Statements on soil T1 Most of the soil particles are rock powder 2The leaves from the trees which fall on the soil surface finally mix with the soil 3Animal excreta on the soil makes the soil quality bad4 Wind and climate has an important role in the formation of the soil layer 5If the color of soil is red in a region then most likely the rocks present in the region will also be red 6Rock soil is present on the surface moon. 7Moon soil is highly likely to be fertile 8Soil formation is a very slow process.​

Answer 1

Answer:

true

Explanation:

because most of the soil particles are rocking power

Answer 2

True and false for the given statements with corrections for wrong ones are given below:

1. True

Soils are partially or mostly the product of the disintegration or weathering of rocks and it's minerals. Soil consists of finely crushed rocks. Thus, the statement is true.

2. True

Leaves falling on the ground becomes a soil ingredient at last. The fallen leaves are decomposed or broken down by the action of wind and bacteria or other insects present in the soil. This contributes to the enrichment of nutrients and fertility of the soil.

3. False

Animal excreta is not bad for the soil. The animal manures contain organic substances which help in increasing the organic quality of soil and makes it more fertile.

4. True

Wind and climate play a vital role in the weathering of rocks and help the formation of the layer of soil. Due to climate, the soil gets proper forming conditions and wind carries biological weathering agents for the soil formation.

5. True

The red soil is formed from the weathering of metamorphic rocks which are red in color hence, the areas around red soil will have red rocks.

6. True

Regolith soil is present on earth, Mars, and the moon. This soil constitutes of dust and crushed rocks.

7. False

Regolith soil present on moon is poor in nutrient contents and very infertile.

8. True

Soil formation is a very slow process because it needs weathering and each layer formation. Enough nutrient is needed for fertile soil and each layer takes time to form.
