Question

What do you mean by a rock cycle ​

Answer 1

Answer:

Explanation:

The rock cycle is a concept used to explain how the three basic rock types are related and how Earth processes, over geologic time, change a rock from one type into another. Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time

Answer 2

Hope it helps you =

The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, 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 change as they encounter new environments. The rock cycle 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 containing life, a biogeochemical cycle.

A diagram of the rock cycle. Legend:

1 = magma;

2 = crystallization (freezing of rock);

3 = igneous rocks;

4 = erosion;

5 = sedimentation;

6 = sediments & sedimentary rocks;

7 = tectonic burial and metamorphism;

8 = metamorphic rocks;

9 = melting.
