What is radiation in the context of weather?

• The process responsible for the uneven heating of air in the atmosphere.

• A type of precipitation that occurs during storms.

• The movement of air masses across different regions.

• The reflection of sunlight off the Earth's surface.

What is a warm front?

• A boundary where a warm air mass slides over a cold air mass, usually bringing gentle rain.

• A boundary where a cold air mass slides under a warm air mass, often causing thunderstorms.

• A region where two air masses meet but do not move, leading to stable weather conditions.

• A transition zone where warm air rises rapidly, resulting in severe weather.

Why do winds at the beach change direction between day and night?

• Because the temperatures over land and over water change.

• Because of the rotation of the Earth.

• Due to the presence of sand dunes.

• Because of ocean currents.

What role does the Gulf Stream play in weather?

• It cools the air above it, leading to colder weather patterns.

• It warms the air above it, affecting weather patterns along the eastern U.S. coast.

• It has no significant impact on weather patterns.

• It creates storms and hurricanes in the Gulf of Mexico.

What are air masses?

• Large bodies of air that have uniform temperature and humidity characteristics.

• Small pockets of air that vary in temperature and humidity.

• Air layers that are always moving and changing.

• Cloud formations that indicate weather patterns.

How do prevailing westerlies affect air mass movement in the U.S.?

• They move air masses from east to west across the United States.

• They have no effect on air mass movement in the United States.

• They move air masses from west to east across the United States but may be deflected by the jet stream.

• They only affect air mass movement in the southern United States.

What is humidity?

• The amount of water vapor present in the air.

• The measure of how hot or cold the air is.

• The amount of oxygen in the atmosphere.

• The pressure exerted by the air in the environment.

What is transpiration?

• The process by which green plants control the amount of water stored in their leaves.

• The process of photosynthesis in plants.

• The absorption of water by plant roots.

• The release of oxygen by plants during the day.

What is a low pressure weather system likely to cause?

• Sunny conditions.

• Cloudy conditions.

• Clear skies.

• Strong winds.

What is conduction?

• The transfer of heat through direct contact between materials.

• The process of heat transfer through fluids by the movement of the fluid itself.

• The transfer of heat through electromagnetic waves.

• The process of heat transfer through the movement of electrons in a conductor.
