Science Boot Camp - Landforms

Which of these landforms is created by water deposition?

• Canyon

• Sand Dune

• Beach

• Sea Cliff

How does a sharp and pointed mountain become a smooth and rounded hill?

• Weathering

• Deposition

• Earthquake

• Glaciers

Which of these is formed by a glacier moving slowly across land?

• Earthquake

• Hill

• U-Shaped Valley

• Delta

How is a canyon formed?

• Wind blows sediments away.

• A river moves sediments away.

• A river drops all the sediments there.

• Ice scrapes all the sides away.

How does a delta form?

• a river slowing down
• it's just a river that empties into an ocean or lake
• the current of the river speeds up at the mouth causing sediment to wash away
• the current of the river slows down causing sediment to deposit

How does a valley form?

• by a river flowing in between mountains
• it just appears
• by mountains separating
• by volcanoes erupting

Students propped up one end of a tray of sand. They also set up a jar of water and a rubber hose so that water flowed over the sand. They observed how the moving water carried the sand downhill and made a small pile of sand at the bottom of the tray. When the students created the small pile of sand at the end of the flow of water, they modeled the formation of which of the following?

• A. Dunes
• B. Canyon
• C. Plain
• D. Delta

Students used a fan to blow piles of sand. This best models which of the following natural processes that create changes to the land?

• A. Weathering of rocks to make soil
• B. Deposition of sediments to form deltas
• C. Formation and movement of dunes
• D. Carving out plains to create canyons

A river flowing across the rocky surface of the Earth could create which of the following?

• A. Dunes
• B. Mountains
• C. Canyon
• D. Hill

Which of the following changes to the Earth's surface is mostly created by moving wind?

• A. Deep cracks forming
• B. Rocks getting rounded
• C. Large dunes moving
• D. Tall mountains rising
