Unit 6A test review

Magma wells up and forms a ridge down the middle of the Atlantic Ocean, creating new seafloor that slowly spreads out east and west of the ridge. This is evidence for which of the following theories?

• Earth's crust is made up of rocky plates that move over time

• Earthquakes result from periodic disturbances along fault lines

• Convection currents in the mantle are the cause of volcanic activity

• Magma cooling at the surface of Earth forms a type of igneous rock

Which layers of Earth are mostly made of solid material?

• inner core and outer core

• crust and inner core

• crust and mantle

• mantle and outer core

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

The Hawaiian Islands are in the middle of a large tectonic plate with many volcanoes. The volcanoes are the direct result of the tectonic plate --

• being forced under another tectonic plate at a subduction zones

• colliding with one another tectonic plate and being forced upward

• moving over a hot spot where magma breaks through the crust

• applying great pressure on the crust causing constant earthquakes

On the ocean floor, there are long mountain ranges called mid-oceanic ridges. Which description explains how these geological structures were formed?

• a transform boundary where one ocean plate slides past another ocean plate

• a diverging boundary where two ocean plates move apart from one another

• a converging boundary where an ocean plate sinks beneath a continental plate

• a converging boundary where an ocean plate sinks beneath another ocean plate

• Graph B

A student uses clay to build models of an oceanic plate and a continental plate. What characteristic CANNOT be accurately represented by the models?

• the shapes of plates

• the relative sizes of plates

• the relative densities of plates

• the arrangement of plates relative to one another

Half of a volcanic rock formation can be seen at Pinnacles National Park in California, on one side of the San Andreas Fault. The other half is 195 miles southeast of the park on the other side of the same fault line. This evidence BEST supports which of the following theories?

• Earthquakes are the result of volcanic activity.

• Earth's crust is made of rocky plates that shift over time.

• Rock formations may move hundreds of miles in an earthquake.

• Earth’s current landforms were created when Earth’s surface cooled.

• a ridge

• a trench

• a rift zone
