Question 1

Humidity

Answer 1

Amount of water vapor in the air.

Question 2

Cumulus Cloud

Answer 2

Puffy, white clouds with flat bottoms.

Question 3

Stratus Cloud

Answer 3

Clouds that form in layers that cover large areas of the sky and can block out the sun.

Question 4

Cirrus Cloud

Answer 4

Thin, Feathery white clouds found at high altitudes. Form when the wind is strong.

Question 5

Cumulonimbus Cloud

Answer 5

Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents.

Question 6

Condensation

Answer 6

The change of state from a gas to a a liquid

Question 7

Evaporation

Answer 7

the process of turning from liquid into vapor.

Question 8

Precipitation

Answer 8

Any form of water that falls to the earths surface from the clouds.

Question 9

Runoff

Answer 9

the draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.

Question 10

Rain

Answer 10

moisture condensed from the atmosphere that falls visibly in separate drops.

Question 11

Sleet

Answer 11

a form of precipitation consisting of ice pellets, often mixed with rain or snow.

Question 12

Snow

Answer 12

atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer.

Question 13

Hail

Answer 13

pellets of frozen rain which fall in showers from cumulonimbus clouds.
“rain and hail bounced on the tiled roof”

Question 14

Polar – Maritime Air mass

Answer 14

Polar maritime is the most common air mass to affect the British Isles. This air mass starts very cold and dry but during its long passage over the relatively warm waters of the North Atlantic its temperature rises rapidly and it becomes unstable to a great depth.

Question 15

Tropical – Maritime Air Mass

Answer 15

Tropical maritime air is warm and moist in its lowest layers and, although unstable over its source region, during its passage over cooler waters becomes stable and the air becomes saturated.

Question 16

Polar – Continental Air Mass

Answer 16

This air mass has its origins over the snow fields of Eastern Europe and Russia and is only considered a winter (November to April) phenomena. During the summer with the land mass considerably warmer, this air mass would be classed as a tropical continental.

Question 17

Tropical – Continental Air mass

Answer 17

Continental Tropical air masses (cT) are a type of tropical air produced by the subtropical ridge over large areas of land and typically originate from low-latitude deserts such as the Sahara Desert in northern Africa, which is the major source of these air masses.

Question 18

Cold Front

Answer 18

cold front is the leading edge of a cooler mass of air at ground level that replaces a warmer mass of air and lies within a pronounced surface trough of low pressure

Question 19

Warm Front

Answer 19

A warm front is the boundary between a mass of warm air and a retreating mass of cold air. At constant atmospheric pressure, warm air is less dense than cold air, and so it tends to override, rather than displace, the cold air.

Question 20

Thunderstorm

Answer 20

a storm with thunder and lightning and typically also heavy rain or hail.

Question 21

Lightning

Answer 21

the occurrence of a natural electrical discharge of very short duration and high voltage between a cloud and the ground or within a cloud, accompanied by a bright flash and typically also thunder.

Question 22

Thunder

Answer 22

a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.

Question 23

Tornado

Answer 23

a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.

Question 24

Hurricane

Answer 24

a storm with a violent wind, in particular a tropical cyclone in the Caribbean.

Question 25

Thermometer

Answer 25

an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling.

Question 26

Anemometer

Answer 26

an instrument for measuring the speed of the wind, or of any current of gas.
