How far does the stratosphere extend from the troposphere?
50 kilometers
The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.
What layer extends from 300 km to more than 600 km?
THERMOSPHERE
THE THERMOSPHERE EXTENDS UP TO 600 Km ABOVE EARTH. THIS IS THE LAYER WHERE THE SPACE SHUTTLE AND SPACE STATION ORBITS. THE GASES OF THE THERMOSPHERE BECOME INCREASINGLY THINNER.
What is the average distance of troposphere?
The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles. At the equator it is around 11-12 miles (18-20 km) high, at 50 °N and 50 °S , 5½ miles and at the poles just under four miles high.
What layer extends from 90 km to 300 km?
thermosphere
The thermosphere extends from 90 km to 300 km (56 mi. to 186 mi.). It is the hottest layer of the atmosphere at 1,500°C (2, 732°F). Astronauts orbiting Earth in the space I station spend their time in this layer.
What is the average height of troposphere in KM?
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; …
How far is space from Earth in KM?
What is the Kármán Line? Experts have suggested the actual boundary between Earth and space lies anywhere from a mere 18.5 miles (30km) above the surface to more than a million miles (1.6 million km) away.
How big is the troposphere in miles and kilometers?
The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth.
Which is the best description of the stratosphere?
Stratosphere. Located between approximately 12 and 50 kilometers (7.5 and 31 miles) above Earth’s surface, the stratosphere is perhaps best known as home to Earth’s ozone layer, which protects us from the Sun’s harmful ultraviolet radiation.
Which is the lowest layer of the troposphere?
➤ The PLANETARY BOUNDARY layer is the lowest part of the Troposphere, where temperature, moisture, and the wind is influenced by friction. ➤ The TROPOPAUSE is the top most of the Troposphere, which is the border between the Troposphere and Stratosphere.
How tall are the layers of the atmosphere?
Earth’s Atmospheric Layers. Diagram of the layers within Earth’s atmosphere. The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles).
