Question

____c. during the day, because the air over water is cooler and sinks, blowing toward the land.
____d. at night, because the air over water is cooler and sinks, blowing toward the land.

1. what causes a sea breeze to form?

____a. water heats up faster than land, causing air over water to rise and flow toward land.
____b. land heats up faster than water, causing air over land to rise and cooler air from the water to blow toward land.
____c. warm air from the water rises and sinks over the land, creating wind.
____d. the rotation of the earth causes wind to blow from the water to the land.

1. what happens to most of the rain that falls on earth?

____a. it goes into aquifers.
____b. it goes into oceans.
____c. it goes into the atmosphere.
____d. it goes into living things (animals & plants).

Explanation:

Question 7

A sea breeze forms due to differential heating of land and water. Land has a lower specific heat capacity than water, so it heats up faster during the day. When land heats up, the air above it warms, rises, and creates a low - pressure area. The air over water, which is cooler (since water heats up more slowly), is denser and moves towards the land (high - to - low pressure) to replace the rising warm air over land.

• Option A is incorrect because water heats up slower than land.
• Option C is incorrect as warm air from water does not rise and sink over land to create a sea breeze; it's the warm air over land that rises.
• Option D is incorrect because the Coriolis effect (due to Earth's rotation) is not the cause of sea breezes; sea breezes are due to differential heating.

Most of the rain that falls on Earth eventually makes its way to the oceans.

• Option A: Aquifers are underground layers of permeable rock or materials that hold water, but only a small portion of the rainwater infiltrates to form or recharge aquifers.
• Option C: Rain is part of the process of water returning to the atmosphere through evaporation, but most of the rain that falls does not immediately go back into the atmosphere; it flows over the land (runoff) or infiltrates and then eventually makes its way to oceans.
• Option D: While living things do take in water, the amount of rainwater that goes into living things is a very small fraction compared to the amount that goes to the oceans.

Answer:

B. Land heats up faster than water, causing air over land to rise and cooler air from the water to blow toward land.
