Science Review

The weathering of rocks into small pieces forms what natural resource?

• Minerals

• Water

• Coal

• Soil

How do plants contribute to the formation of soil? Plants -

• cover the soil and shade it from sunlight.

• die, decompose and become part of the soil.

• use soil to grow and develop over time.

• support the animal life in the soil.

A student exploring the formation of soil put rocks in a plastic jar of water and shook it. Afterwards, there were small pieces of broken rock in the water. What process in the formation of soil does this model?

• Weathering of earth materials

• Decay of plant matter

• Formation of various minerals

• Mixing of water and air

Lava from a volcanic eruption can change the Earth’s surface by -

• forming new land

• making oceans boil

• carving deep valleys

• pushing aside hills

Which of the following best describes how earthquakes change the Earth’s surface? Earthquakes -

• throw rocks and ash into the air

• force lava through holes in the ground

• violently shift the surface of the earth

• cause clouds to form and rain to fall

Rocks, loose soil and sand rapidly sliding down a slope are a change to the surface of the earth known as a -

• Delta

• Volcano

• Landslide

• Glacier

Metals can be used to make objects of different shapes and sizes because metals can -

• freeze

• grow

• break

• bend

All of the following are ways we can conserve natural resources EXCEPT –

• using less water

• building new houses

• planting more trees

• reusing paper bags

Coal, oil, and natural gas are useful resources because they -

• produce smoke

• are hard to find

• release energy

• pollute the Earth

Which of the following is a way students could conserve paper?

• Buy only new paperback books.

• Use both sides of the paper in a notebook.

• Pick up paper wrappers in the schoolyard.

• Use paper towels to clean spills in the lab.
