Question

explain how air pressure changes as you travel away from earths surface. use information from the passage to support your answer. you travel further from the surface of the earth through the atmosphere. air moving from areas of high pressure to low pressure at earths surface. your ears pop while traveling in an airplane. gas molecules in the atmosphere spread out becoming less dense.

Explanation:

Air pressure is determined by the weight of the air column above. As you move further from Earth's surface through the atmosphere, there is less air above, so air pressure decreases. Gas molecules in the atmosphere spread out as pressure drops, becoming less dense. In an airplane, the change in external air - pressure can cause a pressure difference between the inside of the ear and the outside environment, leading to ears "popping" as the body tries to equalize the pressure.

Answer:

As you travel further from the Earth's surface through the atmosphere, air pressure decreases because there is less air above exerting weight. This causes gas molecules in the atmosphere to spread out and become less dense. In an airplane, the change in air pressure can lead to your ears "popping" as the body attempts to equalize the pressure between the inner ear and the external environment.
