Continental/Oceanic
Continental & Oceanic Landforms
| Term | Definition |
|---|---|
| Continental Shelf | The part of the continent located under the water. The width of the continental shelf varies around the edges of the continents. In some places the continental shelf is fairly shallow and in other places it becomes very deep. |
| Continental Slope | The steep slope where the continental shelf drops to the bottom of the ocean floor is called the continental slope. The depth of the ocean water increases greatly here. |
| Mid-ocean Ridge | On the bottom of the ocean, there is a central ridge, or mountain range, that divides the ocean floor into two parts. These underwater volcanic mountains are known as the mid-ocean ridge. |
| Rift Zone | In the center of the highest part of the mid-ocean ridge is a narrow trench called a rift. |
| Trench | There are many steep-sided canyons and deep, narrow valleys in the bottom of the ocean. Ocean trenches are the deepest part of the ocean basin and are deeper than any valley found on land. |
| Ocean Basin/Abyssal Plain | Located on either side of the mid-ocean ridge is the ocean basin. It is made up of low hills and flat plains. This is the deepest part of the ocean floor. |
| Seamount | Underwater volcano |
| Continental Landforms | Physical Features on the Earth's surface |
