Volcano
What is a volcano?
A mountain through which lava, Rock, hot vapor, and gas erupt form Earth's crust.
Define Chemical Weathering
Chemical reactions break rocks into smaller pieces.
Define Medosphere
Bottommost solid rocky layer reaching down to the core.
What are earthquakes?
Shifting movement in the Lithospher's tectonic plates that releases energy.
How is an Igneous Rock formed?
Formed from magma and lava
What is a composite Volcano
Emits a stiff rapidly solidifying lava which forms high steep-sided cones.

Who proposed the continental drift theory and what is it?
Alfred Wegener, Earth's continents were once joined together in a single super-continent, which then broke into pieces and moved apart.
