• To show the Aleutian Trench
• To show the Equator
• To show the Ring of Fire

2) What possible technique could scientists have used to create this map of the ocean ridges?

• observing from underwater vehicles
• monitoring sound waves
• surveying land levels
• comparing mountain ranges

3) Which shows the elevation of an area using contour lines?

• mountains
• topographical maps
• cartographer
• faults

4) Which type of map would best help a scientist study where earthquakes and volcanoes occur most often?

• Political map
• Topographic map
• Weather map
• Road map

5) Which best describes how earthquakes and volcanoes shape the land?

• They break down the land.
• They build up the land.
• They can destroy things, but they can also build up the land.
• Only weathering and erosion can change the land.

6. Based on the earthquake map below, which statement BEST describes the data in the map?

• Earthquakes occur in random locations.
• Most earthquakes occur in the Southern Hemisphere.
• The strongest earthquakes occur near the middle of oceans.
• Most earthquakes occur along boundaries between continents.

7) Look at the map of continental plates. What do you notice about the locations of earthquakes and volcanoes in relation to plate boundaries?

• Most earthquakes and volcanoes happen near plate boundaries.
• Earthquakes and volcanoes only happen in the middle of continents.
• There are no earthquakes or volcanoes near plate boundaries.
• Earthquakes and volcanoes happen randomly with no pattern.

8) Why do earthquakes usually occur near plate boundaries?

• Earthquakes are caused by hot magma under the Earth's crust.
• Earthquakes occur randomly all over the world.
• Earthquakes happen due to the rotation of the Earth.
• Earthquakes result from the movement in Earth's techtonic plates.
