Chapter 6 Study Guide

Question 1

weather

Answer 1

the condition of the atmosphere as it is affected by temperature

Question 2

air mass

Answer 2

a large body of air with consistent temperature and moisture content throughout

Question 3

wind

Answer 3

the horizontal movement of air that occurs as a result of pressure differences between two air masses

Question 4

thermals

Answer 4

a small, upward flow of warm air

Question 5

coriolis effect

Answer 5

the bending of currents of air or water due to Earth’s rotation; northern hemisphere wind turns right, southern hemisphere wind turns left

Question 6

jsyk - pressure

Answer 6

low pressure areas cause rising warm air that typically causes rainy or snowy weather

high pressure areas are caused by sinking cold air, high pressure usually causes clear weather

Question 7

relative humidity

Answer 7

a measure of how much water vapor an air mass can hold

Question 8

jsyk - evaperation

Answer 8

increasing air temperature increases evaperation

Question 9

cumulus clouds

Answer 9

clouds that are tall and puffy and form when the air over land is heated, below 2,000 meters

Question 10

cirrus clouds

Answer 10

thin lines of ice above 6,000 meters in the sky

Question 11

stratus clouds

Answer 11

looks like fog that didn’t reach the ground, below 2,000 meters

Question 12

cumulonimbus clouds

Answer 12

dark and stormy cumulus cloud, between 2,000 and 15,000 meters high

Question 13

tornado

Answer 13

a system of rotating wind around a low pressure center; faster and smaller than a hurricane

Question 14

hurricane

Answer 14

a tropical cyclone with wind speeds of at least 74 mph

Question 15

jsyk - hurricanes and tornados

Answer 15

hurricanes and tornados have low pressure centers

Question 16

isobars

Answer 16

a line on a weather map that connects places that have the same atmospheric pressure

Question 17

climate

Answer 17

the general weather over a long period

Question 18

cold front

Answer 18

when a cold air mass moves in and replaces the front

Question 19

warm front

Answer 19

when a warm air mass moves and replaces a cold air mass

Question 20

dew point

Answer 20

the temperature at which more water condenses than evaporates in an air mass

Question 21

Answer 21

a major climate region with particular plans and animals; 6 major biomes: deserts, grasslands, temperate deciduous forests, rain forests, taigas, and tundras

Question 22

a temperate deciduous forest has what?
