| Question | Answer |
|---|---|
| What are the 3 types of faults? | Normal, Reverse and Strike-Slip |
| What is a normal fault? | forms when the hanging wall drops down. One side goes down and one side goes up. |
| What is a Reverse fault? | A reverse fault is just like a normal fault because they one side goes up and one side goes down, however in a reverse fault, the up side hangs over the down side. |
| What is a Strike- Slip Fault? | walls that move sideways, not up or down. |
| What are the 3 types of stress? | Shearing, compresion, and tension |
| What is Shearing? | A force that pushes two rocks in 2 opposite directions. Causes rock to break slip or change shape. |
| What is Compression? | A force that pushes two rocks together. Causes crust to rise creating land forms such as mountains. |
| What is tension? | A force that pulls on rock in opposite directions |
| What is a hot spring? | forms when groundwater heated by a nearby body of magma rises to the surface and collects in a natural pool |
| What is a geyser? | is a fountain of water and steam that erupts from the ground |
| What are the parts of volcano | lava, magma, magma chamber, side vents, vent, pipe, crater, lava flow |
| What are the types of volcano eruptions? | pyroclastic flow, Aa. , Pahoehoe |
| What is a pyroclastic flow? | when the magma is thick and sticky, a volcano will erupt explosively; occurs when the magma becomes trapped in the volcano’s pipe and pressure builds up until it explodes |
| What is a Aa flow? | Cooler and slow moving, more silicon |
| What is a Pahoehoe flow? | Hotter and faster moving, less silicon |
| What are the stages if a volcano | Active, dormant, extinct |
| What is an active volcano? | when a volcano is either erupting or most likely going to erupt in the near future. |
| What is a dormant volcano? | scientists expect a dormant volcano to awaken in the future and become active |
| What is an extinct volcano? | A volcano that does not erupt anymore and most likely never will in the future. |
