Question

read the text. then answer the question.
sand, mud, and boulders were deposited at the edge of a glacier.
over time, the glacier melted. a lake covered the area and mud was deposited.
over thousands of years, the lake dried up, and the area became a desert. sand was deposited by wind on top of the older 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
shale
conglomerate
sandstone

Explanation:

Sedimentary rocks form in layers with older layers at the bottom. The first deposit (glacier edge) includes boulders, which form conglomerate. Next, lake mud forms shale. Finally, desert wind-blown sand forms sandstone, the youngest layer.

Answer:

younger
sandstone
shale
conglomerate
