Verified
A sandstone with a pinkish or reddish color that is the result of oxidation of iron-bearing minerals indicates the sand was:
A) deposited on land and exposed to air
B) deposited offshore in or near a reef
C) deposited offshore via a turbidity current
D) deposited onshore but strongly mixed with organic material
Oxidation
Oxidation is a chemical reaction in which a substance loses electrons, often resulting in rust in metals or changes in rock minerals due to exposure to oxygen and water.
Iron-bearing Minerals
Minerals that contain iron as a significant component, often influencing the rock's color and magnetic properties.
- Deduce the sedimentary environment through the evaluation of rock features and sedimentary formations.

Final Answer :
A
Explanation :
The pinkish or reddish color in sandstone is typically due to the oxidation of iron-bearing minerals, which occurs when the sand is exposed to air. This suggests that the sand was deposited on land, where it could interact with oxygen in the atmosphere, leading to the oxidation process.
