Question

sand was deposited by waves on a beach. the sand built up in layers. over time, the climate grew colder, and the sea level fell. a glacier formed close to the area that was once a beach. sand, mud, and boulders were deposited at the end of the glacier, on top of the sand. eventually, the glacier melted, and the sea level began to rise. the area was a shallow part of the ocean for a few thousand years and silt was deposited. then, as the area became a deep part of the ocean, a layer of mud was deposited. 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 sandstone conglomerate siltstone shale

Explanation:

Sedimentary rocks form from deposited sediments, with older layers at the bottom and younger layers on top. Beach sand becomes sandstone (oldest). Glacial deposits (sand, mud, boulders) form conglomerate. Shallow ocean silt becomes siltstone. Deep ocean mud becomes shale (youngest).

Answer:

younger
shale
siltstone
conglomerate
sandstone
