Sedimentary rock forms from sand and other particles that are buried, compacted, and cemented together by natural processes. In many locations around the world, sedimentary rock is gradually pushed and pulled into the Earth's interior by tectonic forces. This begins a series of transformations for the rock.
The list below shows one potential series of transformations for sedimentary rock. Choose the answers that correctly fill in the missing steps.

1.Sedimentary rock is pulled into Earth's interior by tectonic forces.

2.Possible answers: The rock becomes cooler as it descends-this changes it into metamorphic rock, or Heat and pressure changes the sedimentary rock into metamorphic.

3.Later, heat rising from below causes part of the metamorphic rock to melt, forming magma.

4.Possible: The magma rises upward and eventually cools to form igneous rock. or The magma sinks downward and eventually heats up enough to form rock.

5.The igneous rock is uplifted to Earth's surface, where it erodes to form new sediment.
