Sci 8 Plate Tectonics

Mountains form from....

• Plates sliding past one another
• collision of plates
• plates moving away from each other
• none of these

Earth's plates are....

• Constantly moving and changing the face of the Earth
• Never moved
• Move seldom and very fast
• move when they feel like it

What was the name given to all the continents when they were joined as one super continent?

• Supreme Continent
• Eurasia
• Plate tectonics
• Pangea

Is there a pattern to the locations of earthquakes and volcanoes around the globe?

• No, earthquakes and volcanoes are random.

• Yes, earthquakes and volcanoes usually occur near the boundaries of tectonic plates.

• yes, earthquakes and volcanoes usually occur in the middle of tectonic plates.

• No, earthquakes and volcanoes usually occur under water.

Most earthquakes tend to occur at which location?

• The central regions of very large continents

• Groups of islands farthest from any continents

• The boundaries between continents and oceans

• The steep slopes of the very oldest mountains

Tectonic plates:

• can move towards each other

• can move away from each other

• can slide past each other

• All of the above
