Tropical

Answer 2

places found on or close to the Equator are typically tropical: they’re warm and wet

Question 3

Celsius

Answer 3

a scale for measuring temperature, in which water freezes at 0 degrees and boils at 100 degrees

Question 4

Cumulous cloud

Answer 4

puffy clouds that look like puffs of cotton

Question 5

Cirrus cloud

Answer 5

short, detached, hair-like clouds found at high altitudes

Question 6

Thermometer

Answer 6

a device that measures temperature

Question 7

Tropical depression

Answer 7

a tropical cyclone that has maximum sustained surface winds (one-minute average) of 38 mph (33 knots) or less

Question 8

Ocean current

Answer 8

the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density

Question 9

Dew point

Answer 9

the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%

Question 10

Hurricane

Answer 10

a tropical storm with winds that have reached a constant speed of 74 miles per hour or more

Question 11

Desert

Answer 11

arid land with usually sparse vegetation especially

Typhoon

Answer 12

a tropical cyclone with winds faster than 74 miles per hour

Question 13

Humidity

Answer 13

the amount of water vapor in the air

Question 14

Forecast

Answer 14

a technique that uses historical data as inputs to make informed estimates that are predictive in determining the direction of future trends

Question 15

Atmosphere

Answer 15

the whole mass of air that surrounds the earth.

Question 16

Hail

Answer 16

pellets of frozen rain which fall in showers from cumulonimbus clouds.

Question 17

Thunderstorm

Answer 17

storm caused by strong rising air currents and characterized by thunder and lightning and usually heavy rain or hail

Question 18

Cloud

Answer 18

a visible mass of particles of condensed vapor (such as water or ice) suspended in the atmosphere of a planet

Question 19

Precipitation

Answer 19

water released from clouds in the form of rain, freezing rain, sleet, snow, or hail

Question 20

Drought

Answer 20

prolonged period of abnormally low rainfall, leading to a shortage of water

Question 21

Front

Answer 21

a transition zone between two different air masses at the Earth’s surface

Question 22

Meteorology

Answer 22

the branch of science concerned with the processes and phenomena of the atmosphere, especially as a means of forecasting the weather

Answer 23

the temperature at which a liquid turns into a solid when cooled.

Question 24

Tornado

Answer 24

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

Question 25

Cumulonimbus cloud

Answer 25

menacing looking multi-level clouds, extending high into the sky in towers or plumes

Question 26

Thunder

Answer 26

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

Question 27

Answer 27

the state of the atmosphere with respect to heat or cold, wetness or dryness, calm or storm, clearness or cloudiness

Question 28

Waterspout

Answer 28

whirling column of air and water mist

Question 29
