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.

which areas of Earth receive the greatest and the least solar irradiance?

Answers

Answer:

hope this helps

Explanation:

Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles

Answer: this is the answer

Explanation:

The regions closest to the equator receive the most direct sunlight because the light is arriving at an angle close to 0°. As a result, a lesser area is illuminated and so there is greater solar irradiance. The regions nearest to the poles receive sunlight at more of an angle, resulting in a larger area of illumination and therefore less solar irradiance.

Answers

Answer:

Planetary orbits around our Sun are not perfect circles.  They're ellipses--a loose term to use is oval or ovoid.  At some point Earth gets to its closest point along its orbital path to the Sun .  6 months later it will be at its farthest away.  The distance from the Sun is not what causes the seasons.  The amount of direct sunlight hitting a certain hemisphere of Earth is what causes the seasons.  So, when the Earth's axis is tilted so that the Northern Hemisphere is titled toward the Sun, it's summer time in the Northern Hemisphere. When the Northern Hemisphere is tilted away, it's winter.  So, even though we are closer in distance during January through March, we in the Northern hemisphere are tilted away and it is winter for us.  Yes, that means it is summer in the Southern Hemisphere.

Answer From Gauth Math

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.

B. They were felt for many weeks after the original earthquake

Day and night are equal in equator. Why?

Answers

Answer:

The reason we on Earth have equinoxes at all is because the Earth's axis is tilted. ... Earth's axial tilt also means that our planet's equator is tilted relative to the plane of its orbit around the Sun – what astronomers call the “plane of the ecliptic”.

Explanation:

As the sun rays fall straight and two halves of the earth can be made through equator,it represents the equal effect on both parts so,day and night are equal in equator.

When there is competition for land, what are some things stakeholders can do to have their voices heard?

Housing development is a solution to increasing housing demand with the rise in population, but this cannot be achieved without causing various environmental impacts. If you lived in Georgia, would you want this land to be developed or preserved? Why?

Answers

The land should not be developed.

The stakeholders can do shutdown their businesses and stop doing business activities to have their voices heard. This piece of land should not be developed, it can be preserved because this is the only land left where the organisms live.

If this land is also developed, then the extinction of animals occurs and the whole biodiversity is eliminated from that area so in my opinion, the land should be preserved for the animals so it is recommended that the land should not be developed.

what two structures are located at 34°00′12″S 151°06′48″E

Answers

Hey there! I'm happy to help!

When dealing with coordinates, it is very important to remember that 1 degree is about 60 miles. Also, latitude is North and South while longitude is West and East.

Latitude is based around the Equator, while longitude is based around the Prime Meridian. It is very good to know where these are on a map they are what the coordinates are based around.

It is also very beneficial to remember that the tropic of cancer (which is about at the latitude (North and South) of Mexico, Southern China, etc.) is at 23.5° N, while the tropic of Capricorn (South Africa, Central Australia, Northern Chile) is at 23.5° S.

The arctic and Antarctic circles are both at around 66.5° North and South respectively.

The International Date line (which goes through the center of the Pacific Ocean) is at 180° longitude.

So, since our first coordinate has an S, we know that it is going to be South of the Equator. It is further South than the Tropic of Capricorn since 34° is greater than 23.5°. These structures are going to be about 2040 miles South of the equator (60×34). This is also about halfway between 0 and 66.5 degrees, so it is about in the center of the Southern Hemisphere.

We also see that we are 151° E. This is closer to that International Date Line which goes through the center of the Pacific Ocean, which is a very large ocean. It is about 2000 miles away from it.

If you look at a map, you can see that the Tropic of Capricorn goes through Central Australia. We know that it is South of this tropic by about 660 miles, and it makes sense that it could still be in Australia because Australia is an enormous country. Australia is also very far East from the Prime Meridian in London, so this matches our 151° E coordinate.

This is probably in Southern Australia as it is 660 miles South the center. Most of Australia's population is in the Southern part of Australia, so it makes sense that there could be two structures here. The most notable Australian city is Sydney, so since we are being asked to find two structures just given the coordinates, they are most likely famous and Sydney is the most famous city in this area, this is most likely the location for our city.

What are very famous structures in Sydney? Well, the first one that comes to mind is the Sydney Opera House. Right next to it is the Sydney Harbour Bridge, which is the largest steel bridge in the world with arches. Since these are right next to each other and are two famous structures around these coordinates, these are most likely the two structures.
