| What is the difference between oceanic and continental crust? |
|
Definition
| Oceanic crust is thinner and denser than continental crust. |
|
|
Term
|
Definition
| This is a supercontinent that existed over 300 million years ago in which all the current continents were fit together in one large land mass. |

|
Definition
|
|
Term
|
Definition
| This is what the tectonic plates are made of - it is the crust and the top-most part of the mantle. |
|
|
Term
| What causes Earth's tectonic plates to move? |
|
Definition
| Very slow moving convection currents in the mantle push the plates. |
|
|
Term

|
Definition
Any of these would work.
1.Similar mountain formations on different continents
2. Similar rock deposits and formations on different continents
3. The close fit of continental coastlines
4. The matching glacial groves on different continents |

|
Definition
|
|
Term
| Where do earthquakes occur? |
|
Definition

|
Term
| What is the name of the tube that connects a volcano's magma chamber to the Earth's surface? |
|
Definition
| Pipe - also called a conduit |

|
Definition
|
|
Term
| Describe composite volcanoes |
|
Definition
| These are tall, cone-shaped mountains which have layers alternating with lava and ash. |
|
|
Term
| Describe shield volcanoes |
|
Definition
| These have gently sloping sides made of layers of thin, runny lava. |
|
|
Term
| Describe cinder-cone volcanoes |
|
Definition
| These generally have sharply sloping sides made mainly of violently erupted pyroclastic material. |
|
|
Term
| What is the main difference between magma and lava? |
|
Definition
| Magma and lava are both melted, molten rock material but magma is below the surface of the Earth and lave is above the surface of the Earth. |
|
|
Term
|
Definition
| The area below the volcano that contains molten rock material. |
|
|
Term
| What is a volcano conduit? |
|
Definition
| This is another name for a volcano's pipe - it is the tube that connects a volcano's magma chamber to the Earth's surface |
|
|
Term
| Where is the Ring of Fire? |
|
Definition
| This is a long series of volcanoes located around the borders of the Pacific Ocean and its surrounding continents. |
|
|
Term
| What caused the Volcanoes that make up the Ring of Fire to form? |
|
Definition
| The convergent boundaries of two tectonic plates moving toward each other in which the oceanic plate is subducted under the continental plate. |
