Question

The boundaries berween sedimentary rocks that represent separate depositional events are called O regoliths O outcrops O foliations O bedding planes O rock cycles D | Question 9 1 pts The angle of repose for a talus slope commonly lies between 60° and 65 O True O False D | Question 10 1 pts Which of these types of mass wasting is considered to be slow? O avalanche O slump O solifluction D Question 11 1 pts Salt crystal growth causes weathering because O growing salt crystals can wedge apart cracks O chemical reactions with salt weaken some minerals O salt oxidizes readily salt expands when it freezes organisms readily grow on salt crystals

Explanation / Answer

Question 8:  Bedding Planes

They are the easiest and commonly used physical features in stratified sedimentary rocks to subdivide successions.

Question 9:  False

It varies depending on the gravity and the material.

Question 10:  Solifluction

Solifluction which is also called as the creep is the slowest type of mass movement as it occurs when saturated soil slips over hard layers of the subsoil.

Question 11: growing salt crystals can wedge apart cracks

Salt crystals usually expand or grow when they heat up and exerts pressure on cracks it is deposited.
