How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place.

• makes the rocks last longer.

• expands cracks and breaks rocks.

• causes rocks to fall in landslides.

How do plants weather rocks?

• During photosynthesis

• When roots grow into cracks of rocks and expand the rock breaks.

• When the plant moves water from the roots to the leaves, the rock breaks.

• Plants don't weather rocks.

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging

• chemical weathering

• acid rain

• abrasion

The carrying away of weathered earth materials by water, wind, or ice is called: 

• transportation

• erosion 

• abrasion 

• frost wedging

Deposition changes the Earth’s surface because bits of broken rock and soil _____.

• stop rivers from flowing.

• make rich farmlands.

• are dropped in new places.

• move very slowly.

Some students are testing rock samples they collected. If you wanted to test these rocks for calcite, what would you put in the bottle and what would you expect to happen if calcite is there?

• Put water in the bottle; if there is calcite, the rock will dissolve.

• Put acid in the bottle; if there is calcite, the rock will fizz.

• Put salt water in the bottle; if there is calcite, the rock will turn a darker color.

• Put liquid soap in the bottle; if there is calcite, the liquid will form a dome on the rock.
