clams, crustaceans, and fish lived in a sea near a coral reef. after these animals died, some of them sank to the bottom of the reef. their bodies became part of the sediment. over time, the sea began to dry up. eventually, the area was no longer underwater. it became part of a beach. sand was deposited where the coral reef had once been. as the sea level continued to fall, the area became part of a river valley. silt was deposited on top of the older layers of sediment. a rock sequence formed from the sediment layers described above. put the following rocks in order to show what this rock sequence probably looked like. younger limestone sandstone siltstone
Answer
Answer:
younger: siltstone, sandstone, limestone : older
Explanation:
Step1: Identify sediment - deposition order
First, silt was deposited last as the area became a river valley.
Step2: Consider beach - stage deposition
Sand was deposited when it became a beach after the sea began to dry up.
Step3: Identify earliest deposition
Limestone is formed from the remains of marine organisms like clams, crustaceans and fish which sank to the bottom of the reef first, so it is the oldest.
