The troposphere contains about 85% of the atmosphere’s total mass. Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate. The chemical composition determines the air quality.
Its functions to act as a transitional medium to a zone under the influence of gravity. It also helps the atoms to escape from the atmosphere to outer space. Unlike other atmospheric layers, it is the only layer of the atmosphere that has a definite shape.
Mesosphere – The layer above stratosphere at a distance between 50 – 80km above the earth’s surface. This layer is very cold and burns most of the meteors preventing them from reaching the earth’s surface. Thermosphere – The layer above the mesosphere at a distance between 80 – 320km above the earth’s surface.
10 Facts about Exosphere Earth atmosphere is divided into many distinct layers. … The exosphere is the most outermost layer of earth’s atmosphere. This layer start at 500 km above the earth’s surface and goes about 10000 KM. The air is extremely thin in exosphere.
Ionosphere: is the lower layer of the thermosphere.This is where earth’s communication is located along with the aurora borealis.Exosphere: is the upper layer of the thermosphere. Satellites are found in this layer.
Earth atmosphere layers Earth’s atmosphere consists of five main layers from lowest to highest: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
gravityThe atmosphere is held around the Earth by gravity.
The atmosphere of the Earth is divided into four layers: troposphere, Stratosphere, Mesosphere and Thermosphere, and they are separated based on temperature.
(4.6 billion years ago) As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere. After about half a billion years, Earth’s surface cooled and solidified enough for water to collect on it.
Earth’s atmosphere is a jacket of gases that surrounds our planet. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens.
