Which is the correct sequence of height of tropopause (in km) over polar areas, over middle latitudes, and over the equator?

Correct option is A

The height of the tropopause varies depending on the latitude. In polar regions, the tropopause is at its lowest, approximately 9 km above the Earth's surface. Over the middle latitudes (temperate zones), it is slightly higher, around 11 km, and at the equator, where the troposphere is most heated and active, the tropopause reaches its highest height of about 16 km. This variation is mainly due to the temperature gradient and the atmospheric dynamics in different regions of the Earth.

Information Booster:

1. The tropopause is the boundary layer between the troposphere and the stratosphere.
2. In polar regions, the atmosphere is colder, causing the tropopause to be lower.
3. At the equator, the tropopause is higher due to intense heating and convection.
4. Middle latitudes experience moderate temperatures, resulting in an intermediate height for the tropopause.
5. The height of the tropopause also affects weather patterns and jet stream locations.
