sand was deposited in a desert. over time, the climate of the area became wetter. a river began flowing through it. layers of silt were deposited by the river. thousands of years later, the environment became dry again. the river dried up, and layers of sand were deposited on top of the older sediment. which rock sequence is more likely to form from the sediment layers described above?
Answer
Explanation:
Step1: Analyze sediment - deposition order
First, sand was deposited in the desert. Then, when the climate became wetter, silt was deposited by the river. Finally, when it became dry again, sand was deposited on top of the older sediment.
Step2: Match with rock - sequence
The bottom layer should be sand (which can form sandstone), the middle layer should be silt (which can form siltstone), and the top - layer should be sand (which can form sandstone).
Answer:
The rock sequence with sandstone at the bottom, siltstone in the middle, and sandstone at the top.
