What is the difference between intrusive and extrusive rocks?
With intrusive, magma is injected into the surroundings of the rock. With extrusive, the magma collects and cools on Earth’s surface.
How do caves form?

What is the highest and lowest point of a wave?
Crest and trough
Mass Movements
Downhill movements of soil and weathered rock resulting from the force of gravity.
How does Frost Wedging cause potholes?

In early Earth, how did the water get from the interior of the Earth to the external parts?
Magma heated and caused the water to become vapor. As the pressure increased, it spewed into the atmosphere, where it cooled, and became the ocean.
Anemometer: what does it measure?
Measures wind speed.
