Question

Explain the following types of weathering.
1) Exfoliation 2) Granular disintegration 3) Oxidation

Answer 1

Explanation:

1)There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.

2)Granular Disintegration: When the agents of weathering, reduce rocks made up of different minerals to small pieces and fragments, it is called granular disintegration. Exfoliation: The changes in temperature may create fissures or cracks in rocks. ... During the day, ice in the fissures of the rock melts

3)There are different types of chemical weathering, the most important are: Solution - removal of rock in solution by acidic rainwater. ... Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

Hi buddy

Here is your answer

☑️ Exfoliation involves the removal of the oldest dead skin cells on the skin's outermost surface. Exfoliation is involved in all facials, during microdermabrasion or chemical peels. Exfoliation can be achieved by mechanical or chemical

☑️ Granular disintegration is when grains of a rock become loosened and fall out, to leave a pitted, uneven surface because of changing temperature. Rocks are made up of different types of minerals. 4.7.

☑️Oxidation is the loss of electrons. In terms of oxygen transfer, oxidation may be defined as the chemical process in which a substance gains oxygen or loses electrons and hydrogen. When one of the reactants is oxygen, then oxidation is the gain of oxygen. Reduction is a
