Science (Weather)

Front 1

What causes a flood?

Back 1

Floods occur when so much water pours into a stream or river that it overflows its banks and covers the land on either side of the channel.

Front 2

Meteorologists

Back 2

scientists who study the causes of weather and try to predict it

Front 3

Tornado

Back 3

A rapidly whirling, funnel shaped cloud that reaches down from the storm cloud to touch Earth's surface.

Front 4

Isobar

Back 4

lines joining places on the map that have the ame air pressure

Front 5

Cold Front

Back 5

When a rapidly moving cold air mass runs into a slowly moving warm air mass, the denser cold air slides under the lighter warm air.

Front 6

Isotherm

Back 6

Lines joining places that have the same temperature.

Front 7

Occluded Front

Back 7

A warm air mass is caught between two cooler air masses. The denser cool air masses move underneath the less dense warm air mass and push it upward. The two cooler air masses meet in the middle and may mix.

Front 8

Cyclone

Back 8

A swirling center of low air pressure.

Front 9

Hurricane

Back 9

A tropical storm that has winds of 119 kilometers per hour or higher.

Front 10

Warm Front

Back 10

A moving warm air mass collides with a slowly moving cold air mass. Because cold air is more dense than warm air, the warm air moves over the cold air.

Front 11

Anticyclone

Back 11

High pressure centers of dry air.

Front 12

Storm

Back 12

A violent disturbance in the atmosphere.

Front 13

In what kind of clouds do thunderstorms form?

Back 13

Large cumulonimbus clouds (thunderheads).

Front 14

Stationary Front

Back 14

When cold and warm air masses meet and neither has enough force to move the other.

Front 15

Lightning

Back 15

A sudden spark, or energy discharge, as electrical charges jump from cloud to cloud or cloud to ground.
