what is the answer in this??
Answers
Answer:
1. A vertical section through different layers of the soil is called the soil profile.
2. A-horizon of soil profile contains humus.
3. The removal of land surface by water, wind or ice is known as soil erosion.
4. A-horizon or topsoil provides shelter for many living organisms.
5. Due to sunlight, the water from the soil begins to evaporate and turns into water vapour. This water vapour when reflects the sunlight appears as if it is shining and hence the air above the soil makes the land look shimmery.
6. 200/20 = 10 ml / min
7. Humus, the organic material in soil, is composed of microorganisms (dead and alive) and decaying plants. The inorganic material of soil is composed of rock, which is broken down into small particles of sand (0.1 to 2 mm), silt (0.002 to 0.1 mm), and clay (less than 0.002 mm).
8. Clayey Soil =
1. Particles are finer
2. Particles are tightly packed
3. Hold a good amount of water
4. It is heavy in weight
5. Rich in humus and organic nutrients
6. Very little air is trapped between the Particles
Sandy soil =
1. Particles are larger
2. Particles are loosely packed
3. Water holding capacity is low
4. It is light in weight
5. Not rich in humus and organic nutrients
6. More air is trapped between the Particles
9. Weathering describes the means by which soil, rocks and minerals are changed by physical and chemical processes into other soil components. The means by which soil, rocks and minerals are changed by physical and chemical processes into other soil components. Weathering is an integral part of soil development.
10.
Soil texture (such as loam, sandy loam or clay) refers to the proportion of sand, silt and clay sized particles that make up the mineral fraction of the soil. For example, light soil refers to a soil high in sand relative to clay, while heavy soils are made up largely of clay.
