| Term | Definition |
|---|---|
| Continental Shelf | the shallow, gently sloping, submerged extension of a continent, typically stretching from the shoreline to a depth of about 100–200 meters (approx. 60–600 feet) |
| Continental Slope | the slope between the outer edge of the continental shelf and the deep ocean floor. |
| Sediments | accumulated layers of organic and inorganic particles—such as sand, mud, silt, and skeletal remains—that settle onto the seafloor |
| Continental Rise | a wide, gently sloping underwater feature found at the base of the continental slope, typically at depths of 3,000 to 4,000 meters |
| Abyssal Plain | a vast, incredibly flat, and nearly level area on the deep ocean floor, typically found at depths between 3,000 and 6,000 meters (approx. 10,000 to 20,000 feet) |
| Deep Sea Trenches | re long, narrow, steep-sided depressions on the ocean floor that mark the deepest parts of the ocean, often exceeding 20,000 feet (meters) in depth. They form at convergent plate boundaries |
| Lakes | large bodies of still freshwater (examples: Lake Drummond, Bark Camp Lake) |
| Rivers | Bodies of flowing freshwater (James River and Clinch River) |
| Bays | an area of saltwater mostly surrounded by land (Chesapeake Bay) |
| Ocean | a large body of saltwater (The Atlantic Ocean) |
| Watershed | an area of land over which surface water flows to a single collection plate |
| Natural Resources | are resources that occur naturally, meaning that they can exist without humans. They are used to aid human life |
| Man Made Resources | resources that are created by humans |
| Capital Resources | goods used to make other goods or services |
