exogenic processes

When the upper surface of consolidated rock undergoes constant weathering, it creates broken-up rock called

• bedrock.

• regolith.

• parent material.

• outcrop.

When rock is broken down and disintegrated without any chemical alterations, the process in operation is

• physical weathering.

• chemical weathering.

• hydrolysis.

• erosion.

The fact that water expands as much as 9% of its volume as it freezes is the basis of

• oxidization.

• exfoliation.

• salt crystal growth.

• frost wedging.

________ occurs as rock surfaces heated by the Sun during the day expand slightly, and then contract with nighttime cooling.

• Exfoliation

• Thermal expansion

• Frost wedging

• Salt-crystal growth

When rock is broken down and disintegrated in the presence of water and with chemical alterations to the rock, the process in operation is

• physical weathering.

• chemical weathering.

• mass movement.

• biological weathering.

Chemical weathering is greatest under conditions of

• higher rainfall and temperatures.

• lower rainfall and temperatures.

• higher rainfall, but lower temperatures.

• near absence of rainfall, but higher temperatures.

When rainwater attacks formations of limestone, the minerals dissolve and wash away with the mildly acid rainwater. This is an example of

• oxidation.

• crystallization.

• frost action.

• carbonation.

• windstorm

In which mass movement do rock fragments fall freely through the air?

• rockslide

• rockfall

• slump

• earthflow

What is the downslope movement of soil and weathered rock resulting from the force of gravity?

• Mass Movement

• Landslide

• Mudflow

• Slump
