In descending order of abundance what are the layers of earth's atmosphere?

Answer 1

In ascending order of altitude, these are the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere.

Answer 2

In ascending order of altitude, these are the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere.

Answer 3

The atmosphere is the gaseous envelop that surrounds the earth and is held in place by gravity. By decreasing order of abundance, the layers of the earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere and ionosphere.

Answer 4

The lowest is the troposphere, which is the layer that provides most of our weather. It contains about 80% of the Earth's air, but extends only to a height of about 11 miles (17 kilometers) at the Equator and less at the Poles.

Above the troposphere is the stratosphere. It extends to a height of about 30 miles (50 kilometers) and includes the ozone layer.

Above the stratosphere is the mesosphere. Meteors generally burn up in this layer, which extends to a height of about 52 miles (85 kilometers).

Above the mesosphere is the thermosphere. It extends to about 430 miles (690 kilometers). The International Space Station and other low orbit satellites orbit within this layer. Space is widely accepted now as starting at 100km above sea level.

The highest layer is the exosphere. This part of the Earth's atmosphere extends outward until it interacts with the solar wind. It ranges from 620 miles (1,000 kilometers) to 6,214 miles (10,000 kilometers) above the surface, where it merges with interplanetary space.
1. Troposphere (8-18km above Earth's surface) 2.Stratosphere (50km above Earth's Surface) 3. Mesosphere (50-85km) 4.Thermosphere (85-450km) 5.Exosphere (450-10,000km)
Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere, Exosphere.
