| Question | Answer |
|---|---|
| Earthquake waves are recorded by | seismographs |
| A crack or split in the earth’s crust where the plates have moved is called a | fault |
| The circle of volcanoes around the Pacific Ocean is called the | Ring of Fire |
| Where do most earthquakes occur? | Plate Boundaries |
| What causes earthquakes to occur? | Plates Moving |
| Magma that reaches the surface of the earth is called | Lava |
| What does the Theory of Continental Drift state? | That the continents of the earth are moving on top of the earth’s crust |
| What can earthquakes cause? | Tsunamis, flooding, avalanches, destruction of buildings, damage to roads and railways, and death |
| The ocean where the longest mountain range on earth can be found is | The Atlantice |
| What does the “Theory of Pangea” state? | That the earth’s continents were once all joined together as one large super continent |
| What evidence have they collected that supports the “Theory of Pangea”? | a.) the fossils of dinosaurs b.) the rock layers of continentsc.) the continents look like pieces of a puzzle that fit together |
| What does the theory of Plate Tectonics state? | That the earth’s crust is divided up into plates |
| What created the Hawaiian Islands? | a hot spot located in the plate that allows magma to come up |
| Why does ocean crust get subducted under contintental crust? | It is heavier (more dense) |
| What is a divergent boundary? | two plates pulling apart |
| What is a transform boundary? | one plate sliding past another |
| What is a convergent boundary? | one plate going under another |
| Name a place where a transform boundary is located. | The San Andreas Fault |
| Name a place where one can find an example of a divergent boundary. | The Mid-Atlantic Ridge |
| Name a place where there is evidence of a convergent boundary where two continental plates are colliding. | The Himalayas |
| Name a place where there is a oceanic plate colliding with a continental plate. | All around the Pacific Ocean |
