Surface Processes Quiz

Question 1

Weathering

Answer 1

breakdown of rock material (chemical or physical)

Question 2

Chemical weathering

Answer 2

happens more in hot and wet environments

A chemical change results (example: carbonation/cave formation)

Question 3

Physical weathering

Answer 3

the process that breaks rocks apart without changing their chemical composition.

Question 4

rock abrasion

Answer 4

the process of scraping or wearing down by friction (water, other rocks, etc.)

some rocks are more resistant to weathering than others

Question 5

Erosion

Answer 5

transport/movement of rock material

Question 6

How quickly water flows in a stream is based on three factors:

Answer 6

gradient/slope
Volume of water (discharge)
Shape of stream channel/friction

Question 7

Erosion in a stream happens on the

Answer 7

outside of the bend/meander

water is flowing faster

Question 8

Streams can carry/move sediments in 4 ways

Answer 8

flotation, suspension, traction (bedload), solution (dissolved → salt water)

Question 9

suspension transport

Answer 9

small particles held up within the water

Question 10

traction transport

Answer 10

large boulders rolled at high flow

Question 11

solution transport

Answer 11

rocks that have been dissolved into the water by weak acids

Question 12

flotation transport

Answer 12

floating across the stream ig

Question 13

Deposition

Answer 13

when weathered particles drop/settle

Question 14

Deposition happens along the

Answer 14

inside of the meander

Question 15

water/rivers/wind will sort sediments by

Answer 15

size

Question 16

Three characteristics that make particles settle faster:

Answer 16

Size (larger)
Shape (rounder)
Density (more dense)

Question 17

Vertical Sorting/graded bedding

Answer 17

Biggest particles on the bottom
Smallest on the top

Question 18

Horizontal sorting

Answer 18

Biggest particles dropped/deposited first
Smallest particles dropped last (carried the farthest into lake/ocean
