EVERYDAY SCIENCE

Detailed explanation-1: -There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes-such as melting, cooling, eroding, compacting, or deforming-that are part of the rock cycle.

Detailed explanation-2: -Crystallization, erosion and sedimentation, and metamorphism transform one rock type into another or change sediments into rock. The rock cycle describes the transformations of one type of rock to another.

Detailed explanation-3: -Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering-chemical weathering.

Detailed explanation-4: -The rock cycle describes how the three main rock types-igneous, sedimentary, and metamorphic-change from one type to another. These changes occur through processes such as melting, solidification, and lithification. The rock cycle is driven by energy from Earth’s interior and the sun.
