What causes convection current in the Earth?

• The temperatures we feel outside

• The crusts outer layer

• The uneven heating on each layer inside the Earth

A volcano found in the center of a tectonic plate tends to be a result of which phenomenon?

• strong earthquake

• activity at a hot spot

• pressure in thick sediments that produce heat

• unusually excessive erosion that wears away bedrock

What process is represented by this diagram?

• rotation

• conduction

• radiation

• convection

Which of the following observations best support Alfred Wegener's theory of continental drift?

• Similar animal species are found in Asia and North America

• Patterns of the major oceanic currents stay consistent from year to year

• Changes in Earth's magnetic field have been documented in ocean floor rocks

• Identical fossils are found along the coastal region of Africa and South America

What causes the oceanic crust to be pushed under the continental crust? Use the diagram of the subduction zone to answer the question above.

• the weight of the ocean water on the oceanic crust

• the reduction of friction on the oceanic crust

• the depth of the oceanic crust

• the higher density of the oceanic crust

Which of the following is the MOST recent evidence of plate tectonics?

• volcanic activity and sea-floor spreading at the mid-ocean ridges

• similar fossils found on continents that are now separated by oceans

• the observation that the continents of South America and Africa fit together like in a puzzle

• similar rock formations found on different continents that are now separated by oceans

When tectonic plates move, they can form different landforms. Which is LEAST likely to be associated with the tectonic plate movement that forms volcanoes?

• hot spot

• rift valley

• subduction zone

• transform boundary

Which would produce the most severe earthquake damage along the surface of Earth?

• an earthquake with a shallow focus and a magnitude of 2.5

• an earthquake with a deep focus and a magnitude of 4.5

• an earthquake with a shallow focus and a magnitude of 4.5
