10

Multiple Choice

In some places, timber companies remove all the trees from entire hillsides when they are harvesting logs, and farmers till the soil in the fall and leave the ground bare of plants until it is time to plant in spring. What is the most likely effect of doing either of these things?

1

Plants will sprout better

2

Erosion will happen faster

3

Soil will stay cooler

4

Decomposition will speed up

11

Multiple Choice

What is the difference between weathering and erosion?

1

Erosion breaks down the rocks, and weathering carries the broken pieces away.

2

Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

3

Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

4

Weathering breaks down rocks, and erosion carries the broken pieces away.

12

Multiple Choice

Many places, like the Grand Canyon are the result of a combination of processes that continue to shape Earth, like the water cycle and the rock cycle. Which of the following is responsible for the formation of the Grand Canyon?

1

Too much rain soaking into the ground slows the rate of new rock formation

2

Evaporation of water removes moisture from rock layers in the canyon walls.

3

Large amounts of flowing water increase the rate of weathering and erosion.

4

Decreased rainfall makes the rocks hard and brittle, so that they crumble into pebbles

13

Rock Cycle

media

Is it TRUELY a cycle?

Can rocks change to other types of rock?

14

Multiple Choice

Question image

These Rocks are formed from Magma and Lava

1

Metamorphic

2

Igneous

3

Sedimentary

15

Multiple Choice

The processes involved in the rock cycle take place over millions of years. Which of the following describes a phase of the rock cycle that takes the longest to produce results?

1

Rocks are eroded by wind and rain

2

Eroded rocks travel by wind or moving water

3

Rocks form layers of sediment and solidify into new rocks

4

Rocks are pushed to Earth's surface by tectonic forces

16

Multiple Choice

Question image

These Rocks are formed from Heat and Pressure

1

Metamorphic

2

Igneous

3

Sedimentary

17

Multiple Choice

Why is it most likely that fossils will be found in sedimentary rock rather than igneous or metamorphic rock?

1

Molten sedimentary rock burns up living organisms and fossilizes them as it cools

2

Animals can dig into sedimentary rock, and some are trapped inside and fossilize

3

Sedimentary rock breaks apart most easily, so fossils inside are seen more often

4

Animal remains can get trapped and fossilize as the layers of sedimentary rock form

18
