Unit 4 Review: Part 2

The largest concentration of gas in the atmosphere (78%) is from: oxygen nitrogen carbon argon water vapor Which of these is true of tropospheric ozone? it is "good" ozone it is formed when sunlight interacts with oxygen in the atmosphere it is found in the stratosphere none of these is true of tropospheric ozone Fill in the blanks regarding earth's climate. Earth's seasonal changes are the result of the tilt of the Earth on its axis. When the northern hemisphere is tilted towards the sun, it experiences summer, and the southern hemisphere experiences winter. During this June solstice, the northern hemisphere experiences the longest day of the year. When the sun is overhead at the equator, there is equal distribution of the sun on both hemispheres, and they experience fall or spring. Albedo and Surfaces Sort the different surfaces into low or high albedo categories. Low Albedo forest asphalt High Albedo snow ice Weather Cells Label the different weather cells on the diagram. Hadley Cell Ferrel cell Polar cell Weather Cells Part Two Sort the characteristics into the appropriate cells. Hadley cell tradewinds tropical rainforest heated air rises and spreads out Ferrel cell westerlies evergreen forest Polar cell suppressed precipitation lots of ice Which statement is not true regarding the Coriolis effect? faster rotation speeds found closer to equator cause objects that are moving directly north or south to deflect winds do not travel straight because of the rotation as Earth rotates, its surface moves much faster at the poles than at mid-latitude and equatorial regions all of these are true regarding the Coriolis effect all of these are not true regarding the Coriolis effect Rain Shadows A rain shadow is a region with dry conditions found on the leeward side of a mountain range as a result of humid winds from the ocean causing precipitation on the windward side. On the windward side, air rises, cools, and forms clouds, leading to large amounts of precipitation. On the leeward side, the cold, dry air descends, warms via adiabatic heating, which leads to the drier conditions. Ocean Currents Name THREE things that drive ocean currents. Upwellings What is the purpose of an upwelling? Thermohaline Circulation Explain, in your own words, what thermohaline circulation means, and why it is a crucial process. Which of these explains what happens in an El Nino year? trade winds push warm surface waters away from west coast of South America and promote upwelling of water from ocean bottom trade winds weaken or reverse direction, so warm waters build up along west coast of South America there are unusually cold temperatures in the northern US and more rain than usual in the northern hemisphere there is cooling of water in the equatorial Pacific Ocean
