Compare and contrast the formation of igneous, metamorphic and sedimentary rocks and relate them to one another using the rock cycle.
(Explanation Must Include)
- the way each rock type is formed
- how they can transform from one rock type to another using the rock cycle
Transition to igneous rocks-
When rocks are pushed deep under the Earth’s surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it will cool and solidify into an igneous rock. A rock that cools within the Earth is called intrusive or plutonic and will cool very slowly, producing a coarse-grained texture. As a result of volcanic activity, magma (which is called lava when it reaches Earth’s surface) may cool very rapidly while being on the Earth’s surface exposed to the atmosphere and are called extrusive or volcanic rocks. These rocks are fine-grained
