<span>The cylinder is in a stable equlibrium. The fact that the center of gravity is not that far from the actual geometrical center the cylinder will continue to return to it's starting position even with it being somewhat displaced on the table top.</span>
When the air is heated, it rises from the earth's surface and it mixes with the winds constantly.
Answer: Troposphere
Explanation:
Clouds form in the troposphere, which is the layer of the atmosphere that is closest to Earth.
The process of cloud formation starts with warm, moist air that rises because warm air rises. This air cools as it rises. The temperature of the rising air drops until the air can no longer rise further and it expands into the troposphere. The water vapor in the air then condenses to form water droplets which form clouds.
