3 maj 2022 · The five main layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Mainly, temperature determines the altitude of these layers. The atmosphere is fluid and changes according to season, day/night cycle, and other factors, so the lower and upper limits of each layer shift.
6 paź 2023 · Stratosphere. Temperature: -60°F (-51°C) near the tropopause to 5°F (-15°C) near the next layer. Lies just above the troposphere, extending up to 31 miles (50 km) high. It is the part of the atmosphere that contains the ozone layer, which is essential for our survival as it blocks the harmful UV rays of the Sun from reaching us.
Earth's atmosphere is composed of a series of layers, each with its own specific traits. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The exosphere gradually fades away into the realm of interplanetary space.
The stratosphere starts at an altitude of ~6 miles (10km) and extends up to ~30 miles (50km). It is so named because the stratified layers within it have a temperature profile that increases with altitude. The stratosphere holds the ozone that absorbs harmful UV radiation and prevents it from reaching the surface.
In some layers, temperature increases with altitude and in others it decreases. The temperature gradient in each layer is determined by the heat source of the layer. Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.
20 sie 2024 · Five distinct layers have been identified using thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical composition, move.
1 gru 2020 · Stratosphere: 14 to 64 km (9 to about 31 miles) Unlike the troposphere, temperatures in this layer increase with elevation. The stratosphere is very dry, so clouds rarely form here. It also contains most of the atmosphere’s ozone, triplet molecules made from three oxygen atoms. At this elevation, ozone protects life on Earth from the sun’s ...
