Flashcards
Q: What causes the movement of air in the atmosphere?
A: Differences in air pressure caused by uneven heating of the Earth’s surface.
A: Differences in air pressure caused by uneven heating of the Earth’s surface.
Q: What is the Coriolis effect?
A: It is the deflection of moving objects, including wind, due to Earth’s rotation.
A: It is the deflection of moving objects, including wind, due to Earth’s rotation.
Q: What is the difference between tropical and temperate cyclones?
A: Tropical cyclones form over warm oceans, while temperate cyclones form in mid-latitudes due to the meeting of air masses.
