The rock cycle is a continuous process through which rocks transform from one type to another. Igneous rocks form from the melting and solidification of any rock at high temperatures, either deep underground or at the surface. Sedimentary rocks develop from the accumulation of sediments eroded from existing rocks, forming at Earth's surface. Metamorphic rocks arise when rocks experience intense heat and pressure without melting, resulting in a change in their crystal structure. This worksheet explores these processes in detail.

Presentation Transcript

The rock cycle
Formation of igneous rocks Formed from any rock so hot it melted.
Igneous rocks
Igneous rocks Formed either at depth or at the surface.
Formation of sedimentary rocks Formed from accumulation of sediments eroded from other rocks.
Sedimentary rocks Formed from accumulated sediments.
Sedimentary rocks Formed at the surface of the earth.
Sedimentary rocks Formed at Earths surface.
Metamorphic rocks Formed when any rock is under intense heat and/or pressure deep beneath the earth's surface.
Metamorphic rocks Metamorphic rocks never melt, the crystals just change form.
