From the planetary surface of the Earth, the average height of the troposphere is 18 km (11 mi; 59,000 ft) in the tropics; 17 km (11 mi; 56,000 ft) in the middle latitudes; and 6 km (3.7 mi; 20,000 ft) in the high latitudes of the polar regions in winter; thus the average height of the troposphere is 13 km (8.1 mi; 43,000 ft).
The troposphere is the lowest layer of Earth's atmosphere where weather occurs. It extends from the Earth's surface up to about 8-15 kilometers (5-9 miles) in altitude.
8 Νοε 2024 · troposphere, lowest region of the atmosphere, bounded by the Earth beneath and the stratosphere above, with its upper boundary being the tropopause, about 10–18 km (6–11 miles) above the Earth’s surface.
Troposphere. The troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.
20 Αυγ 2024 · The troposphere begins at the Earth's surface, but the height of the troposphere varies. It is 11-12 miles (18-20 km) high at the equator, 5½ miles (9 km) at 50°N and 50°S, and just under four miles (6 km) high at the poles.
Definition. The troposphere is the lowest layer of Earth's atmosphere, extending from the surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on geographical location and weather conditions. This layer is where almost all weather phenomena occur, making it crucial for understanding climate and atmospheric processes.
The troposphere contains approximately 75% of the atmosphere's total mass and almost all of its water vapor. Temperature decreases with altitude in the troposphere, averaging about 6.5 degrees Celsius per kilometer rise. The troposphere is where most weather phenomena occur, including clouds, rain, and storms, due to its dynamic nature.
