Question

base your answers to questions 1 and 2 on the cross section below and on your knowledge of earth science. the arrows on the cross section represent the air movement along a weather front between two different air masses. the air masses are labeled.

1. which statement best describes the difference in air temperature and humidity between the cp and mt air masses?

a) the cp air mass is warmer and less humid.
b) the mt air mass is cooler and less humid.
c) the cp air mass is cooler and more humid.
d) the mt air mass is warmer and more humid.

1. which type of front is represented by this cross section?

a) warm b) stationary c) cold d) occluded

1. what causes the coriolis effect?

a) the earths rotation
b) the equatorial calms
c) the earths revolution
d) high and low - pressure belts

1. is air rising or sinking in areas of high pressure?

a) sinking b) rising

1. what are the three main global wind belts?

Explanation:

Question 1

To solve this, we recall air mass properties: cP (continental Polar) is cool and dry (less humid), mT (maritime Tropical) is warm and moist (more humid). So we analyze each option:

• Option A: cP is not warmer, so wrong.
• Option B: mT is not cooler, so wrong.
• Option C: cP is not more humid, so wrong.
• Option D: mT is warmer and more humid (matches maritime tropical properties), so correct.

We analyze front types:

• Warm front: warm air rises over cold air (gentle slope). But the diagram shows a steeper slope? Wait, no—wait, the arrows: if it's a cold front, cold air pushes under warm air. Wait, no, the cross - section: for a cold front, the cold air (denser) advances and lifts warm air. But the options: Wait, the diagram (from the cross - section with air movement) – a cold front has a steeper slope, and cold air pushing. But wait, the options: A) warm, B) stationary, C) cold, D) occluded. Wait, the air movement: if the front is a cold front, cold air (cP) is moving into warm air (mT). But the cross - section: the arrows – if it's a cold front, the cold air is advancing. But wait, the other way: wait, the correct front type here – let's recall: a cold front is when cold air mass moves into a warmer air mass, forcing warm air to rise rapidly. But the diagram (from the image description) – maybe it's a cold front? Wait, no, wait the options. Wait, the correct answer for front type: Let's think again. The air masses: cP (cold, dry) and mT (warm, moist). The front where cold air is pushing into warm air is a cold front? Wait, no, wait the cross - section: if the arrows show the cold air (cP) moving towards the mT, and the warm air is being lifted. But the options: Wait, maybe the front is a cold front? Wait, no, the correct answer is C? Wait, no, wait the diagram: maybe it's a cold front. Wait, let's check the front types:
• Warm front: warm air moves over cold air (gentle slope, long - duration precipitation).
• Cold front: cold air moves under warm air (steeper slope, intense precipitation).
• Stationary: neither moves significantly.
• Occluded: cold front catches up to warm front.

From the air movement (arrows) – if the cold air (cP) is moving towards the mT, and the warm air is rising, it's a cold front. So the correct option is C? Wait, no, wait the original problem's cross - section: maybe it's a cold front. So the answer is C.

The Coriolis effect is caused by the Earth's rotation. We analyze the options:

• Option A: Earth's rotation causes Coriolis (correct, as it deflects moving objects like air/water).
• Option B: Equatorial calms are a wind pattern, not the cause of Coriolis.
• Option C: Earth's revolution (around Sun) does not cause Coriolis.
• Option D: High/low - pressure belts are a result of air movement, not the cause of Coriolis.

So the correct option is A.

Answer:

D. The mT air mass is warmer and more humid.
