How does sunlight affect rocks?

Back

Sunlight can cause rocks to expand and contract, leading to cracks and weathering.

Front

What natural force is responsible for forming the Grand Canyon?

Back

Water, through erosion, has carved out the Grand Canyon over millions of years.

Front

What are some examples of erosion?

Back

Front

Can ice cause erosion?

Back

Yes, ice can cause erosion by moving rocks and soil as glaciers melt and flow.

Front

What is a common effect of erosion on landscapes?

Back

Erosion can create valleys, canyons, and changes in the shape of hills and mountains.
