Question | Answer |
---|---|
What is a plain | A generally flat area of land that can sometimes vary slightly in elevation; generally good for farmland or urban development |
What is a plateau | A large flat area at a higher elevation |
What is mountain | An area that has a higher elevation; generally found near the boundary of where tectonic plates meet. |
How is a plateau formed? | An upward movement of the earth, causing a large flat area to rise to a higher elevation. |
What divergent boundaries? | Areas where tectonic plates spread further apart; sometimes results in molten lava coming up. |
What is a fold mountain? | When plates converge, one plate moves under the other, causing the other plate to rise higher. This results in creating areas of higher elevation. |
How can you tell if a mountain is old. | Due to erosion, those mountains will appear worn down over time; elevations will be generally lower and land will appear less jagged and rough. |
When you look at images of land from a "lidar" how can you tell if a landslide occurred recently? | The images will appear dark and the edges of land where the landslide took place will appear well-defined and sharp. |
When you look at images of land from a "lidar" how can you tell if a landslide occurred a long time ago? | The images will appear lighter and the edges of land where the landslide took place will appear smooth and perhaps blurry. |
What is the Ring of Fire? | An area that is prone to tectonic shifts that is closely associated with volcanic activity and earthquakes. |
What is the Richter Scale used for? | A standard of measuring the strength of an earthquake based on its effects and the damages it causes. |
