Plate tectonics, earthquakes and volcanoes Review

Earth's solid, rocky surface is the 

• crust
• mantle
• core
• fault

What is represented by the picture? 

• Sea-floor spreading
• Pangea
• How the continents are arranged today
• Volcanoes

Look at the image. The South American and Nasca plate are moving together. Which type of boundary is this? 

• divergent
• convergent
• transform fault

In the image, which type of boundary is shown? Hint: its located in the state of California. 

• divergent
• convergent
• transform fault

Which type of event often occurs along transform fault boundaries? 

• volcanoes
• earthquakes
• sea-floor spreading
• mountain building

The image shows a dormant volcano. These types of volcanoes are the most explosive and grow to be very tall. Which type of volcano is this?

• shield volcano
• cinder cone volcano
• composite/stratocone volcano

If the focus of an earthquake occurs beneath the sea floor, as the seismic waves travel through the ocean, they create a massive and destructive

• epicenter
• tsunami
• focus
• mountain

When molten rock reaches the Earth's surface, comes out and begins to cool, it is known as

• lava
• mantle
• magma
• crater

What is the main cause of most earthquakes?

• human activity
• hurricanes
• changes in temperature in Earth's mantle
• pressure deep within the Earth (from rocks crashing) that is being released

The movement of Earth's crust along plate boundaries produces

• earthquakes
• volcanoes
• moutains
• All of these options.
