Most earthquakes and volcanoes occur in areas of the Pacific Ocean called "The Ring of Fire." What is the main reason for this?

• Large numbers of people live in this area.

• That area of the Earth is hotter than any other area.

• Lithosphere plate boundaries are found in that area.

• The weight of the ocean water forces magma to the surface.

What is found in areas on Earth's surface that are located directly above the borders of lithosphere plates?

• Huge deposits of magma

•  Lack of plant or animal life

• Frequent earthquake activity

• Stable and unchanging landforms

What is the MAIN reason that the continents look very different more than they did 100 million years ago?

• Ocean currents have constantly reshaped the continents.

• Volcanoes have made and destroyed many of the continents.

• The continents have drifted apart from one another on lithospheric plates.

• Waves and wind have caused parts of continents to erode into the ocean.
