BIG IDEAS

Virginia has a wide variety of natural resources.

UNDERSTANDING THE STANDARD

  • Virginia is rich in a wide variety of natural resources, including forests, arable (farmable) land, coal, sand and aggregates (rocks), wildlife and aquatic organisms, clean water and air, and beautiful scenery.
  • A watershed is an area over which surface water (and the materials it carries) flows to a single collection place. The Chesapeake Bay watershed covers approximately half of Virginia’s land area. The other two major watershed systems are the Gulf of Mexico and the North Carolina Sounds.
  • Virginia’s water resources include groundwater, lakes, reservoirs, rivers, bays, and the Atlantic Ocean.
  • Virginia has a great variety of plant and animal resources.
  • Natural and cultivated forests are a widespread resource in Virginia.
  • Virginia’s soil and land support a great variety of life, provide space for many economic activities, and offer a variety of recreational opportunities.

ESSENTIALS

Essential Questions:

·  How do water-related resources in Virginia impact everyday living?

In order to meet this standard, it is expected that students will

  • compare and contrast natural and human-made resources.
  • distinguish among rivers, lakes, and bays; describe characteristics of each; and name an example of each in Virginia.
  • create and interpret a model of a watershed. Evaluate the statement: “We all live downstream.”
  • identify watershed addresses.
  • recognize the importance of Virginia’s mineral resources, including coal, limestone, granite, and sand and gravel.
  • appraise the importance of natural and cultivated forests in Virginia.
  • describe a variety of soil and land uses important in Virginia.

KEY VOCABULARY

aquatic organisms - living things found in water

bay - a large body of water that is surrounded by land on three sides

groundwater - the water beneath the surface of the ground; consists mostly of water that has seeped down

lakes - a body of fresh or salt water surrounded by land

natural resource - things found in nature that can be used by people to satisfy life's needs; water, air, plants, animals, soil, rocks and fossil fuels are examples

reservoir - a large man-made lake where water is collected and stored

rivers - long ribbon-like waterways that usually flow toward an ocean, lake, bay or other river

water-related resources - groundwater, lakes, rivers, reservoirs, bays and the Atlantic Ocean are considered water resources in VA
