What is crust, mantle, outer and inner core?
The idea of giant plates moving slowly across the Earth’s surface
What is plate tectonics?
The solid upper mantle and crust combine to form this rigid shell
What is the Lithosphere?
Physical remains or traces of plant or animal that lived long ago
What is a fossil?
Label the three types of boundaries or faults 1. 2. 3.
1. Diverging 2. Converging 3. Sliding?
Melted rock below the Earth’s surface
What is magma?
Many earthquakes and volcanoes occur in this zone that borders the Pacific Ocean
What is the Ring of Fire?
Molten rock that is on the surface
What is lava?

What are seismic waves?
Cracks in the Earth crust along which movement takes place
What is a fault?
Violent shaking of the Earth’s crust
What is an Earthquake?
A point underground where faulting (movement) occurs
What is the focus?
The point on the surface directly above the movement underground
What is the epicenter?
Mountains that form wherever faulting occurs
What are fault-block mountains?
Mountain ranges that form because of two plates converging together causing them to fold
What are fold mountains?
What keeps mountains from growing up and up and up
What is weathering and erosion?
These types of mountains are formed due to volcanic material bulging up through the Earth’s crust
