The basic source of energy for all earth systems is… The Sun
Matter with a high thermal energy will also have a high… Temperature
Cold water is __________ dense than warm water and will __________ More; Sink
Cold air is __________ dense than warm and and will ____________ More; Sink
Warm water is __________ dense than cold water and will __________ Less; Rise
Warm air is ___________ dense than cold air and will ________ Less; Rise
This method of heat transfer relies on direct contact between matter. Conduction
If my hand touches a hot stove, I will get burned due to this method of heat transfer. Conduction
This method of heat transfer occurs due to differences in a fluid's (liquid or gas) density Convection
This method of heat transfer can occur across empty space Radiation
If I stand outside and feel the sun's heat, I am experiencing this method of heat transfer. Radiation
What 3 factors affect surface currents in the ocean? Wind, Coriolis Effect, Continental Deflection
What 2 factors determine the density of ocean water? Temperature and Salinity
What causes a convection current to occur in air and water? Differences in density
Which 3 gases are most abundant in earth's atmosphere? Nitrogen, Oxygen, and Carbon Dioxide (N, O, and CO2)
Which gas is most abundant in earth's atmosphere? Nitrogen
List the layers of the atmosphere from closest to earth to farthest. Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
Which layer of the atmosphere contains ozone (O3)? Stratosphere
What is the main benefit of ozone? It filters out ultraviolet (UV) radiation, which can cause sunburns and skin cancer.
List three greenhouse gases. Carbon Dioxide, Methane, and Nitrous Oxide.
Which greenhouse gas is being added to the atmosphere in dangerous amounts by humans? Carbon Dioxide (CO2)
What causes the Coriolis Effect? Rotation of the Earth
This wind belt blows from to poles in an east to west direction. Polar Easterlies
This wind belt blows in the mid-latitudes from west to east. Prevailing Westerlies
Which breeze forms during the day when land heats up faster than water? Sea Breeze
Which breeze forms at night when land cools down faster than water? Land Breeze
True or false: Valleys heat up and cool down faster than mountains. False: Mountains heat up and cool down faster than valleys.
True or false: A mountain breeze forms in a valley and travels up a mountain. False: A Valley Breeze forms in a valley and travels up a mountain. A mountain breeze forms on a mountain and travels down into a valley.
Air currents (wind) move from… High pressure to low pressure, and cold temperatures to warm temperatures.
Which fuel used by humans dangerously increases the greenhouse gases in the atmosphere? Fossil Fuels such as coal, oil, gasoline, and natural gas.
