• convergence

• divergence

• faulting

A student uses clay to construct a model of Earth. Which layer of the model should be the thinnest layer?

• the layer representing the mantle

• the layer representing the outer core

• the layer representing the inner core

• the layer representing the crust

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

The picture shows a model of the internal structure of Earth. Which evidence best supports this model?

• evaluations of seismic data

• direct observations of the layers

• samples of rocks from the layers

• explanations of the rock cycle

• subduction zones

• mid-ocean ridges

• continental shelves

An oceanic plate subducts under a continental plate. Which of these landforms most likely results from the interaction of these plates?

• volcanic mountains

• transform boundaries

• continental shelves

• normal faults

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.

Look at the diagram of a cross-section of the Earth. How does this diagram help to confirm Alfred Wegener’s hypothesis of continental drift?

• It shows that Earth’s mantle has several concentric layers.

• It demonstrates that Earth’s crust is the thinnest of Earth’s layers.

• It illustrates how crustal plates float on convection currents in Earth’s mantle.

• It models how Earth’s core is subdivided into an inner core and an outer core.

The continental crust floats on top of the mantle because the crust is

• less dense than the mantle.

• made of a liquid material.

• made up of oxygen which is a light element.

• separated from the mantle by a layer of water.
