Scientists have discovered that the mountains on the east coast of South America closely match the mountains on the west coast of Africa. How can two landforms that are so far apart be related?
A. continental drift
B. earthquakes
C. erosion
D. volcanic eruptions
A. Continental Drift

Where are most volcanoes found?
Along plate boundaries

What are the 3 types of waves released by an earthquake?
Primary (p) waves
Secondary (s) waves
Surface (lg) waves

A giant wave caused by an earthquake under the ocean is a(n)
A. focus
B. mercalli
C. tsunami
D. epicenter
C. tsunami

What do earthquakes and volcanoes have in common?
Both occur at or near plate boundaries
200
What is the difference between primary waves and secondary waves?
primary waves move faster and can go through solids and liquids
secondary waves move at half the speed of primary waves and can only go through solids
300
Consists of gases around and above Earth
Atmosphere
300
The sudden movement of Earth's crust
Earthquake

Which of the following scales measures the amount of energy released by an earthquake?
A. richter scale
B. mercalli scale
C. magnitude
D. bathroom scale
A. richter scale
300
What are the 3 major layers of Earth?
Crust, Mantle, Core
300
How do we determine where an earthquake is taking place?
We use 3 seismometer stations to pinpoint the location of the quake because only 1 point will overlap in all 3 zones
400
The movement of pieces of weathered rock from one place to another
Erosion
400
A crack in Earth's crust
Fault
400
Which of the following causes chemical weathering?
A. ice
B. wind
C. water
D. acid rain
D. acid rain
400
What is the difference between erosion and deposition?
erosion is moving sediment/rock, deposition is when rock/sediment finally settles down in 1 place
400
How can an earthquake be compared to tossing a rock into a pond?
An earthquake has a start spot called a focus just like a stone has a point where it hits the water. After that, ripples of energy move outward in all directions just like they do in a pond when the stone hits a spot.
500
An unmoving pool of magma below Earth's crust
Hot Spot
500
The measure of the amount of energy released by an earthquake
Magnitude
500
Trenches, rift valleys, and abyssal plans are all
A. features of topographical maps
B. features of the ocean floor
C. examples of water features
D. examples of land features
B. features of the ocean floor

What is weathering? Give a specific example of how it happens.
Weathering is the breaking down of rock into smaller pieces. An example is water freezing between cracks in a rock and breaking it apart.

What is the difference between the richter scale and the mercalli scale?
Richter scale measures energy released by an earthquake.
Mercalli scale measures the effects of an earthquake like perceived damage
