Tectonic Plates

Tectonic Plates

Multiple Choice

What causes the tectonic plates to move?

• convection of magma
• the earth's magnetic field
• the earth spinning
• earth's gravitational pull

Multiple Choice

Scientists think that the movement of Earth's tectonic plates are caused by convection currents, that are located in the _________?

• outer core
• inner core
• mantle

Multiple Choice

Which set of events is most common along tectonic plate boundaries?

• Earthquakes and volcanoes

• Erosion and earthquakes

• Tidal waves and volcanoes

• Hurricanes and tsunamis

Multiple Choice

How are faults that occur in the middle of tectonic plates different from plate boundaries?

• Plate boundaries are sites for earthquakes but faults are not.

• Plate boundaries occur between tectonic plates while faults can occur anywhere.

• Faults cover larger areas than the intersections between plates.

• Faults are the sites of volcanoes while the intersections between plates are not.

Multiple Choice

One student of a class studying where earthquakes and volcanoes occur says that geologists cannot predict earthquakes. Which of the below statements contradicts the student’s conclusion?

• Earthquakes are caused by changing weather conditions.

• Earthquakes can occur in every state in the United States.

• Earthquakes are statistically more common around fault lines.

• Earthquakes are caused by landslides occurring at Earth’s surface.

Multiple Choice

Earth's crust is broken up into several large rocky pieces called ...

• plates
• faults
• fossils
• puzzle pieces

Multiple Select

Convection currents happen in the mantle. The outer core heats magma around it and causes it to become less dense. Because the magma is less dense than the material around it, it starts to rise toward the crust. Since the crust is not hot, the magma starts to cool as it gets close to the crust. Since it is cooling, it gets denser and starts to sink back down toward the outer core.

Use the information above to answer the following question: Which of the following TWO things happen to magma causing it to rise?

• It gets cooler.

• It gets warmer.

• It gets denser.

• It gets less dense.

Multiple Choice

Multiple Choice

Which layer of the Earth is solid iron and nickel?

• Mantle

• Crust

• Inner Core

• Outer core

Multiple Choice

Describe the most likely relationship between these mountains and nearby tectonic plates.

• The mountains are probably formed by earthquakes

• The mountains are probably formed by the movement of glaciers

• The mountains are probably located near the edge of 2 tectonic plates.

• The mountains are probably formed by running water.
