1
What are the three types of seismic waves?
J waves, K waves, and body waves
microwaves, sounds waves, and square waves
longitudinal waves, latitudinal waves, and transverse waves
P waves, S waves, and Surface waves
2
Surface waves are a combination of P and S waves.
False
True
3
What is an alluvial fan?
Cone/fan shaped deposit of sediments formed by a glacier
Cone/fan shaped deposit of sediments formed by stream exit mountain range
Cone/fan shaped deposit of sediments formed by wind
4
What is not true about S waves?
Result from side to side or up and down movement
Result from movement perpendicular to the direction the wave is moving
Result from movement parallel to the direction the wave is moving
5
What are the three primary agents of erosion?
water, wind, and floods
streams, landslides, and rockfalls
water, wind, and glacial ice
weathering, deposition, and transportation
6
Which is not a true statement desribing P waves?
Caused by horizontal ground movement
Caused by ground material moving side to side or up and down
Ground material compresses/expands in the direction parallel to wave moving
Ground material compresses/expands in the direction wave is moving
7
In an alluvial fan the finest and lightest sediments are depostied first since the stream can carry them more easily.
True
False
8
How does sediment grain size change in a large alluvial fan from the top to its outer limit?
Coarsest sediments at the top of the fan, finer deposited farther out
Finest sediments at the top of the fan, coarser deposited farther out
9
Surface waves only involve perpendicular movement.
True
False
10
Gravel and course sand require higher water velocities to be transported than clay, silt, and fine sand.
False
True
