AP State Board Syllabus 7th Class Science Notes Chapter 15 Soil: Our Life<\/h2>\n

\u2192 The soil supports all plants, animals, and microorganisms.<\/p>\n

\u2192 Almost all the things in our surroundings directly or indirectly depend on soil.<\/p>\n

\u2192 Soil is also an essential component of our lives.<\/p>\n

\u2192 Most of our daily life activities are closely related to soil.<\/p>\n

\u2192 We use soil for various purposes.<\/p>\n

\u2192 Soil is good habitat.<\/p>\n

\u2192 We depend on soil for agriculture, construction purposes, making utensils, toys, etc Making pots by using soil is called pottery.<\/p>\n

\u2192 If the proportion of large-sized particles is more, we call the soil sandy.<\/p>\n

\u2192 If the proportion of fine particles is more the soil is clay.<\/p>\n

\u2192 If large and fine particles are present in equal proportions, the soil is called loam.<\/p>\n

\u2192 Water passing down through the soil particles is called percolation.<\/p>\n

\u2192 Soil is made up of distinct horizontal layers.<\/p>\n

\"AP<\/p>\n

\u2192 Soil is formed slowly as rock erodes into tiny pieces near the earth\u2019s surface.<\/p>\n

\u2192 During heavy winds, we observe that the surface soil particles are carried away by air. It is very important to preserve the fertility of the soil.<\/p>\n

\u2192 Soil is a mixture of rock particles and humus.<\/p>\n

\u2192 Clay, loam, and sand are types of soil.<\/p>\n

\u2192 The amount of water that passes through gives us a percolation rate. It is highest in the sandy soil and least in the clayey soil.<\/p>\n

\u2192 The water holding capacity of a soil depends on soil type.<\/p>\n

\u2192 Clay and loam are suitable for growing in sandy loam or black soil.<\/p>\n

\u2192 The soil profile is a section through different layers of the soil.<\/p>\n

\u2192 Removal of topsoil by wind, water, or any other means is known as soil erosion.<\/p>\n

\u2192 Clay: a type of soil that can be easy to roll into a ball or ring and not cracked<\/p>\n

\u2192 Humus: rich dark organic material in the soil.<\/p>\n

\u2192 Loamy: a medium-textured soil containing a mixture of large and small mineral particles. (rich soil)<\/p>\n

\u2192 Sandy: very fine loose fragment of crushed rock.<\/p>\n

\u2192 Percolation: filt\u00e9r, especially through small holes.<\/p>\n

\u2192 Water retention: water holding capacity.<\/p>\n

\u2192 Soil profile: a form of soil.<\/p>\n

\u2192 Soil fertility: production of vegetation in soil.<\/p>\n

\u2192 Soil erosion: removal of topsoil by wind, water, or any other means.<\/p>\n

\"AP<\/p>\n

\u2192 Crop rotatIon: a plant cultivated on a large scale for its produce.

\n\u2192 Making pots by using soil is called a pottery. This is an ancient creative occupation. During the Harappan civilization, different varieties of designer pots and clay utensils were used. Pottery is a cottage industry in our country. Potters make pots by using clay soil on a pottery wheel.<\/p>\n

\u2192 Soil Formation: Soil is formed slowly as a rock (the parent material) erodes into tiny pieces near the Earth’s surface. Organic matter decays and mixes with inorganic material (rock particles, minerals, and water) to form soil. These days farmers test the soil in the field using soil technologies in order to grow suitable crops in the fields. Engineers also test the soil profile before constructing multi-storeyed buildings, bridges, and dams.<\/p>\n

\u2192 Soil Science:
\nSoil science is the study of soil as a natural resource on the surface of the Earth. This includes Soil formation, Classification, and mapping, physical-chemical- biological and fertility properties of soil.<\/p>\n

Sometimes terms that refer to branches of soil such as pedology and edaphology are used as if Syno with soil science. The study of the formation, chemistry, more and classification of soil is called pedology’. The study of ii of soil on organisms, especially on plants is called edaphology.
\n\"AP
\nThe diversity of names associated with this discipline is related to the various associations concerned. Indeed engineers, agronomists, chemists, geologists, physical geographers, ecologists, biologists, microbiologists, silviculturists, archeologists all contribute to further knowledge of soil and the advancement of soil science.<\/p>\n","protected":false},"excerpt":{"rendered":"
