A VOLCANO!

MAGMA RISES UP through cracks or weakenesses in earth's crust

MART CREC

Pressure builds up inside the earth

Pressure released magma explodes to surface causing volanic eruption.

Lava from the eruption cools to form new crust.

Over time after several eruptions rock builds up and a volcano forms.

Magma chamber = collection of magma

Main vent = main places for magma to escape

Secondary vent = smaller places through magma escapes

Crater = created after an eruption, blows top off volcano
