What is the indication on a topographic map that the slope is steep? gentle?
Steep = lines close together; Gentle = lines are farther apart

The fossil fuel found in the greatest abundance in Virginia is _______________. Where do we find it in Virginia?
coal and in the Appalachian Plateau
100
What is the most abundant mineral on Earth?
Quartz = SiO2
200
If you have a graduated cylinder that starts with 45 mL of water and you add a mineral and the volume changes to 100 mL, what is the volume of the mineral?
55 mL Volume displacement - remember you SUBTRACT the 2 values
200
What happens during convection?
Warm air rises and cold air sinks - Remember this is due to DENSITY differences - all weather is driven by convection
200
What is another word for lines of longitude? Are they parallel or not?
Meridians and no - they meet at the poles

Determine the problem, make a _____________, test the hypothesis, _______________________ and draw a conclusion.
hypothesis; analyze results
300
A cold front would bring what type of weather?
Some form of precipitation and a drop in temperature
300
Line of latitude run which way? What is the range for lines of latitude?
Lat is fat - they run east to west but measure north to south of the equator = 0 degrees; North or South Pole = 90 degrees so 0 - 90 degrees N and S
300
What is a major disadvantage of using fossil fuels? What is disadvantage of using wind energy? Where in Virginia would wind energy be usable? What is one form of energy that has not been explored fully in Virginia?
fossil fuels pollute; wind energy is not consistent; wind energy could be used in the Highlands or Coastal Plain; tidal energy

The symbol " L " on a weather map indicates what? What instrument is used to measure this phenomenon?
L = low pressure; a barometer ; Remember low pressure usually brings BAD weather
400
Lines of longitude run which way? What is the range of measurement for lines of longitude?
Longitude lines run north to south but measure east or west of the Prime Meridian (in England) = 0 degrees; International Date Line = 180 degrees; Range of measurement = 0 - 180 degrees E/W

What is the difference between a law and a theory?
A law is quantifiable - involves numbers and formulas; A theory is more qualitative - descriptions without formulas
