Atmospheric pressure is a measure of which of the following?
Correct Answer
B. The weight of air pushing down on Earth
Explanation
Atmospheric pressure is a measure of the weight of air pushing down on Earth. As air molecules have mass, they exert a force on the Earth's surface due to gravity. The weight of the air above a particular point on Earth creates atmospheric pressure, which can be measured using various instruments such as barometers. This pressure is responsible for various weather phenomena and affects the behavior of gases, liquids, and solids on the Earth's surface.

Which of these best explains why cities on opposite sides of a mountain receive different amounts of rain?
Correct Answer
D. The orograpHic effect
Explanation
The orographic effect best explains why cities on opposite sides of a mountain receive different amounts of rain. This effect occurs when moist air is forced to rise over a mountain, causing it to cool and condense, leading to increased precipitation on the windward side. As the air descends on the leeward side, it warms and dries out, resulting in less rainfall. This phenomenon is responsible for the stark contrast in rainfall patterns between the two sides of a mountain.
