What is the altitude of each layer of the atmosphere?
Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles)
What is the altitude of the thermosphere?
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.
What’s the hottest layer of Earth?
The inner core
The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick!
At what altitude does the mesosphere end?
The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet.
What is the altitude of the mesosphere?
about 50 and 80 km
mesosphere, region of the upper atmosphere between about 50 and 80 km (30 and 50 miles) above the surface of the Earth. The base of the mesosphere is defined as the temperature maximum existing at the top of the stratosphere, with the boundary between the two regions usually called the stratopause.
What is the relationship between temperature and altitude in the exosphere?
Temperatures increase again with altitude in the thermosphere, which begins about 80 kilometers (50 miles) above the Earth. They can rise to 2,000°C (about 3600°F). The exosphere begins at 500 to 1,000 kilometers (about 310-621 miles) and the few particles of gas there can reach 2,500°C (about 4500°F) during the day.
What is the thinnest layer of the Earth?
Discuss with the whole class what the relative thicknesses of the layers are — that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer.
What is the altitude of the stratosphere?
around 31 miles
Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth’s surface. This layer holds 19 percent of the atmosphere’s gases but very little water vapor. In this region the temperature increases with height.
What is the altitude of the mesopause?
This layer extends from the stratopause at an altitude of approximately 160,000 ft to the mesopause at approximately 260,000–80,000 ft above sea level. Temperatures drop with increasing altitude to the mesopause that marks the top of this middle layer of the atmosphere.
Why is thermosphere the hottest layer?
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere.
How high up is the exosphere?
The thermosphere includes the exosphere and part of the ionosphere. •Exosphere: The exosphere is the outermost layer of the Earth’s atmosphere. The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km).
What is the density of the exosphere?
The exosphere is about 250 miles above the earth’s surface. The density of gases that fill the exosphere is about a million-millionth of the density at the earth’s surface.
What are facts about the exosphere?
Interesting Exosphere Facts: The exosphere begins at a distance of 311 to 621 miles from the earth’s surface, and ends at approximately 6200 miles from the earth’s surface. Although the exosphere is the most distance layer of earth’s atmosphere it is the layer that is the planet’s first line of defense against the sun’s rays.
How big is the exosphere?
The exosphere is the very edge of our atmosphere. This layer separates the rest of the atmosphere from outer space. It’s about 6,200 miles (10,000 kilometers) thick. That’s almost as wide as Earth itself. The exosphere is really, really big. That means that to get to outer space, you have to be really far from Earth.
