Weathering

Question 1

Mechanical Weathering

Answer 1

Physical

Question 2

Frost Wedging (Mechanical Weathering)

Answer 2

Liquid Water Freezes, expands and pushes creating cracks.

Cold at times and warm at times

Question 3

Salt Crystal Growth (Mechanical Weathering)

Answer 3

Sandstones and Shale pick up salt and goes to the rocks where it leaves sand to expands

Question 4

Exfoliation

Answer 4

Round Pulton, uplifts, expands creating cracks

EX: Crystals (Onion/Egg pealed back)

Question 5

Chemical Weathering

Answer 5

Hydrolysis, Oxidation and Dissolution

Question 6

Hydrolysis (Chemical Weathering)

Answer 6

The mineral has water in it, changing the minerals and adding acid dissolving elements and serve rocks weathering

Question 7

Oxidation (Chemical Weathering)

Answer 7

when you have a solid element(iron) and mixes with oxygen, The rock becomes weaker and breaks down (shape over closers)

Question 8

Dissolution (Chemical Weathering)

Answer 8

Does not give up minerals
Carbonic acid dissolves limestone
-Depression/Holes in the surface (Floats on the ocean)

Question 9

Biomechanics (Biological Weathering)

Answer 9

Breaking the rocks apart

-trees breaks and push rock apart

Question 10

Biochemical (Biological Weathering)

Answer 10

The acid gets into the minerals to eat away at the rock

-Organic Matter sticking to a rock

Question 11

Angle of Repose

Answer 11

steepest angle that sediments can form without slumping or sliding
-Bigger or more angular it is the higher repose
