Rock Types

The different types of rocks

Igneous- When magma/lava cools down and solidifies

Sedimentary-When weathered sediments are compacted/cemented together

Metamorphic-When pre-existing rock changes its composition due to pressure/heat

  2. It depends on the environment where Lithification takes place, for example in desert environment. In desert regions moisture is needed which can cause sediments to stick to one another, almost like glue.
