ROCKS

TYPES OF ROCKS

• igneous rock- Rock that has been formed from magma or lava

• sedimentary rock - Rock that has been formed by layers of sediment being pressed down hard and sticking together. You can see the layers of sediment in the rock.

• metamorphic rock - Rock that started out as igneous or sedimentary rock but changed due to being exposed to extreme heat or pressure.

Some more terms to remember

• magma - Molten rock that remains underground. 

• lava - Molten rock that comes out of the ground is called lava.

• sediment - Natural solid material that is moved and dropped off in a new place by water or wind, e.g. sand.

• permeable - Allows liquids to pass through it.

• impermeable - Does not allow liquids to pass through it.
