| A | B |
|---|
| What do you call people who study the Earth? | Geologists |
| What do you call people who study earthquakes? | Seismologists |
| The place where two plates come together is called a(n) | Fault |
| What process makes the hot rocks rise and reach the surface? | Convection (hot fluids rise) |
| What was the name for Wegener's super continent? | Pangaea |
| What did tropical plant fossils found at the South Pole show? | The south pole used to be where it was very warm |
| What kind of plate motion is where two plates slide by each other side by side? | Transform boundary |
| What is the correct order for the layers of the Earth from the surface down? | Crust, Mantle, Outer Core, Inner Core |
| Where are volcanoes MOST likely to occur? | At the edges of plates |
| Lava with high viscosity will travel very ... | Slowly (viscosity means resistance to flow) |
| What force keeps plates from sliding until an earthquake occurs? | Friction |
How far away is an epicenter if it takes 6 minutes to reach a seismograph station?,  | between 4,200 km and 4,400 km |
| What is it called when one plate slides under another? | Subduction |
| What device measures the magnitude (size) of earthquakes? | Seismometer or seismograph |
| What is the part of the Earth that is the crust and the upper part of the mantle? | Lithosphere |
| The asthenosphere is part of what layer of the Earth? | Mantle (where the rocks are gooey) |
| In what layer would you expect the pressure to be the greatest? | Inner Core |
| Which layer of the Earth is the thickest? | Mantle |
| Which layer of the earth is a hot, dense ball of metal? | Inner Core |
| What is the process called where people take heat out of the Earth to heat their homes? | Geothermal (Geo = Earth and Thermal = heat) |
| What is the name for the process where hot fluids rise and cold fluids sink? | Convection |
| What is the name for how fast fluids flow? | Viscosity (high viscosity means slow flowing - like molasses with sand) |
| What makes hot rocks in the mantle rise to the surface and move plates? | Convection |
| What do you call scientists who study volcanoes? | Volcanologists (pronounce vul' can ahl og ists) |
| When plates come together, what kind of motion is that? | Convergent |
| What is the thickest layer of the Earth? | Mantle |
| Do transform faults usually have volcanoes? | No (the earth doesn't open up and the San Andreas fault does not have earthquakes) |
