How does convention occur in the troposphere

The troposphere is the region that covers a vertical height of about 10-15 km from the surface of the earth. In this region as the height increases, temperature decreases. This means that within the troposphere, the temperature and height are inversely proportional to each other.

The different parts of the earth receive different amounts of sunlight. The land area gets heated up more readily in comparison to the oceans because it directly absorbs the heat energy. Whereas the surface of the ocean acts as a reflector, reflecting heat. So it warms and cools at a much slower rate. Due to this unequal heating of the earth's surface, the wind is generated.

The air molecules are densely packed near the earth's surface and loosely packed in the upper part of the troposphere. So due to the high heat, the air near the surface gets heated up, becomes less dense and rises up. As it reaches the upper part of the troposphere, it eventually cools and sinks. This continuous motion of air molecules forms a convection current within the troposphere region.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
