weather

Question 1

Humidity

Answer 1

.the state or quality of being humid.

a quantity representing the amount of water vapor in the atmosphere or a gas.

Question 2

Cumulus Cloud

Answer 2

.Cumulus clouds are clouds which have flat bases and are often described as “puffy”, “cotton-like” or “fluffy” in appearance. Their name derives from the Latin cumulo-, meaning heap or pile.

Question 3

Stratus Cloud

Answer 3

.Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals

Question 4

Cirrus Cloud

Answer 4

.Cirrus is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair.

Question 5

Cumulonimbus Cloud

Answer 5

,Cumulonimbus, from the Latin cumulus and nimbus, is a dense, towering vertical cloud associated with thunderstorms and atmospheric instability, forming from water vapor carried by powerful upward air currents.

Question 6

Condensation

Answer 6

‘the conversion of a vapor or gas to a liquid.

Question 7

Evaporation

Answer 7

.the process of turning from liquid into vapor.

Question 8

Precipitation

Answer 8

.the action or process of precipitating a substance from a solution.
2.
rain, snow, sleet, or hail that falls to the ground.

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 that fall in showers from cumulonimbus clouds

Question 14

Polar – Maritime Airmass

Answer 14

.Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.

Question 15

Tropical – Maritime Airmass

Answer 15

.originate over the warm waters of the tropics and Gulf of Mexico, where heat and moisture are transferred to the overlying air from the waters below. The northward movement of tropical air masses transports warm moist air into the United States, increasing the potential for precipitation.

Question 16

Polar – Continental Airmass

Answer 16

.Continental Polar Air Masses cold temperatures and little moisture. Those who live in northern portions of the United States expect cold weather during the winter months. These conditions usually result from the invasion of cold arctic air masses that originate from the snow covered regions of northern Canada.

Question 17

Tropical – Continental Airmass

Answer 17

.is a dry air mass formed over land in area close to the equator. An example of a tropical continental is a mass of warm air that forms over northern Mexico.

Question 18

Cold Front

Answer 18

.the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.

Question 19

Warm Front

Answer 19

.the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system.

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.
a wind of force 12 on the Beaufort scale (equal to or exceeding 64 knots or 74 mph)

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
