a student compares the weather on the eastern coast of the united states to the western coast. which statement best explains why the eastern coast has more rainfall and higher humidity?
a the gulf stream warms the air along the eastern coast, allowing it to hold more moisture.
b the california current moves warm air toward the eastern united states, causing storms.
c the gulf stream cools the air along the eastern coast, preventing precipitation.
d the california current decreases humidity by carrying water vapor northward.

Explanation:

The Gulf Stream is a warm ocean current. Warm air can hold more moisture than cold air. So, when the Gulf Stream warms the air along the eastern coast, that air can hold more moisture, leading to more rainfall and higher humidity.

• Option B is wrong because the California Current is a cold current and it is along the western coast, not moving warm air to the eastern US.
• Option C is incorrect as the Gulf Stream warms the air, not cools it, and warming doesn't prevent precipitation (it can lead to more as warm air holds more moisture which can condense later).
• Option D is wrong because the California Current (western coast current) is not related to the eastern - coast humidity in the way described. The California Current is cold and its main effect is on the western coast's climate.

Answer:

A. The Gulf Stream warms the air along the eastern coast, allowing it to hold more moisture.
