Question

explain rock cycle with the help of diagram and also describe it

Answer 1

A diagram of the rock cycle.1 = magma; 2 =crystallization (freezing of rock); 3 = igneous rocks; 4 = erosion; 5 = sedimentation; 6 = sediments &sedimentary rocks; 7 = tectonic burial andmetamorphism; 8 = metamorphic rocks; 9 = melting.

As the adjacent diagram illustrates, each of the types of rocks is altered or destroyed when it is forced out of its equilibrium conditions. An igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and are forced to change as they encounter new environments. The rock cycle is an illustration that explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets .

Answer 2

Answer:

The process of transformation of rocks from one form to the other in a cyclic manner is known as the rock cycle. It includes the following processes: Hot lava cools down to form igneous rocks. Igneous rocks are then broken down into small particles which are transported and then deposited.This results in the formation of sedimentary rocks.

When igneous and sedimentary rocks are subjected to great heat and pressure, they change into metamorphic rocks.

Metamorphic rocks under heat and pressure breakdown and form hot lava.

This hot magma then again cools down and forms igneous rocks and the cycle is repeated.
