fossils
They are formed by a plant or animal dying and them the sediment building up around it are the body of the dead creature gets in the rock
small particles of rock are formed by weathering and are transported into the sea where they are deposited (sink) and form a sediment. dead cretures can get inside and that is how fossils are formed
-
Metamorphic rocks are formed by extreme pressure deep within the earth this alters the structures of the existing rock
The physical properties of a metamorphic rock rock are it is small it is hard and the fossils get burnt
Igneous rock forms when molten magma cools, solidifies and crystalizes
-
The size of crystals on an igneous rocks depends on how quickly the magma cools if it cools slowly the rock will have large crystals
Intrusive igneous rocks are the ones that form the crystals underground and have larger crystals extrusive igneous rock form on the surface and have smaller crystals
