SUPERQUIZ 5
SuperQuiz Section 5, pp 40-47
| Question | Answer |
|---|---|
| What are the three major atmospheric loops or "cells" that create winds that blow from high pressure areas to lows, then high up again? | Polar cell, Ferrel cell, Hadley cell |
| In what climate zone is the Hadley cell found? | the tropics |
| What do airline pilots flying across the Atlantic sometimes use to give themselves a speed boost when flying eastward? | the jet stream |
| The giant, vertical loops in which the atmosphere moves are known as what? | cells |
| In what climate zone is the Ferrel cell found? | the temperate zone |
| In what climate zone is the Polar cell found? | the polar zone |
| the wind blowing most of the time is known as what? | the prevailing wind |
| The satellite Aeolus monitors what aspect of Earth's weather? A) ocean currents B) cloud cover C) global wind circulation D) temperature variations E) storm surge levels | C) global wind circulation |
| Which of the three major global cells is the weakest? | the Polar cell |
| Which of the three major global cells is driven by strong Sun at the equator? | the Hadley cell |
| The easterly winds that blow through the tropics are known as what? | the trade winds |
| What is the name for the wavy band around the world where the trade winds from north and south meet? | the Intertropical Convergence Zone (ITCZ) |
| Dusty skies in the summertime in the southeastern United States are caused when the trade winds pick up dust from where? | the Saharan desert |
| In the ITCZ sailors can be stuck for days because the winds are not blowing. Where is all the air going? | directly up |
| What is another name for the ITCZ? A) the doldrums B) the pot au noir (the black pot) C) the trade winds D) all of the above E) both A and B | E) both A and B |
| Because the ITCZ has ferocious updrafts that can create giant thunderclouds or waterspouts, sailors sometimes call it by this name. | the pot au noir (the black pot) |
| The trade winds blow toward ________________. A) the tropic of cancer B) the tropic of Capricorn C) the equator D) the international date line E) the arctic circle | C) the equator |
| Although the trade winds blow toward the equator, they don't blow directly northward or southward because of what? A) the ITCZ B) Earth's gravitational pull C) the Hadley cell D) Earth's rotation E) the doldrums | D) Earth's rotation |
| What do scientists believe is the cause of rains in the Amazon rain forest beginning 2-3 months before moisture brought by the trade winds arrives? A) the movements of the ITCZ B) the trees of the rainforest release enough moisture to create clouds and rain C) an El Nino event D) global warming E) they don't know why this happens | B) the trees of the rainforest release enough moisture to create clouds and rain |
| In what direction does the Walker cell circulate? | east-west |
| What drives the trade winds in the Indian Ocean and southern Pacific - the Hadley cell or the Walker cell? | the Walker cell (this one is tricky - look at page 43) |
| From what direction do the prevailing winds blow in the polar regions? | from the east (the polar easterlies) |
| The polar easterly winds are created by the spinning of the Earth and the __________. A) ITCZ B) trade winds C) Hadley cell D) Coriolis force E) none of the above | D) Coriolis force |
| What sort of weather do the polar easterlies bring most of the time? A) clear, bright days and icy nights B) heavy snow C) a bomb cyclone D) sleet and hail E) heavy cloud cover but no rain | A) clear, bright days and icy nights |
| Which of the following best describes the polar easterlies? A) warm and unsettled B) fast moving with a lot of moisture C) dry and bitterly cold D) warm and dry E) cold with heavy snow | C) dry and bitterly cold |
| In the polar regions the air is so cold and dense that it can only sink, creating a(n) _____________________. A) high pressure zone B) low pressure zone C) polar vortex D) occluded front E) bomb cyclone | A) high pressure zone |
| What major cell drives the westerly winds? | the Ferrel cell |
| The zone where the westerlies start, about 30 degrees N, are sometimes called the ________________________. | horse latitudes |
| In the "horse latitudes", air from both the ______ cells and ________ cells descends. | Hadley and Ferrel cells |
| Why is Ireland sometimes called "the Emerald Isle"? A) it has many large and famous emerald mines B) because shamrocks are the same color as emeralds C) because its abundance of rainfall makes its grass very green D) because it is well-known as the birth place of St. Patrick E) because barely a day goes by without any rain | C) because its abundance of rainfall makes its grass very green |
| Which of the following is the biggest single influence on weather across all of the US, except the deep south? A) the polar front B) easterly winds C) the jet stream D) Ferrel cells E) atmospheric rivers | A) the polar front |
| Why do the zones between 40 degrees and 70 degrees in the southern hemisphere have nicknames such as "roaring forties" and "screaming sixties"? A) because the winds here often sound like wild animals B) because there are many shipwrecks in these latitudes C) because the westerly winds are largely uninterrupted here and blow very strong and fast D) because of the legend that sailors used to toss their horses overboard here E) because drinking water supplies often run low here, leading to parched throats | C) because the westerly winds are largely uninterrupted here and blow very strong and fast |
