Question

This example of sedimentary rock is formed when rock fragments, minerals, and the remains of plants and animals are deposited as sediments and are then
A) chemically weathered by water.
B) compacted and cemented together.
C) recrystalized under the weight of the layers.
D) melted due to increased temperature and pressure.

Answer 1

Answer: The answer is B

Explanation: This is because they are compacted together. Most often the rocks you see are sedimentary. For example, a comgermarete.

Answer 2

Answer:

Option (B)

Explanation:

The sedimentary rocks are defined as those rocks that are formed due to the compaction and lithification of sediments. These sediments are obtained from the source rock that undergoes the process of weathering and erosion and are deposited in a new type of environment. These sediments then gets accumulated one after another, along with the deposition of other materials such as the minerals and dead remnants of flora and fauna. Over a due course of time, these sediments are cemented and lithified and forms sedimentary rocks.

For example, Sandstone, Siltstone, mudstone, shale and limestone.

Thus, the correct answer is option (B).
