Fossils are most commonly found in this type of rock, which is formed from compacted and cemented sediment.

sedimentary rocks 

300

A sudden and violent shaking of the ground caused by the movement of tectonic plates.

when two tectonic plates collide

Convergent boundarie

he longest part of Earth's history spanning from the planet's formation to the beginning of the Paleozoic Era.

Precambrian Time

400

The continuous process by which rocks are created changed from one type to another and destroyed

These geological units are based on major changes in life forms and geological events as evidenced in the rock record

 eras 

periods 

epochs

500

Rocks that have been changed by intense heat and pressure deep within Earth's crust
