What is the convection pattern between 30°S and 30°N latitude?(1 point)
Responses
Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
Cooler air rises and moves toward the equator, then warms and falls and moves away from the equator.
Cooler air rises and moves toward the equator, then warms and falls and moves away from the equator.
Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.
Hotter air rises and moves away from the equator, then cools and falls and moves back to the equator.
Cooler air rises and moves away from the equator, then warms and falls and moves back to the equator.
Cooler air rises and moves away from the equator, then warms and falls and moves back to the equator.
Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
The correct answer is:
Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
The correct answer is: Hotter air rises and moves toward the equator, then cools and falls and moves away from the equator.
To understand the convection pattern between 30°S and 30°N latitude, we can apply the principles of global atmospheric circulation. This pattern is known as the Hadley Cell.
1. The region between 30°S and 30°N latitude is referred to as the tropics. It experiences a surplus of solar radiation, making it relatively hotter compared to other latitudes.
2. At the equator, the intense solar heating causes the air to rise, forming an area of low pressure. As the air rises, it cools and condenses, creating a band of clouds and rain known as the Intertropical Convergence Zone (ITCZ).
3. As the air rises near the equator, it moves poleward, both to the north and south. This is due to the conservation of angular momentum, which causes the air to deflect horizontally as it moves toward higher latitudes.
4. As the air moves poleward, it gradually cools and begins to descend around 30°N and 30°S latitude. This descending motion creates areas of high pressure known as the subtropical highs.
5. The descending air diverges at the surface, moving toward the poles at the upper levels and back towards the equator at the lower levels. This creates the trade winds, which blow from the east in both hemispheres towards the equator.
So, the convection pattern between 30°S and 30°N latitude involves hotter air rising near the equator, moving poleward, cooling, and then descending around 30°N and 30°S latitude.
