Which type of soil can retain the greatest amount of water- high porosity, low porosity, low permeability or high permeability

1 answer:

3 0

The answer is: HIGH POROSITY.
________________________________
(although low permeability can be associated with greater water retention. Permeability can be affected by particular size. For instance, larger particular have larger poles, so fluid (water) can pass through water quickly (higher permeability and less water retention). As such, smaller particles have smaller pores, so fluid (water) can pass through water LESS quickly (lower permeability and RETAINING MORE WATER.).
_______________________
However, "high porosity" is the best choice.

5 importance of a lowland

1) Lowlands area especially level ones are good for human habitation, hence population and settlements Sheldon concentrated here.

2) Coastal lowlands are sources of mineral deposits such as crude oil.

3) Lowlands favour agriculture

4) lowlands favour construction of communication network such as roads, railways, airports, etc.

What sequence of events can lead to magma becoming soil? a. erosion and deposition followed by exposure to heat and pressure b.

Pavel [41]

The sequence of events that can lead to magma becoming soil is C. crystallization followed by exposure and weathering. Under these circumstances it may happen that magma actually turns to soil - it cools off so much that it becomes the ground we walk upon.

Explain how storms are formed due to rising temperatures and other changes in

astra-53 [7]

Answer:

Hurricanes need a lot of heat to form, which is why they usually occur over tropical seas (at least 26°C).

The sun is close to the equator, providing energy to heat the ocean.

The warm ocean heats the air above it causing it to rise rapidly.

Water evaporates quickly from the hot surface of the ocean, so the rising air contains great amounts of water vapour.

The rising air starts to spin (anti-clockwise in the northern hemisphere)

The centre of the storm - the eye - is calm.

As the air rises it cools, condenses and forms towering cumulonimbus clouds.

The rapidly rising air creates an area of intense low pressure. The low pressure sucks in air, causing very strong winds.

Once the storm moves over land it starts to lose energy and fades.

This article includes a list of general references, but it remains largely unverified because it lacks sufficient corresponding inline citations. (August 2008)

The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and service industries which exist to facilitate the transport, distribution and sale of goods produced in the secondary sector (tertiary).[1] The model was developed by Allan Fisher,[2][3][4] Colin Clark,[5] and Jean Fourastié[6] in the first half of the 20th century, and is a representation of an industrial economy. It has been criticised as inappropriate as a representation of the economy in the 21st century.[7]

According to the three-sector model, the main focus of an economy's activity shifts from the primary, through the secondary and finally to the tertiary sector. Countries with a low per capita income are in an early state of development; the main part of their national income is achieved through production in the primary sector. Countries in a more advanced state of development, with a medium national income, generate their income mostly in the secondary sector. In highly developed countries with a high income, the tertiary sector dominates the total output of the economy.

The rise of the post-industrial economy in which an increasing proportion of economic activity is not directly related to physical goods has led some economists to expand the model by adding a fourth quaternary or fifth quinary sectors, while others have ceased to use the model.
