1 multiple choice 1 point
what creates local winds like land and sea breezes?
temperature differences between land and water
differences in pressure over large areas
the coriolis effect
ocean currents
2 multiple choice 1 point
what are jet streams?
winds that blow at sea level
narrow, fast - flowing air currents in the upper atmosphere

Explanation:

Question 1

To determine the cause of local winds like land and sea breezes, we analyze each option:

• "Temperature differences between land and water": Land and water have different heat capacities. During the day, land heats up faster than water, creating a low - pressure area over land and a high - pressure area over water, causing sea breeze. At night, the reverse happens, causing land breeze. So this is correct.
• "Differences in pressure over large areas": This is related to global wind patterns or large - scale pressure systems, not local land - sea breezes.
• "The Coriolis effect": It affects the direction of winds over large distances, not the formation of local land - sea breezes.
• "Ocean currents": Ocean currents are related to the movement of ocean water, not the formation of local winds.

To identify what jet streams are:

• "Winds that blow at sea level": Jet streams are not at sea level; they are in the upper atmosphere. So this is incorrect.
• "Narrow, fast - flowing air currents in the upper atmosphere": This is the correct definition of jet streams. They are high - altitude, fast - moving air currents that play a role in weather patterns.

Answer:

A. Temperature differences between land and water

Question 2

(Assuming the second option for jet streams is "Narrow, fast - flowing air currents in the upper atmosphere" and the first is incorrect as jet streams are in the upper atmosphere, not at sea level)
