<h3>
Answer: Choice (4) in the bottom right corner</h3>
===========================================================
Explanation:
The sun warms up the land and the air adjacent to the land. The earth/rocks aren't a very good heatsink compared to the water, so effectively the heat energy bounces off the land and into the air. The land-adjacent air is heated much quicker compared to the water-adjacent air. The warm air over the land rises because the air particles are more energetic to bounce around faster. The rising warm air spreads out not only vertically but also horizontally as the diagram shows.
As the warm air moves over the colder lake, the warm air cools down and sinks. The breeze from the lake moves toward the land, due to the pressure difference (wind moves from high pressure to low pressure), and this starts the process all over again.
All of this describes diagram (4) which is the final answer. This diagram is a very simplified view and actual weather patterns are much more complicated.
-------------------
Side notes:
- Choice (1) can be ruled out because the surface wind should flow from the water toward the land. Also, the lake acts like a heat sink, so not much heat energy will cause warm air to rise compared to air on the land (which isn't that great a heat sink).
- Choice (2) can be ruled out because warm air should rise, and not sink.
- Choice (3) can be ruled out because cool air doesn't rise.
Pin point it. Find where you are by landmarks.
Answer:
The three similarities and difference between these two zones are as
Explanation:
- The dead zone is those that have a hyperoxic or low oxygen areas around the world caused by excessive nutrient pollution from human activities and other factors like salinization and sedimentation. The dead zones in the world are divided into Permanent, Temporary and seasonal.
<u>Some similarities and differences found among them are listed as </u>
- Maine dead zones: such as areas around these bays and seas have lots of acidic contents and dissolved salts.
- Algae bloom due to runoff and pollution: Runoff due to the overflowing of rivers and sediments brought by them create large and heavy algae growth.
- Estuary formation. Formations of estuary systems like at the mount of river and deltas formations.
Difference
- Located in Maryland, Virginia, and the Gulf of Mexico.
- The size of the Gulf of the Mexico dead zone is 22,730 sq kilometers and that of the Chesapeake bay is 320 kilometers.
- Economic impacts: They vary with ecological services etc. The greater impact has been seen in the gulf areas as 10 billion $ have already been wasted on cleaning the zone.
