Answer 1

Answer:

1 is up in the picture

Weathering

2 ) Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

3 ) it is usually seen that the clayey soil gets easily waterlogged despite of less rainfall. This is because, the capability to soak water by the clayey soil is quite less and due to the small amount of water only, it gets logged.

4 ) Soil water holding capacity is a term that all farms should know to optimize crop production. ... The larger the surface area the easier it is for the soil to hold onto water so it has a higher water holding capacity. Sand in contrast has large particle sizes which results in smaller surface area.

5 ) Soil is one of the earth's most important natural resources: it underpins human food production systems, supports the cultivation of vegetation for feed, fibre and fuel, and has the potential to help combat and mitigate climate change

6 ) Different types of soil conservation methods prevent earth runoff, pollution, sedimentation in water objects, and protect bare surfaces from cracking and erosion due to water, wind, and excessive heat. Soil conservation strategies rely on three basic steps: Obtaining proper knowledge of the land resource use.
