What are the Hamptons?
Small crystals form in these types of igneous rocks.
The ocean floor shows this alternating pattern that gives insight to Earth's history.
Magentic Reversals
This type of plate boundary exists at the San Andreas Fault in California.

What is basalt and granite?
Volcanoes, such as those on the western coast of the United States, form at these zones.
What are subduction zones?
An area with a very cold climate is more likely to have this type of weathering.
What is mechanical weathering?

1. Jigsaw Puzzle 2. Rocks 3. Fossils 4. Paleoclimate
Oceanic crust subducts underneath continental crust due to this key difference between the two plates.
What is their density?
This type of mechanical weathering results in rocks "shedding" layers when the pressure drops dramatically.
What is Exfoliation?
This mineral is what tells us the past directions of the Earth's magnetic field.
What is magnetite?
