Test: Weather & Water in Earth's Atmosphere

How does the air move in a sea breeze?

• wind moves from north to south
• wind moves from ocean to the land
• wind moves from the land to the ocean
• wind moves from south to north

The strength of a sea breeze depends on

• the heat of the day
• the difference between the temperature of the sea and the land
• the wind speed
• the amount of precipitation that day

The equator is warmer because it receives 

• Indirect sunlight in the form of Ultra-Violet Radiation. The sun is able to focus most of its energy directly at the polar regions
• Direct sunlight in the form of Ultra-Violet Radiation. The sun is able to focus most of its energy directly at the equator than at the polar regions.

Winds are caused by 

• equal heating of the Earth's atmosphere. This is due to the indirect sunlight penetrating the atmosphere in the tropics, and direct sunlight penetrating the atmosphere in the polar regions.
• unequal heating of the Earth's atmosphere. This is due to the direct sunlight penetrating the atmosphere in the tropics, and indirect sunlight penetrating the atmosphere in the polar regions.

Air moves from an area of _______ Pressure to ________ Pressure

• High to Low
• Low to High

What are the names of the winds that move systems in the continental United States?

• Prevailing Westerlies
• Polar Easterlies
• Trade Winds
• Land Breezes

What role does air pressure play in weather systems?

• Its force determines the strength of the wind
• It creates downdrafts that blow from the shore
• It is the primary cause of trade winds
• It determines how high or low the tide is.

Which three weather elements affect pressure?

• wind, earth's distance from the moon, and clouds
• amount of plant life, wind, and level of water in the ocean
• height above sea level, temperature, and amount of water vapor
• temperature, wind, and how much animal or plant life is around

What is a convection cell?

• an extremely dense and heavy mass of air
• a place on the beach where scientists watch weather
• an instrument scientists use to measure wind speed
• a pattern of rising warm air and sinking cool air
