Geography Chapter 2

Desert and tundra regions are alike in which of the following ways?

• In both regions, plants and animals have to be able to survive without water.

• Both areas are subject to unexpected weather changes

• In both regions, only plants that can adjust to extreme temperatures can survive

• The few animals that are native to each region live very short lives

Some scientists theorize that global warming

• is caused by melting glaciers

• is the result of increased levels of carbon dioxide in the atomosphere

• will eventually result in colder temperatures at the North and South poles

• will result in a sharp drop in ocean levels.

Which of the following is NOT affected by the relative positions of the sun and the earth?

• climate

• seasons

• thunderstorms

• day and night

Which of the following statements about convection is incorrect?

• Movements of air are called wind; movements of water are called currents

• Cold air and cold water flow from the Equator toward the poles

• It occurs because warm gases and liquids are lighter than cool gases and liquids

• Cooler, heavier gases sink and displace lighter materials

Climate regions are classified mainly on the basis of

• distance from the Equator

• elevation

• seasonal temperatures and precipitation

• rainfall and location

The central regions of several continents are covered by

• forests

• deserts

• grasslands

• tundra

All of the following are accurate statements about weather and climate except

• Ocean waters help to distribute the sun's heat

• Precipitation depends on air temperature and winds

• Coastal areas usually have milder climates than do areas at the same latitude inland

• Most areas with continental climates have a mild, humid climate all year long

All of the following are accurate statements about ecosystems except

• The plants in an ecosystem depend upon one another for shade, support, and food

• The same types of plants grow in similar environments around the world

• The plants and animals in a biome frequently are not suited to one another

• Climate, sunlight, temperature, precipitation, elevation, soil, and landforms affect life in an ecosystem

Broadleaf deciduous forests grow best in regions with a

• temperate climate and adequate rainfall

• Mediterranean climate

• tropical climate and heavy seasonal rainfall

• cool and dry climate

Climate depends on such factors as an area's

• elevation and longitude

• latitude and solstice

• elevation and latitude

• elevation and equinox
