weather test for 7th grade science

Describe cirrus, stratus, and cumulus clouds.

• cirrus: low wispy clouds with snow. stratus: high flat clouds. cumulus. wispy clouds that are in the middle.

• CIRRUS: high wispy clouds with ice crystals. STRATUS: Low flat clouds. CUMULUS: Fluffy cotton ball looking clouds.

• I can't define them but I can list the weather

• I need more help with this concept

What does it mean if the cloud name has alto in it? What about nimbus?

• alto: low

  nimbus high

• alto: high

  nimbus: low

• ALTO: Middle

  NIMBUS: cloud that produces precipitation

• Nimbus: middle

  alto: low

Define air mass and front.

• I have no clue

• I want to skip this question because I already know i, maybe

• air mass: a small volume of air in the atmosphere that is mostly uniform in weight and moisture.

  front: a boundary between two wet and moist air masses.

• AIR MASS: a large volume of air in the atmosphere that is mostly uniform in temperature and moisture.

  FRONT: A boundary between air masses.

Define the following air masses and explain the type of weather they bring. Continental, maritime, polar, tropical

• Continental: Forms over land (dry air mass)

  Maritime: Forms over water (humid air mass with a lot of water vapor in it)

  Polar: Cold air mass

  Tropical: Warm air mass

• no clue

• polar: forms over water (wet air mass)

  maritime: forms over ice ( dense )

  tropical: warm and humid

  continental: forms over land ( dry air mass)

Define the following air masses, and describe the weather they create.

• cold front: cold air mass

  warm front: warm air mass

  stationary front: brings hot air

  occluded front brings lots of rain and thunder storms.

• Cold front- Cold air mass quickly collides with warm air mass and causes thunderstorms, warm front- Warm air mass slowly slides over top of cold air mass and causes days of rain and clouds, occluded front- Cold front collides with a warm front which causes rain and thunderstorms,

  stationary front- warm air mass and cold air mass sit next to each other without moving which causes clear skies or light rain and clouds

Define air pressure? What instrument measures air pressure?

• air pressure - the force of air pushing on an object

  measured by a anemometer

• no clue

• Air pressure- the force of air pushing on an object. Measured by a barometer

• air pressure- the force of wind pushing down on an object

  measured by a hygrometer

Define a high pressure system and low pressure system. What type of weather do high pressure systems and low pressure systems bring?

• I need help

• high pressure system- is high pressure

  low pressure system - is low pressure

• no clue

• High pressure system- an area of cold, higher pressure air than the air around it. The cold air sinks and spreads as it warms which suppresses the formation of weather Low pressure system- an area of warm, lower pressure air than the air around it. The warm air rises and condenses as it cools which forms clouds and leads to precipitation.

Define tornado, blizzard, hurricane, and thunderstorm.

• Tornado- A violent rotating column of air extending from a thunderstorm to the ground.

  Blizzard- A long lasting snow storm with very strong winds and intense snowfall.

  Hurricane- A huge storm with violent winds and heavy rain that forms over the ocean and gathers its heat and energy from the ocean waters.

  Thunderstorms-A storm with lightning and thunder that is produced by cumulonimbus clouds. It has strong gusts of wind, heavy rain and sometimes hail.

• no clue

• need help

• Blizzard- lots of snow

  tornado- funnel cloud with wind

  hurricane - lost of wind over the warm ocean

  thunderstorms- thunder and lightning

What conditions need to happen for each type of severe weather to occur? (pressure system, front, winds, etc)

• Tornado-Warm moist air mass, cold dry air mass, change in wind speed (increase) wind direction, and udrat spinning motion.

  Blizzard-Cold air at the surface, lift and moisture.

  Hurricane- low air pressure,warm temperature,moist ocean air and tropical winds.

  Thunderstorms- Moisture, lift and unstable air.

• no clue

• need help

• Tornado-Warm moist air mass

  Blizzard-Cold air at the surface

  Hurricane- low air pressure

  Thunderstorms- Moisture,
