  2. What are the renewable and non-renewable natural resources in Maryland? How do we use what we have to meet our needs?

  4. Soil Soil provides the minerals and nutrients that plants need to live. We Marylanders eat those plants in order for us to survive. Soil can be damaged in many ways. Even though it is a renewable resource, we still need to carefully maintain it.

  5. Farmland Did you know that Maryland has 2 million acres of farmland? • Maryland farmers grows corn, soybeans, winter wheat and barley for resale. • Grapes are fast becoming a cash crop as well. Beets, Greens, and Gourds do well in our soil and climate too. Watermelons and strawberries fit our growing season too.

  6. Hogs, pigs, cows, sheep, chickens and turkeys all need responsible farmers to raise them. On the farm.. From the chickens-we utilize the eggs and then eventually the bird itself. Cows provide us with many dairy products as well as meat. Swine provide us with a variety of meat products. We use their coats to make cloth.

  7. The Chesapeake Bay Did you know that our Chesapeake Bay is the largest estuary in the United States? The Bay is home to over 300 varieties of crustaceans, aquatic plants, insects and fish. The Chesapeake Bay is over 200 miles long. The word Chesapeake means “great water” in Algonquian, a native tribe of this area. The surrounding wetlands are home to even more varieties of wildlife.

  8. Aquaculture on the Bay • Our Bay and its tributaries “farm” tilapia, catfish, crawfish, trout, oysters and soft crabs for resale around the world. • 85% of our total resale aquaculture consists of what is commonly referred to as “ornamentals”. “Ornamentals” are organisms like goldfish, bay grasses and koi. Aquaculture is farming of the water.

  9. Forests • Forestry is the 5th largest industry in Maryland. • We supply lumber (for construction), pulpwood (for making paper and “Green” energy) and piling (chemically treated wood using for the making of foundations). pilings pulpwood

  10. Geothermal Energy This geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, and from solar energy absorbed at the surface. It has been used for space heating and bathing since Ancient Rome, but is now better known for generating electricity.

  11. Can you guess which elementary school in Prince George’s County has a geothermal heating and cooling system? • Vansville Elementary in Beltsville. There is a Geothermal Room located in the building which serves as a control room for the 3 high tech systems located near the school building.

  12. Biomass • Biomass refers to plant matter grown to generate electricity or already produced trash such as dead trees and branches, yard clippings and wood chips. • Industrial biomass can be grown from numerous types of plants, including corn, poplar, sugarcane, and a variety of tree species.

  13. Wind • We convert wind energy into electricity or just use it directly. • Wind “farms” in Maryland are located in the mountain region of Western Maryland and a few on the Eastern Shore. Wind farms

  14. Solar • We use this infinite resource in 3 ways: • passive solar heat • active solar heat • Photovoltaics (solar cell) Photovoltaics (solar cell) uses the light produced by the sun (or any light source) to generate electricity directly. Sunlight striking a photovoltaic causes a voltage and current to be created in a semiconductor that can be used just like the electrical energy from a battery. The first two energy sources involve collecting the heat produced by the sun for use in heating living or working space, or hot water.

  17. Non-Renewable Resources in MD • Coal • Natural Gas • Rocks and Minerals

  18. Coal 57% of MD’s electricity is produced from coal! • Coal is a fuel. • It can be burned to make useful heat or energy. • Burning coal causes water to turn to steam, which causes generators to spin and make electricity. Western MD has 2 underground and 14 surface coal mines.

  19. Natural Gas • Made from fossils-called a fossil fuel • Found in porous rocks Garrett County, Allegany County

  20. Rocks and Minerals • Maryland uses and sells crushed stone, cement, construction sand and gravel and various clays. Quarry in Savage, MD Laurel Sand & Gravel- Laurel, MD Crushed Stone
