Who proposed the theory of continental drift?

Alfred Wegener 

100

This is the name of the boundary is when two plates move apart

DIVERGENT

100

_______________ faults form when the hanging wall drops down. (<-----    ----->)

NORMAL

100

What is the point on the Earth's surface that is directly above the point where an earthquake originates?

Epicenter

100

What is WED?

Weathering - break down 

Erosion - movement

Deposition - drop-off 


ALL OF SEDS!

200

What is the driving force behind plate tectonics?

Convection Currents

200
This is the name of the plate boundary where two plates move together

CONVERGENT

200

___________ faults form when the hanging wall moves up (--->   <---)

REVERSE

200

What type of seismic wave travels the fastest and can travel through solids and liquids? 

P-wave (compressional wave)

200
What makes up the atomic mass of an atom?

NUCLEUS - P + N

300
What are the 4 lines of Wegener's evidence for continental drift (list)?

1. Continental Puzzle

2. Matching Fossils

3. Ancient Climates

4. Seafloor Spreading

300

This is the name of the plate boundary when two plates slide past each other

TRANSFORM

300

______________ faults have walls that move sideways, not up and down (//)

TRANSFORM or STRIKE-SLIP

300

What type of seismic wave travels the slowest but causes the most damage?

L-wave (surface waves)

300

This is the PHYSICAL solid layer of Earth WHERE CONVECTION CURRENTS occur?

ASTHENOSPHERE

400

What are the three lines of evidence for Plate Movement?

1. Paleomagnetism

2. Ocean Drilling

3. Hot Spots

400

What is the Ring of Fire and why does it exist?

- Convergent Plate Boundary 

- Oceanic-Oceanic Convergence causes the denser plate to SUBDUCT, then molten material rises back to the surface where it erupts and forms and island arc

400

This force is associated with divergence or normal faults

TENSION

400

What is the name of the scale that measures the energy released from an earthquake? 

Moment Magnitude Scale


400

This is the PHYSICAL layer of Earth in which plate tectonics occur and is solid and brittle ranging from 0km to 100km deep

LITHOSPHERE

500

What is the difference between the Physical & Chemical layers of the Earth?

Physical: HOW they respond to stress

Chemical: WHAT they are made of

500

What are continental crust and oceanic crust made of? Which is denser?

O - Basalt - DENSER

C- granite -LESS DENSE


500

This force is associated with transform or strike-slip faults

SHEARING

500

How are stress and strain related?

A force (i.e., compression, tension, shearing) put on a material causes stress; the amount that material deforms or changes shape is the strain on that object.

500

This is the CHEMICAL layer of Earth that is dark in color and extremely dense that is directly below the oceanic and continental crust
