The sky is falling! (weather/atmosphere)

How is air pressure different at the top and bottom of a mountain?

• Air pressure is higher at the top

• Air pressure is less at the top

• Air pressure is equal at the top and bottom

• Air pressure does not depend on altitude but on time of day factors.

Why is the mesosphere colder than the troposphere?

• mesosphere is closer to the ground

• mesosphere contains ozone

• mesosphere's molecules are further spaced apart

• troposphere's molecules are further spread apart

Which system results in rainy or stormy weather?

• high pressure
• low pressure
• hurricane
• weather system

What type of storm front is this?

• warm front
• cold front
• stationary front
• occluded front

Where would you find a tropical maritime air mass?

• over the ocean, near the equator
• over the ocean, near the poles
• over a continent, near the equator
• over a continent, near the poles

A wet, cold air mass would be - 

• maritime tropical 
• maritime polar
• continental tropical 
• continental polar

Rain and melted snow that do not evaporate or soak into the soil flow into streams and rivers. What is this part of the water cycle called?

• Watershed
• Surface runoff
• Aquifers
• Standing water

What provides the energy that drives the water cycle?

• Sun
• Moon
• Precipitation
• Glaciers

What role do ocean currents play in weather and climate?

• They influence the temperature and precipitation levels of various regions with their flow patterns.
• They reflect aerosols from the ocean surface back into the atmosphere.
• They counteract human influence on climate by helping to circulate deeper, colder waters.
• They promote evaporation and therefore more efficiently distribute the sun�s heat.

What causes wind to blow?

• Differences in longitude 
• Shock waves from clouds 
• Differences in air temperature and pressure 
• The rotation of the earth
