Water washes away rocks and soil.

200

What soil is sticky and holds too much water to grow plants?

Clay.

200

Are minerals living?

No, minerals are nonliving.

300

What are three different properties rocks can have?

Color / texture / layers / air holes / fossils 

300

How does water weather rock?

Water can wear down or dissolve rock. 

300

How does wind cause erosion?

Wind blows away rocks and soil.

300

What soil does not hold enough water to grow plants?

Sandy soil.

300

Which of the following have bits of living things?

What are rocks made out of?

And what do people make with rocks?

Rocks are made of (one or more) minerals.

How does ice weather rock?

Water goes into cracks in rocks. The water freezes into ice. The ice breaks the rocks apart. 

400

How does ice cause erosion?

Glaciers carry rocks and soils with them as they slowly move. 

400

What soil is soft and crumbly?

Humus soil.

400
Which of the following are living:

backpacks, tent, tree, sandcastle

Tree.

Tell me two things about fossils. 

Fossils are remains of things that lived long ago. Rocks can have fossils. Fossils are found in layers of rock.

Fossils show up as a bumpy texture or pattern on a rock. 

Paleontologists study fossils. 

500

How does wind weather rocks?

Wind blows sand onto rocks, and the sand rubs and wears away rocks.

500

What is the force that pulls objects towards earth, that pulls rocks and soil from wind, water, ice down (so that new land forms when it is dropped in the same place again and again)?

Gravity.

500
What are two building materials people make from soil, and what else do people use soil for?
People make concrete from sand.

People make bricks from clay.

People also use soil to grow food and for pottery.
