100
List the three different spheres of the Earth and label what each sphere is made of
lithosphere-the solid part/ rock part hydrosphere-the water atmosphere-gases/air
100
__________ of the Earth is covered by ocean water
3/4 or 75%

The liquid part of the Earth that s-waves can not travel through
outer core
100
There is a lot of __________________________ at the mid-Atlantic ridge
volcanic activity
100
List the three ways that mountains are made
folding, faulting, volcanoes
200
The process where material at the Earth's surface is removed and carried away
erosion
200
Area of the seafloor that slopes gently away from the coastline of most continents
continental shelf
200
The name of the single land mass that was once believed to exist
Pangea
200
The Earth's crust is broken into large pieces or _________ that interact in several ways
plates
200
The number of waves past a point during a period of time is
frequency
300
The breaking down of rocks into smaller pieces by rain, ice, and atmospheric gases
weathering
300
a mountain chain where rising magma forms new ocean crust
mid-ocean ridge
300
There are two kinds of crust. Name them and list what the main component of each is
oceanic-basalt continental-granite
300
List two kinds of activity that happen at the edges of plates
mountain building volcanic activity earthquakes
300
layers of sedimentary rock that slowly raised above sea level to form a broad, flat region at low elevation
plain
400
The two types of weathering
physical and chemical
400
A steep drop off at the edge of a continental shelf
continental slope
400
The part of the Earth that flows slowly and causes plates to move
mantle
400
What is evidence of seafloor spreading?
matching magnetic polarity matching sediments and fossils trenches at subduction areas
400
List the three different kinds of waves
p-wave s-wave l-wave
500
masses of ice that creep along grinding up and removing rock material from the land surface
glaciers
500
Found where a plate of ocean crust collides with another plate and is forced to slide under
trench
500
Give one piece of evidence for the theory of continental drift
continents fit together like puzzle pieces matching fossils on different continents matching rocks, mountains and glacial features
500
Describe what causes the seafloor to spread and the continents to drift
heat flowing upward from inside the Earth that carries new rock to the surface and slides crust apart
