Warren CUSD Topic 2 Weather and Atmosphere

Lesson 1

100

An instrument that measures air pressure is called?

barometer

200

Particles of air pressing down on Earth's surface

air pressure

300

The layer of air that surrounds our planet

The atmosphere.

400

Layer of air that contains ozone and is located above the troposphere.

The stratosphere. 

500

What 3 factors cause global winds?

Global winds are caused by three main factors: uneven heating of the Earth's surface, Earth's rotation (Coriolis effect), and pressure differences. 

Lesson 2

100

The amount of moisture in the air is called?

Humidity. 

200

Name 4 types of freezing precipitation. 

Freezing rain, hail, sleet, and snow. 

300

Name 4 types of liquid precipitation.

Droplet, Mist, Drizzle, and Rain.

400

Evaporation, transpiration, and respiration are all similar becuase they involve?

The release of water into the atmosphere in the form of a vapor. 

500

Precipitation can be measured by using this tool.

A Rain Gauge. 

Lesson 3

100

The characteristics of an air mass that forms over land near Texas.

Hot and dry. 

200

The characteristics of an air mass that forms over land near Canada.

Cold and dry. 

300

The name of an air mass that forms over the ocean near Florida.

Maritime Tropical. 

400

What are two ways in which air masses move in north america?

Jet Streams, and westerlies.

500

What are the 4 types of fronts, and explain what happens in each. 

The four types of weather fronts are:

1. Cold Front: A cold air mass pushes under a warm air mass, causing the warm air to rise quickly and often leading to storms or heavy rain.
2. Warm Front: A warm air mass slowly moves over a cold air mass, bringing gradual temperature increases and steady rain or light snow.
3. Stationary Front: A boundary between a cold and warm air mass where neither is strong enough to move the other, resulting in prolonged cloudy, wet weather.
4. Occluded Front: A cold front overtakes a warm front, pushing the warm air aloft, which can lead to complex weather patterns including rain or thunderstorms.

Lesson 4

100

What is a meteorologist?

A scientist who studies and predicts the weather. 

200

List 4 pieces of weather technology. 

Weather balloons, automated weather stations, Radar, weather sattelites, computers forcasts, Weather bouys. 

300

Weather maps include information such as weather ___________ that indicate the interaction of air masses, as well as ___________ that indicate the air pressure. 

Fronts, Isobars. 

400

rapidly falling air pressure is a sign of what type of weather?

Severe weather/storms. 

500

What factors do meteorologists use to predict weather?

Air pressure, temperature, wind, humidity, and precipitation. They also track the movements of jet streams, and ocean currents to predict weather. 

Lesson 5

100

A violent disturbance in the atmosphere is called a? 

Storm. 

200

When a cyclones winds exceed 119 km/h we call it a what?

Hurricane.

300

An extremely fast spinning column of air extending from the base of a thunderstorm to the earths surface is called a?

Tornado

400

To stay safe during a tornado you should...

Go to a safe area away in the middle of the ground floor and stay away from windows and door. If a tornado hits, it is smart to have a helmet and a pair of boots to wear for after the storm. 

500

What are the requirements for lake effect snow to form?

Lake effect snow forms when three main conditions are met:

1. Cold air: Cold air moves over a warmer lake, causing the air to pick up moisture from the lake’s surface.

2. Warm lake water: The lake needs to be warmer than the air passing over it, which allows the air to absorb moisture and heat.

3. Wind direction: The wind must blow in a way that carries the moisture-filled air from the lake onto nearby land, where the air cools and the moisture falls as snow.

These conditions create heavy snowfalls, especially in areas downwind of large lakes.
