3rd CBA Review and Practice #2

The weathering of rocks into much smaller pieces, forms what natural resource?

• minerals

• water

• coal

• soil

In area that receives little to no rainfall throughout the year, what would the soil contain?

• less water

• a lot of different plants

• a variety of insects and worms

• much smaller pieces of rock

Lava from the eruption of a volcano can change the Earth's surface by possibly doing what?

• forming new land

• making the ocean boil

• carving deep valleys

• pushing or moving hills

When earthquakes occur, which best describes how earthquakes may change the Earth's surface?

• throws rocks and ash high into the air

• forces lava through holes in the ground

• violent shifts in the surface of the earth

• causes clouds which leads to rain

What impact or contributions do plants have to the formation of soil?

• cover the soil and share the sunlight

• die, decompose, and then become part of the soil

• use the soil to grow and develop over time

• support the animal life in the soil

In Science lab, we take a mixture of tiny rocks, small twigs, sand, and some dead leaves. What did we just create an example of?

• changes in rocks over time

• life cycle of plants

• how soil formation occurs

• how landforms are created

In Science lab, we took 2 different types of cookies (representing rocks). We shook them slowly over a period of 10 minutes. What were we modeling?

• weathering of rock / earth material

• decaying of plants

• formation of various minerals

• mixing water and air

The image shows a split and shift in the earth's surface. What force would have most likely caused this change?

• river

• flooding

• volcano

• earthquake

When rocks, loose soil, and sand RAPIDLY move down a slope and change the earth surface, this is most likely caused by what force?

• delta

• volcano

• glacier

• landslide

_____________ is a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
