Define the following in one line:
a. Weathering
b. Topsoil
c. Soil erosion
d. Deforestation
e. Soil conservation
Answers
Answer :
Weathering:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
Topsoil :
Topsoil is the uppermost layer of the soil profile. It is the most fertile layer and contains more humus as compared to the other layers in the soil profile
Deforestation :
Deforestation can be defined as the large-scale removal of trees from forests (or other lands) for the facilitation of human activities.
Soil conservation:
Soil conservation is the prevention of loss of the top most layer of the soil from erosion.

Answer:
A. 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.
B. Topsoil is the upper, outermost layer of soil, usually the top 5–10 inches (13–25 cm). It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs. Topsoil is composed of mineral particles, organic matter, water, and air.
C. Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. ... The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.
D. Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. ... Most often, multiple processes work simultaneously or sequentially to cause deforestation.
E. when a bad soil becomes fertile then the gasses and process are done. The it is easy to cultivate.. so the soil conversion only happens when we add water and fertilisers. ..
