The outermost layer of the atmosphere containing very little gas.

The part of the Earth's atmosphere lying between the mesosphere and the exosphere. In the thermosphere, temperature rises rapidly with height, because of absorption of high-energy solar radiation, and collisions with high energy particles. With the exosphere, forms the outer part of the atmosphere.

Thermosphere is the layer of the earth's atmosphere extending from the top of the mesosphere (80 km - 90 km above the surface) to about 500 km. It is characterized by a rapid increase in temperature with increasing altitude up to about 200 km, followed by a leveling off in the 300 km - 500 km region.

The atmospheric zone beginning about 53 miles (85 kilometers) up and characterized by a significant rise in temperature with increased altitude

The highest atmospheric zone; a region of hot, dilute gases above the mesosphere extending out to about 1600km (1,000 mi) from the earth¡¦s surface.

The region of the earth's atmosphere above the mesopause , starting at 80 km (50 mi) altitude, where the air temperature increases with altitude. The thermosphere extends outward toward space and includes the exosphere and most or all of the ionosphere.

The layer of Earthâ€(tm)s atmosphere directly above the mesosphere, and below the exosphere. It begins about 85 km above the surface, and stretches to between 500 and 1,000 km above it.

The outer layer of the atmosphere including the exosphere and most or all of the ionosphere. Characteristically, the temperature steadily increases with increasing altitude.

outermost layer of the atmosphere where temperature increases with altitude due to receiving intense solar radiation

The highest layer in the atmosphere, where atoms absorb solar energy resulting in warming of the air to as high as 3,600 F.

The Earth atmosphere between 120 and 250 to 400 km (depending on the solar and geomagnetic activity levels), where temperature has an exponential increase up to a limiting value Texo at the thermopause. The temperature Texo is called the exospheric temperature.

The layer of the atmosphere lying between 100 - 400 km altitude. More information here.

The atmospheric layer between the mesosphere and the exosphere.

A layer in the earth's atmosphere, above the mesosphere, heated by X-rays and ultraviolet radiation from the Sun.

A thermal classification, it is the layer of the atmosphere located between the mesosphere and outer space. It is a region of steadily increasing temperature with altitude, and includes all of the exosphere and most, if not all, of the ionosphere.

The atmospheric layer above the mesosphere (above about 85km) where the temperature increases rapidly with height.

Atmospheric layer above the mesosphere (above 80 kilometers) characterized by air temperatures rising rapidly with height. The thermosphere is the hottest layer in the atmosphere. In the thermosphere, gamma, X-ray, and specific wavelengths of ultraviolet radiation are absorbed by certain gases in the atmosphere. The absorbed radiation is then converted into heat energy. Temperatures in this layer can get as high as 1300-1800° Celsius.

the layer of the atmosphere located above part of the ionosphere (starting at the coldest part of the atmosphere) and below outer space; it consists of the exosphere and part of the ionosphere.

The thermosphere is a thermal classification. It is the layer of the atmosphere located between the mesosphere and outer space. In the thermosphere, temperature increases with altitude. The thermosphere includes the exosphere and part of the ionosphere.

The atmospheric shell extending from the top of the mesosphere to outer space. It is a region of more or less steadily increasing temperature with height, starting at roughly 100 km. The thermosphere includes, therefore, the exosphere and most of the ionosphere.

The outermost layer of the atmosphere, where gas molecules split apart into ions.

The thermosphere is the layer of the earth's atmosphere directly above the mesosphere and directly below the exosphere. Within this layer, ultraviolet radiation causes ionization. (see also: ionosphere). It is the fourth atmospheric layer from earth.
