WORLD GEO CHAPTER 3 TEST 3

Different places on Earth receive different amounts of direct sunlight at the same time

• because volcanic eruptions cloud the sky

• because of climate variations

• because the greenhouse effect blocks the sun's rays

• because earth is tilted on its axis

About ow long does it take for Earth to complete a revolution around the sun?

• 7 days

• 31 days

• 365 days

• 1,00 days

Which of the following statements accurately describes the relationship between the Tropic of Cancer and the Tropic of Capricorn?

• The Tropic of Cancer is north of the Tropic of Capricorn.

• The Tropic of Cancer is south of the Tropic of Capricorn.

• The Tropic of Cancer is east of the Tropic of Capricorn.

• The Tropic of Cancer is west of the Tropic of Capricorn.

How does the Coriolis effect influence winds?

• It causes them to blow to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• It causes them to blow to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.

• It causes periodic El Niño episodes

• It causes them to become still, resulting in the doldrums

What is the equinox?

• a day on which the sun is directly over the Tropic of Cancer

• a day on which the sun is directly over the prime meridian

• a day on which the sun is directly over the Equator

• a day on which the sun is directly over the Tropic of Capricorn

The rain shadow effect causes

• hurricanes to develop in the atlantic ocean

• dry areas to develop on the leward sides of mountain ranges

• ice caps to develop on the north side and south poles

• monsoons to develop in the Pacific Ocean

El Nino is a phenomenon that originates in

• the pacific ocean

• the atlantic ocean

• the caribbean sea

• the mediterranean sea

The term Permafrost refers to

• glaciers that form at the North and South Poles

• the first time the temperature stays below the freezing point, causing trees to drop their leaves

• the snowy areas that form on the leeward side of mountains

• permanently frozen soil beneath the ground

According to scientists, in what climate do more than half of all plant and animal species exist

• semi-arid

• arid

• tropical wet

• tropical dry

what causes smog?

• the rain shadow effect in which clouds and pollution combine to darken skies

• the interaction of solar radiation and emissions released by burning fossil fuels

• the Coriolis effect in which swirling winds keep pollution aloft

• emissions from plant life, which produces more carbon dioxide than does human activity
