Study guide on the movement of air, featuring diagrams of air circulation and wind patterns.

Let’s go step by step to answer each question based on the diagrams and what we know about air movement.

Questions 1–8: Fill in the blanks using terms from the word bank (not shown, but we can infer common terms for this topic).

Since the word bank isn’t visible, I’ll use standard science terms that fit these questions about air movement, pressure, wind, and Earth’s rotation.

1. Air moves from areas of high pressure to areas of low pressure.
→ So blank = *high* or *low*? Let’s think: Air flows FROM high TO low. So if it says “moves from ___ to ___”, first is high, second is low. But since only one blank per line, likely asking for direction or cause. Wait — looking at typical worksheets, Q1 might be: “Wind is caused by differences in ______.” → Answer: *air pressure*

But without the exact wording, let’s assume common fill-ins:

Actually, looking at the diagram labels and context:

Diagram A shows convection current over land/sea → sea breeze/daytime
Diagram B shows land breeze/nighttime
Top circle shows global wind patterns with latitudes

Common answers for such worksheets:

1. Wind is caused by differences in air pressure.
2. Air rises when it is heated.
3. Air sinks when it is cooled.
4. The Coriolis effect causes winds to curve due to Earth’s rotation.
5. Near the equator, warm air rises creating a zone of low pressure.
6. At about 30° latitude, cool air sinks creating a zone of high pressure.
7. Winds blowing from west to east are called westerlies.
8. Winds blowing from east to west near the poles are called polar easterlies.

*(Note: These are educated guesses based on standard curriculum. If you have the actual word bank, match those words.)*

Question 9: In the blank on Fig. A, write the time best suited to conditions.

Fig. A shows air rising over land, sinking over water, surface wind from sea to land → This is a sea breeze, which happens during the day (when land heats up faster than water).

→ Answer: Daytime

---

Question 10: In the blank on Fig. B, write the time best suited to conditions.

Fig. B shows air rising over water, sinking over land, surface wind from land to sea → This is a land breeze, which happens at night (when land cools faster than water).

→ Answer: Nighttime

Question 11: Using all six names from their original paths (shown at Earth’s Surface), draw arrows to show how the air masses would move with world wind flow patterns.

This refers to the top circular diagram showing global wind belts:

- Near equator: Trade Winds (blow east to west)
- Around 30°: Westerlies (blow west to east)
- Near poles: Polar Easterlies (blow east to west)

You’re supposed to draw arrows on the map following those directions.

Since we can’t draw here, describe:

→ From equator toward 30°N/S: Arrows pointing westward (Trade Winds)
→ From 30° toward 60°: Arrows pointing eastward (Westerlies)
→ From poles toward 60°: Arrows pointing westward (Polar Easterlies)

Also, remember the Coriolis effect curves them right in Northern Hemisphere, left in Southern.

Question 12: What atmospheric pressure at Earth’s surface is shown in Figure A?

In Figure A (sea breeze):
- Land is warmer → air rises → creates low pressure at surface over land
- Water is cooler → air sinks → creates high pressure at surface over water

So surface pressure over land = Low
Surface pressure over water = High

The question probably asks for the pressure type over land (since that’s where air is rising).

→ Answer: Low pressure

Question 13: Consider movements at rest that cause the winds shown in Figure 2.

Wait — there’s no Figure 2 labeled. Probably typo — they mean Figure B?

Assuming Figure B (land breeze):

At night, land cools faster → air over land becomes denser and sinks → creates high pressure over land
Water stays warmer → air rises over water → low pressure over water
Wind blows from land (high) to water (low)

So the movement at rest (before wind starts) is:
→ Cooling of land air → sinking → high pressure
→ Warming of water air → rising → low pressure
→ Then wind flows from high to low

Answer: Cooling of land causes air to sink and create high pressure; warming of water causes air to rise and create low pressure, resulting in wind from land to sea.

Now, compiling final answers clearly:

──────────────────────────────────────

Final Answer:
1. air pressure
2. heated
3. cooled
4. rotation
5. low pressure
6. high pressure
7. westerlies
8. polar easterlies
9. Daytime
10. Nighttime
11. [Draw arrows: Trade Winds westward near equator, Westerlies eastward at mid-latitudes, Polar Easterlies westward near poles — curved by Coriolis]
12. Low pressure (over land in Fig. A)
13. At night, land cools faster than water, causing air over land to sink (high pressure) and air over water to rise (low pressure), so wind blows from land to sea.
