a measurement of the hotness of coldness of something using a thermometer

Question 9

Local variations of heat gain and loss are also affected by

Answer 9

bodies of water and land features

Question 10

Define Humidity

Answer 10

the amount of water in a given volume of air, affects evaporation

Question 11

extended periods of low humidity can cause

Answer 11

droughts & a factor leading to wildfires

Question 12

What do Meteorologist measure, ___ of air in order to understand weather conditions

Answer 12

relative humidity

Question 13

what is relative humidity?

Answer 13

the amount of water in the air as a percentage of the maximum amount of water that the air can hold at a given temperature

Question 14

When air cannot hold anymore water vapor, we call it?

Answer 14

Saturated

Question 15

Evaporations from our bodies occurs more readily in____ with lower relative humidity that it does in humid heat of the same temperature, leaving us feeling cooler and more comfortable

Answer 15

dry heat

Question 16

Define Barometric pressure

Answer 16

a measure of the pressure exerted by Earth’s atmosphere at any given point is rising (indicating increasing air pressure) or falling (indicating decreasing air pressure)

Question 17

A barometer is

Answer 17

an instrument that detects the weight of the air in the atmosphere as it presses against a confined substance, such as mercury & moderns day its electronic devices, that measure the electrical resistance of atmospheric pressure

Question 18

What is air mass?

Answer 18

a large volume of air typically several kilos thick and a thousand or more kilos wide

Question 19

High-pressure-system

Answer 19

associated with clear and dry conditions. They contain cooling air that is becoming denser and heavier which sinks to form areas of high pressure, big H’s on weather maps

Question 20

What does the Sahara, Kalahari and Gobi Deserts exist?

Answer 20

Because of semipermanent high pressure conditions

Question 21

Low Pressure System

Answer 21

system of air where warm, rising air cools as it expands into higher and colder altitudes. The cooling can cause the water vapor in the air mass to condense into clouds that may cause rain

Question 22

The more moisture in the air or are the heavier

Answer 22

the rains or snow

Question 23

Wind is

Answer 23

air in motion as it flows from high pressure to low pressure areas

Question 24

Cold Front

Answer 24

cold air mass replacing a warm air mass

Question 25

Wind

Answer 25

air in motion as it flows from high pressure to low pressure areas

Question 26

Cold Front

Answer 26

a cold air mass replacing a warm air mass

Question 27

Warm Front

Answer 27

a warm air mass replacing a cold air mass
