Earth’s Natural Resources, Energy, & The Environment
Review for Exam
Earth Spheres
• How are the Earth’s Spheres affected by the extraction of Earth’s natural resources?
• For example: Surface mining for coal, drilling for oil.
• How are the Earth’s Spheres affected by the use of various energy resources? For example: How does a hydroelectric dam affect each Earth Sphere?
Renewable/Nonrenewable Resources
• Understand and state the difference between a renewable and nonrenewable resource.
• List and distinguish between examples of renewable and nonrenewable resources and energy sources.
From Sun to Energy
• Be able to describe the process in which the energy consumed today came directly or indirectly from the sun.
• Describe the process of Sunlight to Energy for each of the following energy sources:
• Coal• Oil/Natural Gas• Wind• Hydroelectric
Benefits and Drawbacks
• Be able to describe the BENEFITS and DRAWBACKS for each energy source described in class. BE SPECIFIC!
• Remember, stating that burning coal “pollutes the air” or “causes pollution” is not specific enough.
• Burning coal releases gases like CO2, NOx, and SOx into the atmosphere. CO2 is a greenhouse gas and NOx and SOx contribute to Acid Rain.
Fossil Fuel Consumption
• Recognize current United States trends in consumption and production of oil, coal, and natural gas.
Compass Direction/Degree Orientation
• Using a protractor, be able to draw compass bearings based on degree orientation.
• Problem: Match the compass directions below to the appropriate degree orientation.
• •
North 270°East 0°/360°South 90°West 180°
Slope Calculations
• Given the elevation of two points and the distance between those two points; be able to calculate the slope of a hillside or mountain.
• Example:– Point A elevation = 1000 feet– Point B elevation = 500 feet– Distance from Point A to Point B = 250 feet• Rise ÷ Run X 100 = % slope
Wind Turbine Site Factors
• Identify and describe factors to consider in determining the potential location of a wind turbine.
• Wind resource availability• Terrain analysis • Relief• Slope• Terrain orientation (North, south,
east, west)
