chapter 6 science test

Erosion sorts sediment by its SHAPE

• False, SHAPE should be SIZE

• False, SHAPE should be COLOR

• True

A well rounded rock has undergone MORE erosion than a poorly rounded rock of the same material.

• true

• False, MORE should be LESS

EROSION occurs when weathered material is moved from one place to another.

• False, EROSION should be DEPOSITION

• False, EROSION should be WEATHERING

• true

In an old stream, more deposits are found at the INSIDE of the curve where the water moves slower.

• True

• False, INSIDE should be OUTSIDE

Vegetation not only decreases water erosion during heavy rainfalls, it also INCREASES the likelihood of a mass wasting event.

• False, INCREASES should be DECREASES

• true

One major difference between slump and creep is that SLUMP happens over a long period of time.

• False, SLUMP should be CREEP

• true

• False, SLUMP should be LANDSLIDE

How is wind a weathering agent?

• it dissolves minerals in rocks

• it grinds and polishes rock by moving particles against it.

How are ice and plant roots weathering agents?

• they dissolve minerals in rocks

• they grind and polish rock by moving particles against it

• they expand within cracks in rock to break the rock apart

• they are not weathering agents

Sediment eroded by which means is most likely to be well sorted?

• flash flood

• waves

• storm

• volcanic eruption

You drive down an unpaved road on a dry day, and the dust blows up in clouds behind you.  When you get home, you see that your car is entirely covered in dirt.  What processes have occurred?

• The billowing dust in the air is undergoing erosion. The dust settling on your car has undergone deposition.

• The billowing dust in the air is undergoing deposition. The dust settling on your car has undergone erosion.

• The billowing dust is undergoing erosion. There is no deposition.

• The billowing dust in the air is undergoing deposition. There is no erosion.
