What is Granite? (i) Red soil is red in colour. Reasons for low productivity: (i) Deficient in nitrogen, humus. Red soil is formed due to the weathering of sedimentary rocks. It is rich in iron and hence appears red in colour. Soil color is associated with the parent material from which it was formed. Red soil is formed by weathering (slow breaking) of old crystalline igneous and metamorphic rocks. I googled your question and this is one answer I received: The process laterization in soil occurs in the region where the atmospheric temperature is very with very high annual rain fall. Processes Affecting Latosol Formation Red soil may be present in warm climates. Soil formed by intense leaching is (a) Alluvial soil (b) Red soil (c) Laterite soil (d) Desert. Answer. Answer: Red Soil is formed due to the prolonged weathering of the old crystalline rocks. Laterite soil is formed under conditions of heavy rainfall with alternate wet and dry periods, and high temperature which leads to leaching of soil, leaving only oxides of aluminium and iron. They have a mixture of clay and sand. (ii) Large tracts in Maharashtra are covered with black soil. Booker backs landmark bill to protect student athletes From Soil Taxonomy (1975): "The red color of soils is generally related to unhydrated iron oxides, although manganese dioxide and partially hydrated iron oxides may also contribute red colors. Black soil is of red colour mainly due to its iron oxide content. These minerals give the soil its distinctive red colour. Types of Soil in India – Red Soil. Terra rossa ( Italian for "red soil") is a well-drained, reddish, clayey to silty clayey soil with neutral pH conditions and is typical of the Mediterranean region. (c) it is derived from volcanic origin. Here, the soil drainage and air space will depend on the resultant soil type and the compaction and cementation process. The Laterite Soil is the type of soil formed from intense leaching in areas of high rainfall , moisture and high temperature. Question 15: Name the soil which is formed due to high temperature and heavy rainfall with alternating wet and dry periods. Red Soil is formed due to the prolonged weathering of the old crystalline rocks. Click here to get an answer to your question ️ How is red soil formed? Soil Texture: Varies from sand to clay and loam. Answer: (i) This soil is red in colour due to the presence of iron oxide. These are one friable soil with a high content of secondary concretions of sesquioxide clays. It looks yellow when it occurs in a hydrated form. Red soil is formed by weathering of old crystalline igneous and metamorphic rocks. This soil shares 15 % of all types of soil in India. Answer: b.
