The student will investigate and understand important Virginia natural resources. Key concepts include a) watershed and water resources; b) animals and plants; c) minerals, rocks, ores, and energy sources; and d) forest, soil, and land.
1. resource - something we need, want, and use (example: water, food)
2. natural resource - a resource that comes from the earth (made by nature) (example: tree, soil, water,
plants, animals, sun) It helps support life on earth
3. cultivated resource - a resource created by man (example: planting trees)(man-made)
4. renewable resource - a resource that can be replaced in a short period of time
5. non-renewable resource - a resource that cannot be replaced in a short period of time
6. agriculture - farming/raising (example: corn, pigs) Virginia’s largest industry
7. arable - good (as in soil), fertile
8. aggregates - rocks
9. ecosystem - living and nonliving things in an environment and all their interactions
10. niche - the role of an animal/plant in its environment
11. extinct species - animals/plants that have died out/ no more species of that kind are on earth
12. endangered species - animals/plants that are very close to becoming extinct/ only a few left
13. threatened species - animals/plants likely to become endangered/extinct
14. exotic species - a plant/animal new to an area
15. over-harvesting - taking more plants/animals than the population can withstand
16. habitat loss - animals/plants losing their homes (caused by pollution, destroying homes, over hunting)
17. watershed - an area of land where all water (H20) under it or draining off of it goes into a common
body of water
18. aquatic - having to do with plants/animals in the water
19. precipitation - water to the earth in the form of rain, snow, sleet, hail
20. drought - caused by below average precipitation (not enough water)
21. flood - too much water
22. estuary - a place where fresh water and salt water mixes
23. hydropower - electrical power produced when water is captured at a dam or created by falling water
24. reservoir - a human-made lake that stores water held back by a dam
25. surface water - water within the earth that supplies wells and springs
26. groundwater - water that comes from the ground
27. sediment - material, such as stones and sand, deposited by water
28. mineral - a naturally occurring substance, neither plant nor animal
29. ore - a mineral containing a useful substance that is mined from Earth
30. conservation - the act of saving, protecting, or using resources wisely
31. pollution - adding harmful substances to the air, water, and land
32. reduce - use smaller amounts of a natural resource (example: take showers, not baths)
33. reuse - use a resource over and over again (example: make a pencil holder from a can)
34. recycle - turn in plastic, glass, or cans to be used again
1. Virginia is rich in a wide variety of natural resources.
2. natural resources: a material found in nature that is useful to people
3. man-made resource: things made by people out of materials that began as natural resources
4. Virginia’s water resources include
5. Virginia has many rivers, lakes, and bays.
6. A watershed is an area over which surface water (and the materials
it carries) flows to a single collection place. There are 14 watersheds
in Virginia; 9 of them are major ones.
1. The Chesapeake Bay watershed covers half (50%) of Virginia’s land area.
2. The other two major watershed systems are the Gulf of Mexico and the North Carolina Sounds.
7. The nine major watershed “addresses” in Virginia are the:
1. Potomac-Shenandoah Rivers Watershed
2. Rappahannock River Watershed
3. York River Watershed
4. James River Watershed
5. Eastern Shore of Chesapeake Bay &
6. Chowan River Watershed
7. Roanoke River Watershed
8. New River Watershed
9. Tennessee-Big Sandy Watershed

9. Natural and cultivated forests are a widespread resource in Virginia.
10. Virginia contains several important mineral resources.
