what is extrusive rock​

Answers

Answer:

Here's your answer

Explanation:

Extrusive rock, any rock derived from magma (molten silicate material) that was poured out or ejected at Earth’s surface. By contrast, intrusive rocks are formed from magma that was forced into older rocks at depth within Earth’s crust; the molten material then slowly solidifies below Earth’s surface, where it may later be exposed through erosion. Extrusive rocks are usually distinguished from intrusive rocks on the basis of their texture and mineral composition.

Explanation:

if place A lies at the height of 2500 meters above the sea level and its surface temperature is 20 degree celcious, estimate the temperature place B at the height of 1500masl? justify?

Answers

Answer:

14°C

Explanation:

Place A = 2500 m = 20°C

Place B = 1500 m = ? °C

First of all, we know that the air temperature decreases with 6°C at every 1000 m.

So, now it is easy to find the temperature from place B.

If in place A, at 2500 m is 20°C, then at place B the temperature will be with 6°C lower.

Place B = 20°C - 6°C = 14°C

define fertility management​

Answers

Answer:

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact.
Advancing food security and environmental sustainability in farming systems requires an integrated soil fertility management approach that maximizes crop production while minimizing the mining of soil nutrient reserves and the degradation of the physical and chemical properties of soil that can lead to land degradation, including soil erosion. Such soil fertility management practices include the use of fertilizers, organic inputs, crop rotation with legumes and the use of improved germplasm, combined with the knowledge on how to adapt these practices to local conditions.

The Joint FAO/IAEA Division assists Member States in developing and adopting nuclear-based technologies for improving soil fertility practices, thereby supporting the intensification of crop production and the preservation of natural resources.
Different approaches to efficiently manage soil fertility
An integrated soil fertility management aims at maximizing the efficiency of the agronomic use of nutrients and improving crop productivity. This can be achieved through the use of grain legumes, which enhance soil fertility through biological nitrogen fixation, and the application of chemical fertilizers.

Whether grown as pulses for grain, as green manure, as pastures or as the tree components of agro-forestry systems, a key value of leguminous crops lies in their ability to fix atmospheric nitrogen, which helps reduce the use of commercial nitrogen fertilizer and enhances soil fertility. Nitrogen-fixing legumes are the basis for sustainable farming systems that incorporate integrated nutrient management. Use of nitrogen-15 lends understanding of the dynamics and interactions between various pools in agricultural systems, including nitrogen fixation by legumes and utilization of soil and fertilizer nitrogen by crops, both in sole and mixed cropping systems.

Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose fertilizer applications, to replenish losses through plant uptake and other processes; and by minimizing losses through leaching below the crop rooting zone by improved water and nutrient application.
The contribution of nuclear and isotopic techniques
The isotopes of nitrogen-15 and phosphorous-32 are used to trace the movements of labelled nitrogen and phosphorous fertilizers in soils, crops and water, providing quantitative data on the efficiency of use, movement, residual effects and transformation of these fertilizers. Such information is valuable in the design of improved fertilizer application strategies. The nitrogen-15 isotopic technique is also used to quantify the amount of nitrogen fixed from the atmosphere through biological nitrogen fixation by leguminous crops.

The carbon-13 isotope signature helps quantify crop residue incorporation for soil stabilization and fertility enhancement. This technique can also assess the effects of conservation measures, such as crop residue incorporation on soil moisture and soil quality. This information allows the identification of the origin and relative contribution of different types of crops to soil organic matter.

two pieces of evidence which indicate that Paarl receives seasonal rainfall​

Answers

Explanation:

Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more than others. This paper presents the findings on research to determine whether shifts in seasonal rainfall patterns are indeed already visible in historical rainfall data in the Western Cape of South Africa. The paper aims to provide some baseline information which can stimulate further research in this field. Different analytical methods were formulated to investigate the relationships between daily rainfall indices over a set timescale. Data was collected from the South African Weather Service (SAWS) in order to accumulate 20 rainfall stations, each with at least 100 years of historical daily rainfall data. Statistical analysis, linear trend line distributions, time lag comparisons, cumulative distributions, moving average plots and autocorrelation relationships were applied to the data. The results of the analysis indicated that (1) the rainfall season undergoes fluctuations of wetter and drier years (approximately 20-year cycles), (2) the South Coast region exhibits a shift towards a longer rainfall season, and in contrast the Mediterranean region is shifting to a shorter rainfall season when linear trend lines were analysed, and (3) the moving average plots showed only isolated seasonal shifts at the boundary months.

7. Describe the difference between a command, a market, and a mixed economy. (3 points)

Answers

Hey there! I'm happy to help!

-------------------------------------------------------------------------------

COMMAND ECONOMY

A command economy is an economy that is controlled by the government or the state. The government dictates what will be produced, how much of it will be produced, and the method by which it will be produced.

This is the type of economy found in socialist and communist countries, where the government has much more power to plan the economy to improve it for the citizens of the country. The means of production are collectively owned.

This economy can be found in countries such as China, Vietnam, Cuba, Venezuela, and Laos.

-------------------------------------------------------------------------------

MARKET ECONOMY

A market economy is one that is controlled by the customers and businesses. As a consumer, you vote with your dollars. If nobody buys a product that a company makes, the company will stop making that product. The companies individually decide what they will produce, how they will produce it, and how much of that thing they will produce.

This is the type of economy usually found in countries with a smaller government, where the government has less control of the economy and it is controlled by the people, companies, entrepreneurs, etc.

This economy can be found in countries such as the United Kingdom, Australia, Singapore, Canada, etc.

-------------------------------------------------------------------------------

MIXED ECONOMY

A mixed economy is a hybrid of command and market economies. What happens is that there are government has control over goods and services in the economy via things like higher taxes, welfare distribution, etc.

The government also can control companies to some degree with regulations. It isn't necessarily socialist or communist as the government doesn't have complete control, but it does have more control over the economy, and this tends to fall on a spectrum. Mixed economy can be an umbrella term for different combinations with companies and the government.

Examples of countries with mixed economies include France and the United States.

Have a wonderful day and keep on learning! :D

COMMAND ECONOMY
