talk about the intrinsic shape. Properties like "curvature" can be measured from inside a shape, you don't need suppose that the universe is "in" something to talk about its shape.

Now the space of the universe is three dimensional, this creates visualisation problems. So I'm going to first talk about an imaginary 2d universe:

A 2d universe could be flat, with a curved boundary (like a disc) Or it could be flat with no boundary (an flat infinte plane). Or a 2d universe could be intrinsically curved. If it has positive curvature it could be like the surface of a ball (positive curvature, finite with no boundary) Or shaped like a bowl (positive curvature) Alternatively it could have negative curvature: it could be shaped like a "Pringles crisp" These have negative curvature (this can happen with or without a boundary). Finally there could be regions with different curvature: positive in some parts, negative in others.

The same possibilities exist for our universe: It could be flat (with or without boundary) It could be positively curved (This is intrinsic curvature and your brain can't visualise this for a 3d shape) Or it could be negatively curved (again, don't try to visualise this for a 3d shape, you can't). In the case of positive curvature, it could be finite and unbounded, but for negative curvature, it must either have an edge, or be infinite.

So mathematically these are the possibilities. What does the science say?

We can measure the curvature on large scales. Our measurements are not perfect, there is some room for error. We measure the large scale mass/energy density of the universe, since curvature is caused by gravity, and gravity is caused by mass and energy. If the mass/energy density is > 1 then space would be positively curved. We actually find that the energy density is 1.00±0.02 That is the universe is either flat, or very nearly flat.

No there are profound problems with supposing that the universe has a boundary. But there are also problems with supposing it to be infinite. Scientifically, no edge has ever been detected. So when we build models of the universe, we will generally suppose to have no edge.

Thus our "best guess" is that the universe is uncurved and infinite.

how did the industrial revolution affect migration​

Answers

Answer:

How did the Industrial Revolution affect migration?

The Industrial Revolution had a prodigious impact on migration from 1750-1900. -Industrialization: New innovations were seen throughout this time period, and factories began sprouting across all of Europe. Factories centralized the production of food and common goods resulting in increased migration to cities.

What is the relationship between industrialization immigration and urbanization?

One important result of industrialization and immigration was the growth of cities, a process known as urbanization. Commonly, factories were located near urban areas. These businesses attracted immigrants and people moving from rural areas who were looking for employment. Cities grew at a rapid rate as a result.

Did ethnic enclaves have a positive or negative impact on immigrants in the late 1800s provide evidence to support your response?

The late 1800s saw an enormous influx of immigrants who came to the United States hoping to find better opportunities. Ethnic enclaves had a positive impact on immigrants as it allowed them to have a sense of community in their new country. It also helped them keep their culture and identity alive.

Why does Canada attract immigrants?

With a strong economy providing numerous opportunities and a culturally diverse population, many foreign-born citizens have reaped the rewards of immigrating to Canada. Its educational system makes it attractive to immigrants, and has laid the foundation for future innovation and progress for all of Canada.

Answer:

The Earth, Sun, and Moon

The Earth

Earth, which is our base from which we look into space, is constantly moving. Understanding this movement is one of the most useful and important things in astronomy.

The earth orbits the sun in an elliptical orbit and the moon orbits the earth with the same kind of orbit. Looking down from the north pole, the earth spins in a counterclockwise direction on an imaginary line called its axis once every day. This accounts for the fact that the sun rises in the east and sets in the west. The earth’s axis is tilted with respect to the plane of its orbit at an angle of about 23.4 degrees. If we position ourselves high above the north pole, we would see that the earth orbits the sun in a counterclockwise motion, coming to the same position among the stars every 365.26 earth days. We would also see that the moon also orbits the earth in a counterclockwise motion. This is illustrated in the following example.

Figure 1: The directions of the orbits of the earth and moon.

The average distance from the earth to the sun, the semimajor axis of its orbit, is 149,597,890 km. This distance was not known until recently and it is called the astronomical unit or AU. The distances of the other planets to the sun are usually measured in astronomical units.

Because of the tilt of the earth, not every place on earth gets light every day. Also, some places have extremely short days.

As the earth revolves around the sun, the place where light shines the brightest changes. This motion gives us the different seasons. For instance, the poles receive less light than does the equator because of the angle that the land around the poles receive the sun’s light. When the north pole is tilted toward the sun, the northern hemisphere is presented to the sun at a greater angle than the southern hemisphere and the northern hemisphere gets warmer. When this happens, the northern hemisphere gets summer while the southern hemisphere gets winter. When the south pole is tilted toward the sun, the two seasons reverse hemispheres. This is illustrated in the following image.

soil erosion in Iran

The removal of fertile topsoil by the action of wind, rain and river water is called soil erosion.

Soil erosion is the process of detachment of soil particles from the parent body or disturbance of the soil structure is known as soil erosion. Generally, soil erosion is called as the creeping death of the soil. Soil erosion is considered as negative soil pollution.

Causes of Soil Erosion:

Soil loss is maximum in the region with high population densities. Globally the present rate of soil erosion is over 2500 million tonnes/year. The chief causes of soil erosion are:

1. Land-use changes involving the destruction of forests and grasslands for expansion of agriculture and other commercial activities. 

2. Overgrazing of pastures. 

3. Fallowing of land for a longer duration. 

4. Overuse of chemical fertilizers under intensive cultivation practices destroys the soil structure consequently the soil becomes susceptible to erosive forces. 

5. Shifting cultivation by tribal population. 

6. Continuous cultivation of the same crop.

Name at least two extinct species that share a close evolutionary relationship with humpback whales.

Answers

Thewissen and other collaborators announced that Indohyus, a small deer-like mammal belonging to a group of extinct artiodactyls called raoellids, was the closest known relative to whales.

Answer:

The extinct species called Pakicétus and Indohyus may have had close evolutionary ties to humpback whales. The differences between Indohyus, Pakicetus, and Humpback whales are that Indohyus and Pakicetus both had legs and lived on land, while whales live in the ocean and have no legs. Although the embryo of a humpback whale has limbs that are dormant when it is adult, this could indicate that the animal's ancestors lived on land. Pakicetus and Indohyus are similar to humpback whales because their heads are shaped like long whale skulls. Everything is constantly changing due to evolution, the fossil record of the humpback whale is probably incomplete.

What conditions will increase a nation's Human Development Index? Check all that apply. 0 A. Long work hours O B. A commitment to the education of its population C. The highest gross domestic product in the world D. People who live longer than the world average ​

Answers

Hey there! I'm happy to help!

The Human Development Index takes into account 3 main things about a country:

1. Life Expectancy

2. Education

3. Standard of Living

Long work hours don't necessarily have to do with any of these categories  and it can also be associated with human rights violations (slavery, sweatshops, etc.), so this will not increase a country's HDI, so A is incorrect.

A commitment to education will definitely increase a nation's HDI. Gaining knowledge is part of human development, and a great education system hugely facilitates that. B is correct.

It might seem like having the highest GDP will make a country have a better standard of living, but this isn't always the case. A country could produce tons of things but pay the workers very little, so this would not lead to a good standard living. Although a high GDP usually means that a country is doing better, it doesn't necessarily increase a nation's HDI, so C is incorrect.

D is correct because living longer means that the life expectancy is higher. This means that better healthcare, services, treatments, medicines, opportunities, etc. are available in the country, and being able to live longer is very important for human development.
