Bju and Earth Science and Erosion

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

• water does not weather rocks

• water can harden rocks

• water can harden rocks

• rain

• strong wind

• glaciers

Kayla saw a boulder that was about as large as a small car. What likely deposited the boulder?

• a glacier

• a winding river

• heavy rain

How does wind weather rocks?

• it moves rocks to new places

• it slams sediment into larger rocks

• it rolls rocks along the ground

Which can form when wind deposits sediment?

• a v-shaped valley

• a u-shaped valley

• a landslide

• a sand dune
