List the 5 components of a soil.
Wearthered rocks, water, minerals, air and organic matter.
Explain the origin of organic matter found in the soil.
Decomposers living in the soil decompose the bodies of dead organisms whch lead to the formation of organic matter.
Indicate the importnce of organic matter in the soil.
Organic matter helps the soil to be fertile (good for vegetation).
What are the 2 steps taking place in the process of soil formtion?
(1) weathering of parent rocks./ (2) Decomposition & mixing by living things.
List the factors helping to make soil formation easier and faster.
(1) Rock type. / (2) Climate. / (3) Soil Topography. / (4) Plants and animals.
Explain how rock type affects soil formation.
Soft rocks are easier to be weathered than hard and rigid rocks.
Space between weathered rocks can be filled by:
Air and water.
What climate (weather conditions) are suitable for soil formation?
Warm wet places are more favorable than cold and dry areas.
Explain the importance of topography in soil formation.
Soil develop faster in falt areas than steep slopes, since flat areas have less erosion rates.
Explain how plants and animals help and soil formation.
Plants and animals help in decomposition and mixing soil componenets.
Give the importance of soil stabilization on steep slopes.
Soil stabilization helps to stop soil erosion on steep slopes and make it easier for soil formation.
Give the name of organic matter formed by the decomposition of dead organisms and indicate its position in the soil.
Humus is the name of organic matter and it is found in the top layer of teh soil.
