31.What causes the degradation of land? Provide suggestions for preserving land resources

Explanation:

The ever-increasing demand for living space has led to the destruction of forests, resulting in land degradation. Promoting afforestation, regulating the use of chemical pesticides and fertilizers, monitoring overgrazing, and encouraging land reclamation are all ways to slow the rate at which land resources are being destroyed.


32.What exactly is aging?

Explanation:

Enduring alludes to the separating and rot of uncovered rocks. This separating and rot are brought about by temperature variances between excessively high and excessively low, ice activity, plants, creatures, and, surprisingly, human movement. The primary process by which soil is formed is weathering. This process takes millions of years to create soil.



33.What makes water such a valuable resource?

Explanation:

Water is a life-sustaining resource. First and foremost, drinking water is the most fundamental need for life. It cleans our bodies, clothes, and utensils well. For irrigation, farmers rely on water.

Additionally, food is cooked with water. Additionally, electricity comes from water. Water is essential to the growth of plants. In factories, various industrial processes require water


34.Make a brief note about wildlife.

Explanation:

Wildlife is the animal kingdom, which includes animals, birds, aquatic creatures, and insects. These animals supply us with milk, meat, hides, wool, and other essential goods. Bees provide honey and contribute to pollination. They serve as the environment's decomposers. Scavenger birds like the vulture aid in environmental purification. Our ecosystem is made up of wildlife of all kinds.


35.What are the most common kinds of vegetation found worldwide? Describe the vegetation under various precipitation conditions.

Explanation:

The world's most common types of vegetation are forests, grasslands, scrubs, and tundra. In areas of weighty downpour, enormous trees can be found. Where there is a lot of rain, there are a lot of forests. With dampness and precipitation the thickness of backwoods declines. Grasslands can be found in areas with moderate rainfall. We find thorny scrubs and shrubs in diy areas. The leaves of these plants have thorny surfaces and deep roots to prevent moisture loss. The vegetation of the tundra is made up of lichens and mosses. 


36.Give examples of ways to preserve soil.

Explanation:


The following are some common ways to preserve soil:
Mulching. The process of covering the bare ground between plants with a layer of straw-like organic material is known as mulching. It helps keep soil moisture in place. 

Porch Cultivating. Terrace farming is a method of farming in which wide, flat steps or terraces are built on steep slopes to provide flat surfaces on which crops can be grown. These steps or terraces reduce runoff and soil erosion. Intercropping. To keep the soil from being washed away by rain, different crops are grown in different rows and sown at different times in intercropping. Ploughing in a Contour. Contour ploughing is the practice of plowing parallel to the contours of a hill slope to create a natural barrier that prevents water from flowing down the slope. 

Protection belts Shelter belts are rows of trees planted in specific locations to prevent wind movement. Obstacles in the way Stones, grass, and soil are utilized to fabricate obstructions along forms. To collect water, trenches are constructed in front of the barriers.

Dams of rock. Because rocks are piled high to impede water flow, this prevents gullies and further soil loss.


37.What is the threat to wildlife and vegetation? Why is it necessary to preserve them? How might we do this?

Explanation:

Wildlife and forests are a valuable resource. Plants and animals may lose their natural habitat as a result of human activity or climate change. Many species are now extinct, and some are in danger of extinction. Incidents of poaching contribute to their extinction. The ecosystem is made up of many different kinds of plants and animals. Plants give food, oxygen and haven to people and creatures. Milk, meat, honey, and other important products come from animals. If we don't change the natural number of species that live on Earth, the environment is in balance. The ecosystem can be severely impacted by a single extinction. Therefore, it is obvious that plants and animals must be protected. For this purpose, the government has established national parks, wildlife refuges, and biosphere reserves. Poaching must be dealt with severely. Killings without discrimination must be discouraged. Social forestry, or the importance of trees, must be made public. Vanamahotsavas at the regional and community levels should involve students
