Answer:

Aloft high pressure develops in cold air regions while low pressure develops in warm air regions

Explanation:

A thermally-driven circulation, or thermals are the movement of warm air that move to a higher level due to the buoyancy forces acting on them. That is due to the difference in densities between the warmed and cool air

Given that pressure = Density, <em>ρ</em> × Gravity, <em>g </em>× Height, <em>h</em>, we have that decrease in pressure (low pressure) is due to low density, therefore, the warm air having low pressure, moves upwards, due to their low density

Therefore, the best option is aloft, (as we move higher), high pressure develops in cold air regions while low pressure develops in warm air regions

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.

Answer:

The movement of continents has affected weather patterns by creating mountain ranges and changing the location of the continents.

Explanation:

The movement of continents, or rather the movement of tectonic plates, has had, has, and will continue to have a huge impact on the weather patterns on Earth. One of the things that are among the most influential is the creation of mountain ranges and the changing locations of the continents.

The creation of mountain ranges alters the movement of air masses, meaning that it is a process that influences the amount of precipitation, as well as temperature distribution in the areas where they are found. The changing locations of continents are even more influential. This determines the size of oceans and seas and because of that the ocean currents as well. If there is more landmass around the poles then the climate will be colder and drier on a global level and the sea levels will be lower, but if landmass is lacking around the poles then the global climate will be warmer, wetter, and the sea levels will be higher.
