Is a floodplain good for growing crops?

Is a floodplain good for growing crops?

Floodplains are the areas of level land located along the stream banks of rivers and streams. These dark-colored soils are rich in nutrients, providing ideal conditions for crop production despite the flooding risks. …

How are floods beneficial to agricultural fields?

Flood water carry nutrients and sediments, which are deposited on food plats. enriching the soil.

How do forest help in causing rain?

Growing trees take water from the soil and release it into the atmosphere. Tree leaves also act as interceptors, catching falling rain, which then evaporates causing rain precipitation elsewhere — a process known as evapo-transpiration.

Why there is no waste in forest?

When the plants and animals die in the forest, this is considered as waste. When they die, the microorganisms present in the soil helps to convert the waste into hummus or nutrients for the soil which in turn used by plants. And, therefore forest doesn’t contain any waste materials.

What would happen if forest disappear?

1 If forests disappear, the amount of carbon dioxide in air will increase, resulting in the increase of earth’s temperature. 2 In the absence of trees and plants, the animals will not get food and shelter. 3 In the absence of trees, the soil will not hold water, which will cause floods.

What can deforestation lead to?

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

Why forests are called green lungs?

-Green lung can be said as a natural area supposed to replenish the air with oxygen by removing the carbon dioxide. -Forests absorb a huge amount of carbon dioxide that circulates in the atmosphere and releases oxygen to the atmosphere. -They are called lungs of the earth.

Which forest is the lungs of the earth?

Tropical rainforests

What is known as green lungs?

Plants release oxygen through the process of photosynthesis which helps the animals for respiration. They also maintain the balance of oxygen and carbon dioxide in the atmosphere. That is why the forests are called green lungs.

What are green lungs called?

Forests are called as the green lungs because they fix the carbon dioxide in the presence of sunlight and convert them into glucose by the process of photosynthesis.

What would happen if forests disappear for Class 7?

If forests disappear, the amount of carbon dioxide in air will increase, resulting in the increase of earth’s temperature. They provide habitat to a large number of animals. In the absence of trees and plants, the animals will not get food and shelter.

How do forests prevent floods?

Forests act as a natural absorber of rainwater and allows it to seep because of roots of trees. When rainwater falls on leaves of trees and plants, it does not fall directly on the ground. It drips slowly on the forest ground (does not stagnate) and hence prevents floods.

How do forests control global warming?

Forests influence climate change largely by affecting the amount of carbon dioxide in the atmosphere. When forests grow, carbon is removed from the atmosphere and absorbed in wood, leaves and soil. This carbon remains stored in the forest ecosystem, but can be released into the atmosphere when forests are burned.

What is the biggest cause of CO2 emissions?

Main sources of carbon dioxide emissions

• 87 percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil.
• The largest human source of carbon dioxide emissions is from the combustion of fossil fuels.
• The 3 types of fossil fuels that are used the most are coal, natural gas and oil.
