NCERT Solutions for Class 7 Science Chapter 9 - Soil: In this chapter, you will study that soil is one of the most important natural resources. It provides anchorage to the plants and supplies water and nutrients. It is the home for many organisms. Soil is essential for agriculture. Agriculture provides food, clothing, and shelter for all. Soil is thus an inseparable part of our life. The earthy fragrance of soil after the first rain is always refreshing. As you know, weathering of rocks produces small particles of various materials. These include sand and clay. The relative amount of sand and clay depends upon the rock from which the particles were formed, that is the parent rock. The mixture of rock particles and humus is called the soil.

Here are the important topics of NCERT Solutions for Class 7 Science Chapter 9 - Soil mentioned below:

9.1 Soil Teeming With Life

9.2 Soil Profile

9.3 Soil Types

9.4 Properties of Soil

    Percolation Rate of Water in Soil

9.5 Moisture in Soil

9.6 Absorption of Water by Soil

9.7 Soil and Crops

You will also study the soil erosion. The removal of land surface by water, wind or ice is known as erosion. Plant roots firmly bind the soil. In the absence of plants, the soil becomes loose. So it can be moved by wind and flowing water. Erosion of soil is more severe in areas of little or no surface vegetation, such as desert or bare lands. So, cutting of trees and deforestation should be prevented and effort should be made to increase the green areas.
