Answers
Answer:
1.Roots.
2.Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
3.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. 6 - 12+ Earth Science, Geology, Geography, Physical Geography.
4.Soil conservation is the prevention of loss of the top most layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
5.The traditional method of preventing flooding has long been to construct embankments adjacent to the river. ... More often than not, embankments are crudely made from spoil excavated from the river and its banks. Such spoil is often unstable and washed away at the first major flood.
6.Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste.
plants get water through rain and minerals from soil.
dead plants amd decayed animals form soil.
by spreading waste products in soil causes pollution.
