REVIEW: Plate Tectonics

Which change is observed due to the convection currents in the mantle?

• Tectonic plates move.

• Water circulates in the ocean.

• Crust becomes hotter, raising the surface temperature.

• Crust becomes more dense, sinking to form trenches.

Earth's crust is divided into different plates. Which two observations support the idea that Earth's plates have been continuously moving?

• The age of the oceanic crust increases with distance from a mid-oceanic ridge.

• Volcanoes along the edge of plate boundaries are made of rocks of similar compositions.

• The oceanic plates are denser than the continental plates.

• Similar types of rocks from undersea coral reefs.

• A fissure between the North American Plate and the Eurasian Plate is about 2 cm wider every year.

A student argues that Africa, Madagascar, and India were once together and later drifted apart due to plate tectonics. Which finding supports the student's argument?

• These regions are located along the equator.

• These regions are connected by the Indian Ocean.

• Rocks of a similar type and age are found in these regions.

• Similar types of climatic conditions are found across these regions.

The map shows the Himalayan Mountains through several countries in South Asia. Which theory explains the formation of the Himalayan Mountains?

• The Indian and Eurasian Plates are the same density. As they slide by each other in opposite directions, friction causes parts of the plates to combine, creating the mountains.

• The Eurasian Plate is a continental plate and is more dense than the Indian Plate. When the Indian Plate collided with the Eurasian Plate, the Indian Plate subducted below the Eurasian Plate, creating a trench and the mountains.

• The Indian Plate is an oceanic plate and is less dense than the Eurasian Plate. When the Indian Plate collided with the Eurasian Plate, the Indian Plate folded up, creating the mountains.

• The Indian and Eurasian Plates are the same density. When the Indian Plate collided with the Eurasian Plate, both plates folded up, creating the mountains.

Which three observations are caused by plate tectonics?

• Similar fossils are found in Australia, Africa, and Asia.

• Earthquakes occur frequently on the west coast of the United States.

• An ocean current flows northward along the east coast of the United States.

• There is a long string of underwater volcanoes in the Pacific Ocean.

• The sand dunes in the Sahara Desert in Africa move across the landscape.
