In earth
they are formed by magma and lava
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
There are three main types, or classes, of rock which are:***the differences among these rocks have to do with how they are formed as shown below****.sedimentary, these rocks are joining of pre existing rocks. is kind of like lumps of many small rocks.metamorphic: rocks that have changed due to then being moved or changed in any kind of way. these are the typeshe most rocks areigneous: these are formed by material that comes from the cooling and remains of magma. this is the least common form of rock.
A type of Rock derived from pre-existing rocks that have been changed by HEAT AND PRESSURE.
All three types of rock can be formed from pre-existing rock.
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.

Metamorphic rock
There are 3 main ways for them to be formed. Sedimentary rocks are formed from dirt and sand, and can be found in rivers. Igneous rocks are made from molten magma or lava. Metamorphic rocks are made from already existing rocks, and are changed by pressure or temperature.

Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
Igneous rocks - rocks formed from molten rock of the mantle Sedimentary rocks - rocks found in streams Metamorphic rocks - rocks changed by the effects of heat and pressure
Rocks made from sediments being compacted & cemented together.
Clay is formed from rocks by those rocks being weathered to minute particles, those particles being washed in a river and then deposited. As clay is formed of these "sediments" it is sedimentary.
