Earth Science Water and Weathering

What type of landform can form when water weathers and erodes layers of rocks?

• sand dunes

• canyons

• fossils

• mid-ocean ridges

Sarah put four small rocks into a jar of water. She shook the jar very hard for several minutes. When she looked at the jar, she saw the four rocks plus little pieces of sand in the water. What can she conclude from her observation?

• water can weather rocks
