| Question | Answer |
|---|---|
| Where do most mountains form? | Plate Boundaries |
| How can you tell a difference between young and old mountains | Old Mountains are rounded and worn down. Newer mountains are steep. |
| What is a group of mountains ranges called? | Mountain Belt. |
| What does weathering and erosion do to mountains? | Causes rock to break down into sediments and then they are carried to other low lying areas. |
| Force that pull rocks apart | Tension |
| Force that pushes or squeezes rock together? | Compression |
| Forces that cause rocks on either side of faults to push in? | Shearing |
| What is the smallest rock fragment from a volcano? | Volcanic Ash |
| A major component of magma? It is made of silicon and oxygen. | Silica |
| What are the main gases in magma? | water vapor and carbon dioxide |
| What is the smaller earthquake that follows a more powerful earthquake in the same area? | Aftershock |
| How many seismograph stations do you need to have to be able to locate the epicenter? | Three |
| What is the fault where rocks are pulled apart? | Normal Fault |
| What is the fault where rocks on either side move in opposite directions? | Strike-Slip |
| What is the fault where rocks are pushed together? | Reverse Fault |
| What is the largest rock fragment thrown from a volcano? | Volcanic Bombs |
| What is fastest moving seismic wave? | Primary (P) waves |
| What type of seismic wave can cause the largest ground movement and the most damage? | Surface Waves |
| If pressure is applied slowly and continental crust crumples, then what forms? | Folded mountains |
| What is the point on the crust where the energy is released? | Focus |
| What is the point on Earth's surface where energy is released? | Epicenter |
| What causes deaths during and earthquake? | Collapsing buildings or other structures |
| How do scientist know the outer core is liquid? | Secondary waves can not travel through it |
| How can volcanoes have positive effects? | Rich, fertile soil for growing crops. Tourist come to mountains and valleys. |
| What does a high content of silica do to magma? | Makes it explosive |
| What can cause volcanoes in the middle of a plate? | Hot Spot |
| The opening at the top of a volcano is called? | Vent |
| Which volcano shape is a broad, flat dome built by gentle lava eruptions? | Shield Volcano |
| Which volcano shape is a steep, cone shaped hill formed by eruption of cinders and other rock fragments that pile up around a single crater? | Cinder Cone Volcano |
| What volcano shape is steep at the top and flattens out at the bottom, its magma is high in silica? | Composite |
| What does the Mercali Scale measure? | Damage to an area from an earthquake |
| Which seismic wave travels a longer distance? | Secondary waves |
| Where do 80% of volcanoes and earthquakes take place? | Ring of Fire |
| A water wave caused by an earthquake, volcanic eruption, or landslide? | Tsunami |
