Rock cycle refers to the web of processes that outlines how the three main types of rocks- igneous, metamorphic, and sedimentary rocks, form and break down based on various applications of processes of heat and pressure over due course of time. For example, sedimentary rock becomes slate when both heat and pressure are added to it. The more heat and pressure added, the process of rock metamorphoses is furthered until it changes to gneiss and the rock melts down completely and reforms as igneous rock....

Sedimentary Rocks are defined as those formed by the consolidation of sediments. The various weathering agencies wear down the pre-existing rocks. The weathered products called sediments are carried to water bodies like lakes and oceans by the rivers, where they accumulate and later by compaction and cementation from sedimentary or secondary rocks. Because the sediments are deposited characteristically in the form of layers, these rocks are also called stratified rocks....
The uppermost layer of the Earth’s crust is made up of a complex mixture of minerals, organic matter, water, air, and living things known as soil. It is an essential natural resource that promotes the growth of plants and is crucial to the environment. A vital component of soil is water and air. Nutrients may be delivered to plant roots through water, whereas soil organisms can breathe oxygen because of air. For crops to grow healthily, soil moisture and air content must be balanced. Indian soils can be divided into seven types. They are alluvial soil, black soil, red soil, laterite soil, or arid soil, and forest and mountainous soil,marsh soil....
Western disturbances play a vital part in the Indian climate since they provide relief from the country’s typically dry and scorching temperatures. Extratropical storms known as “western disturbances” migrate towards the Indian subcontinent from the Mediterranean region. They are so named because they create disruption throughout the western states of the subcontinent, including Punjab, Himachal Pradesh, Jammu & Kashmir, and Uttarakhand....
