How do warm water currents affect the coastal areas along which they flow?
They create unusually warm climates for the latitude.
They create less rainfall along the coast.
They create unusually cool climates for the latitude.
They make the coastal climate cooler than the inland climate.
The envelope of gases surrounding the Earth is known as the atmosphere. Which of the following statements
accurately describes the atmosphere?
The atmosphere is composed of masses of air particles that are constantly moving.
The atmosphere is composed of several layers that increase in density as altitude increases.
The atmosphere is composed of masses of particles that move very little, if at all.
The atmosphere is composed entirely of nitrogen and oxygen, which react to form ozone.
Warm, less dense air at the equator
Rises and flows toward the poles
Cools and creates an area of low pressure
Cools and creates an area of high pressure
Cools and then flow toward the poles.
Which condition will most likely lead to the formation of winds on Earth?
Uneven heating of the earth's surface
The shifting of tectonic plates
Geothermal activty
The rotation of the Earth on its axis
Unlike local winds, global winds generally
Blow from specific directions over long distances

Are not influences by heating of the Earth's surface
Change directions from day to day
The transfer of thermal energy by convection is a very important process in the temperature distribution on the surface of the Earth. The term sea breeze describes a thermally produced wind blowing from an ocean surface onto adjoining land.
Water has a higher specific heat than land. Therefore, the temperature of water does not rise as much as landmass.
Land has a higher specific heat than water. Therefore, the temperature of water does not rise as much as landmass.
Land has a higher specific heat than water. Therefore, the temperature of landmass does not rise as much as water.
Water has a higher specific heat than land. Therefore, the temperature of landmass does not rise as much as water.
Which of these would be the best way to measure the effect that removing many trees in the area would have on the hydrologic cycle?
Measure and compare the amounts of precipitation and surface water runoff in the area before and after the trees are removed.
Survey the people living in the area to determine if they use more water before or after the trees are removed.
Measure and compare the speed and direction of wind in the area before and after the trees are removed.
Evaluate the growth of new plants in the area before and after the trees are removed.

convection currents
hurricanes
tornadoes
The Coriolis Effect
Which statement correctly describes one way ocean currents affect a region?
Warm ocean currents keep coastal air temperatures warm, creating moderate climate conditions in coastal regions.
Deep ocean currents move water from polar seas toward the equator, creating drafts of cold air that blow over polar regions.
Cold ocean currents along the equator increase evaporation rates, creating circular winds that produce tropical storms.
Deep ocean currents push into estuaries, creating sand deposits that form barrier islands.
