Front

What happens when a warm air mass passes over a cold air mass?

Back

Clouds will begin to form, and rain will fall.

Front

How does the jet stream affect the weather in cities north and south of it?

Back

The city at Arrow A (north of the jet stream) will experience cooler air, higher surface pressure, and more humid air.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns of temperature and precipitation in an area.

Front

What is an example of climate?

Winters in Ft. Lauderdale have been consistently dry over the past 50 years.

Front

What drives convection currents in the Earth's mantle?

Back

Heat from the Earth’s core drives convection currents in the mantle.

Front

What is sea-floor spreading?

Back

Sea-floor spreading is the process where tectonic plates move apart due to convection currents, allowing magma to rise and create new oceanic crust.

Front

What is the role of the Earth's core in geological processes?

Back

The Earth's core provides heat that drives convection currents in the mantle, influencing tectonic activity.

Front

What is a jet stream?

Back

A jet stream is a fast-flowing air current in the atmosphere that influences weather patterns.

Front

What is the significance of ocean basins?

Back

Ocean basins are large depressions in the Earth's surface that hold ocean water, formed by tectonic processes.

Front

What is the definition of humidity?

Back

Humidity is the amount of water vapor present in the air.
