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.
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.
Earth’s atmosphere consists of five distinct layers that are distinguished by temperature gradients—the layers alternate between having temperatures that increase or decrease with altitude. The five principal layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
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.
3 Μαΐ 2022 · The troposphere is the layer of the atmosphere that contacts the Earth’s surface. Its average height is 12 km (7.5 mi; 39,000 ft), but it is thickest at the equator and also varies according to weather.
