Question

The image shows a sandstone formation with visible bands of different colors. What do the bands indicate about how this sedimentary rock was formed? Choose two answers

A. The rock was made from more than one type of material
B. Water was absent during the compaction and cementation process
C. Sediments and other matter were deposited in layers before lithification
D. The rock was stretched horizontally by the pressure from surrounding rocks.
E. Layers of hot liquids in the rock cooled and solidified at different temperatures

Answer 1

A. The rock was made from more than one type of material

C. Sediments and other matter were deposited in layers before lithification

Answer 2

Option A, The rock was made from more than one type of material

Option C, Sediments and other matter were deposited in layers before lithification

Step-by-step explanation:

The process of lithification involves reduction of water within the pores of rock when external force and pressure is applied. After this process the process of stratification starts. Stratification leads to formation of layer of different rock type ( different composition and material) under the application of pressure and temperature as shown in this image.

Hence, option A and C is correct.
