Virginia Geology What? What can the presence of fossils of different ages tell us about an area? What can the large amounts of sand and gravel in Virginia tell us?

What are the characteristics of the:Coastal PlainPiedmontBlue Ridge Valley and RidgeAppalachian Plateau?????The folding and faulting found in the rocks of the Blue Ridge Mountains ofVirginia were created by

Quick Review Folded and faulted mountains are created by continental plates colliding.

Characteristics of theCoastal Plain erosion and depositionWetlandsRuns from the Fall Line west to the Atlantic Ocean The landscape is terracedFlat area covered with sediments

Piedmont Largest provinceEvidence of dinosaur footprints (trace fossils)

Blue Ridge High ridge separating the Piedmont from the Valley and Ridge (in the middle of the two provinces)Folded mountains

Valley and Ridge Caves underlined with limestone Ancient folded and faulted sedimentary rock Karst layers of rockUnderground streams, caverns, sinkholes

Appalachian Plateau Flat-lying sedimentary rockOldestCoal and natural gas Coal is the most abundant fossil fuel found in Virginia

Review Q: What can the presence of fossils of different ages tell us about an area? A: The many different geologic time periods are represented

Q: What can the large amounts of sand and gravel in Virginia tell us?A: That water once flowed in the area.

Chesapeake Bay Quick FactsSusquehanna River adds largest amount of water into the bay.Animal manure, fertilizer runoff, and sewage treatment plants are all sources of nitrogen and phosphorus in the bayNew York, Maryland, Virginia, Pennsylvania, Delaware, and West Virginia are part of the Chesapeake Bay watershed.

Susquehanna RiverPotomac RiverRappahannock RiverYork RiverJames River

Five major tributaries add water to the Chesapeake Bay. Which tributary adds the largest amount of water to the bay?

Loss of Submerged Aquatic Vegetation in the Chesapeake Bay means following will occur:

There will be a loss of food for animalsThere will be a loss of shelter for animalsThere will be a decrease in oxygen due to a decrease in photosynthesis.

What are some sources of nitrogen and phosphorus in the bay?

Fertilizer runoffSewage treatment plantsAnimal manure

Are power plants a source of nitrogen and phosphorus in the bay??? NO to power plantsThe Chesapeake Bay watershed includes land in six different states. Which of the following states does not drain into the Chesapeake Bay?? VirginiaNew YorkMarylandNew Jersey

New Jersey

Resources and the Environment QuestionsLimestone is a valuable resource in Virginia because it can be used to make?What will requiring the landscape and vegetation be restored of mined lands do?What is the greatest problem caused by the use of wood-burning stoves? What is a point source? Renewable ResourcesRenewable Resources: Solar (sun)geothermalhydroelectricwind

What do you think?What factors affect the cost of a mineral?? How can you conserve nonrenewable resources? Why are some fossil fuels considered to be nonrenewable? Fossil Fuels

Non renewable ResourcesFossil fuels coal, petroleum, natural gas

FactsRecycling materials, developing substitute materials, and reducing waste are all methods of conserving nonrenewable resources.The demand for the mineral by consumers, the supply of the mineral, and the cost of recovering the mineral from the ground all affect the cost of a mineral. Some fossil fuels are considered nonrenewable because they take a long period of time to form.

Limestone is a valuable resource in Virginia because it can be used to make?

ConcreteWhat will requiring the landscape and vegetation be restored of mined lands do?

It will lessen the environmental impact of strip mining.

What is the greatest problem caused by the use of wood-burning stoves?

The smoke from the stove contributes to air pollution.

What is a point source?

A water pollutant that can be traced to a specific source.

A sewage spillRemember the Facts Some fuels are classified as nonrenewable because they?Factors that affect the cost of a mineral are?What are some ways of conserving or protecting resources? Facts againSome fossil fuels are considered nonrenewable because they take a long period of time to form.The demand for the mineral by consumers, the supply of the mineral, and the cost of recovering the mineral from the ground all affect the cost of a mineral. Recycling materials, developing substitute materials, and reducing waste are all methods of conserving nonrenewable resources.

The energy source that depends on Earths internal heat is

Geothermal energy

Windmills Windmills depend on:The speed of the windThe length of the windmills bladesThe efficiency of the windmill

The windmill is an inconsistent source of energy

Solar (sun)What is the major disadvantage of using solar panels to generate electricity? Does solar energy have the least harmful effects on the environment?

Carbon Dioxide Increased levels of carbon dioxide in the atmosphere can be connected to all of the following:Power plant emissionsAutomobile emissionsdeforestation

Advantage/DisadvantageWhat is the main advantage of using dams to produce electrical energy?What is the greatest environmental disadvantage of hydroelectric power?

Solar AnswersThe major disadvantage of using solar panels to generate electricity is that solar panels are affected by cloud coverage and day length. Which of these energy sources produces the least harmful environmental effects?NuclearSolarFossil fuelsHydroelectric

Carbon Dioxide, you answer!Increased levels of carbon dioxide in the atmosphere can be connected to all of the following except?Power plant emissionsAutomobile emissionsDeforestationLoss of the ozone layer

Were you right about hydro?What is the greatest environmental disadvantage of hydroelectric power? Destruction of free-running rivers and their ecosystems

What is the main advantage of using dams to produce electrical energy?They do not produce much pollution Fossil fuels make up over three-quarters of our energy consumption

Acid RainBy increasing the height of smokestacks, industries in the Midwest reduced the local concentration of air pollutants. However, the pollution was carried by wind to the Northeast where it contributed significantly to ACID RAIN.
