Dynamic Earth Pretest

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

Which of these is a direct source of material for the formation of metamorphic rock?

• Clasts
• Magma
• Sediments
• Existing Rock

Where on Earth are tectonic plates located?

• Outer core
• Lithosphere
• Mesosphere
• Asthenosphere

The diagram shows a fault block mountain. At what type of tectonic plate boundary do fault-block mountains most often form?

• Rift
• Divergent
• Transform
• Convergent

Which of these is a type of movement caused by gravity moving wet Earth materials?

• Dune
• Glacier
• Hotspot
• Mudslide

What can cause a chain of volcanic islands to form far from plate boundaries?

• Rifting
• Folding
• Hotspot
• Subduction

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

• Inner core
• Outer core
• Lithosphere
• Asthenosphere

The diagram shows how sediment is deposited as a fast-flowing river reaches a flatter area of land.  Which of these does the diagram show?

• River delta
• Floodplain
• Alluvial fan
• Oxbow lake

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

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
