Sedimentary Processes

Mechanical weathering is

• a process where rocks break down into smaller sediments and don't change chemically.

• a process where rocks break down and change chemically into sediments.

• a process where sediments are transported to another location.

• a process where sediments are layed down.

Chemical weathering is more common in

• cool and damp climates

• cold and dry climates

• warm and dry climates

• warm and moist climates

Transportation of sediments to new locations is also called

• deposition.

• compaction.

• erosion.

• lithification.

Which of the following are agents of both weathering and erosion can, and has moved the largest materials the greatest distance?

• gravity

• wind

• running water

• glaciers

Deposition most commonly occurs

• when sediments are being transported.

• when sediments in a water body slow to a point where the settle out of water.

• on land where you have the lowest point.

The process that occurs as successive layers of sediment are deposited in a basin is called

• lithification

• cementation

• erosion

• weathering

As layers of sediments get deposited an lithified, the sediment clasts in the lower layers become

• eroded

• weathered

• compacted

• deposited

The process where ground water in compacted sediments dissolves minerals and glues them together is called

• compaction

• cementation

• chemical weathering

Which of the following types of sedimentary cement will fizz in acid?

• Calcium Carbonate

• Silicate

• Iron oxide

A sign that a sediment clast has been transported a long ways from its parent rock would be

• that its large and angular.

• that its small and angular.

• that its small and rounded.

• that its large and rounded.
