Geologic Processes

1. Over time, repeated cycles of heating and cooling can cause a rock to crack. The rock may then break into smaller pieces. What is this process called?

• erosion

• deposition

• subsidence

• weathering

2. Which produces the material for the formation of metamorphic rock?

• magma

• sediments

• existing rock

• clasts

Where on Earth are tectonic plates located?

• outer core

• lithoshpere

• mesosphere

• asthenosphere

Which type of movement is caused by gravity moving wet earth?

• dune

• glacier

• hotspot

• mudslide

Which landform was most likely present before a sinkhole formed?

• a cave

• a canyon

• a shallow pond

• a deep river valley

Which layer of Earth does a tectonic plate ride on top of?

• inner core

• outer core

• lithosphere

• asthenoshpere

7. Canyons, caverns, channels, and valleys all form because of erosion by water. Which landform listed is formed mainly because of erosion by groundwater?

• a broad valley

• a narrow canyon

• a human made channel

• an underground cavern

What kind of rock can turn into a metamorphic rock?

• igneous rock only

• sedimentary rock only

• igneous rock, sedimentary rock, and metamorphic rock

• either igneous or sedimentary rock only

9. In places where there is loose sediment and strong wind, the wind can pick up the sediment and carry it. When the wind slows, it deposits the sediment. Which type of sediment will be dropped first as the wind slows?

• the biggest

• the lightest

• the smallest

• the heaviest

10. Landslides, rockfalls, and mudslides are responsible for both erosion and deposition. What force is mainly responsible for the erosion and deposition that happens in landslides, rockfalls, and mudslides?

• ice

• wind

• gravity

• temperature
