Question

The first step in turning a rock into a sediment is ________. Select one:

a. Compaction
b. Rock is broken into small pieces during the transportation phase
c. Weathering alters the rock
d. Gravity and erosional agents (wind, water, etc.) remove material from the parent rock

Answer 1

The first step in turning a rock into a sediment is weathering alters the rock.

Step-by-step explanation:

The first step in turning a rock into a sediment is weathering alters the rock. Weathering is the process by which rocks are broken down into smaller pieces due to exposure to the elements such as wind, water, and temperature changes. This physical or chemical breakdown of rocks creates the loose particles that eventually become sediment.

Answer 2

The first step in turning a rock into a sediment is Compaction .

Step-by-step explanation:

Lithification is a process of changing rock into sediments. There are two steps for a rock to lithify. These steps are as follows

• The first step of lithification is compaction where sediments are erosed together by weight of the it. Thus, the upper layers of sediments causes compaction of lower layers.
• The next process of lithification is cementation. In this fluids fill the space between the loose particles.

Hence, the first step for turning rock into sediments is compaction.
