The mixture of nitrogen, oxygen, and other gases that surround the earth

Question 10

Cold front

Answer 10

A fast moving cold air mass collides with a warm air mass pushing the mass air up, forming clouds, storms, and thunderstorms

Question 11

Stationary front

Answer 11

Where a warm air mass and a cold air mass meet and neither have the energy to move the other out, clouds often form and may bring precipitation for many days

Question 12

Precipitation

Answer 12

Water, in a solid or liquid form, that falls from the air to the earth, such as rain, snow, sleet, or hail

Question 13

A tool that measures wind speed

Question 15

Sling psychrometer

Answer 15

A tool that measures relative humidity

Question 16

Troposphere

Answer 16

The layer of earths atmosphere in which we live. As u move up through this layer of the atmosphere, wind speed increases, but temp and air pressure decrease

Question 17

Condensation

Answer 17

The process by which gas becomes a liquid such as fog,dew, and clouds

Question 18

Storm surge

Answer 18

A local rise in sea level near the shore that is caused by strong winds from a storm, such as a hurricane. It is the most destructive part of a hurricane

Question 19

Flash flooding

Answer 19

Question 27

Weather forecasting

Answer 27

The analysis of scientific data to predict future weather conditions

Question 28

Weather front

Answer 28

A boundary separating 2 masses of air of different densities, these air masses collide and don’t mix

Question 29

Warm front

Answer 29

A slow moving warm air mass moves over a slow moving cold air mass the warm air moves over the cold air mass, this causes clouds to form bringing drizzly rain showers and fog

Question 30

Occluded front

Answer 30

A warm air mass is trapped between two cold air masses, the cold air forces the warm air up creating clouds, this can lead to cold temperatures rain and snow
