crust
crust involves
continental crust
oceanic crust
The thickest layer beneath the crust.
Made of hot, semi-solid rock that slowly moves.
mantle
A layer of liquid metal (mostly iron and nickel).
Responsible for creating Earth’s magnetic field.
outer core
A solid ball of metal (mostly iron).
The hottest part of Earth, but solid due to high pressure
inner core
is a scientific theory that explains how landforms are created from the movement of the Earth. The earth’s crust is broken into Seven large plates and into several smaller plates.
Plate tectonics
Primarily, earthquakes and volcanoes occur in a pattern that runs between continents and oceans.
coast
are often formed inside continents or near their edge.
mountain ranges
occur when plates collide with each other. Volcanos and Earthquakes commonly occur along
Convergent boundaries
occur when plates move away from on another. When they move apart, water or magma fills the space and creates new land.
Divergent boundaries
