The thermosphere is the fourth layer of the Earths atmosphere that absorbs the suns radiation, making it very hot. The atoms are so far away that collisions rarely happen, and they cannot behave like a gas. The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. Without making any statement about the cause of this heating, I decided to calculate the cooling by (black body) radiation, and that way define the energy amount needed to maintain this temperature. The thermosphere is very hot, with temperatures up to 2,000 degrees Sign up to receive exclusive deals and announcements, Fantastic service, really appreciate it. The troposphere contains almost all of the mass of the atmosphere.

Despite the high temperature, you would not feel warm in the It's more than Sun, which has a Power of $3.84610^{26} W$ If you were to hang out in the thermosphere, though, you would be very cold because there arent enough gas molecules to transfer the heat to you. Aeroplanes and other modern aircraft cant fly above 50 kilometres because the lower air density at these altitudes doesnt allow for sufficient lift. We can be in absolutely no doubt that a critical driver behind this warming trend is carbon dioxide emissions from the burning of fossil fuels, said Dr Leslie Mabon, lecturer in environmental systems at The Open University. At present, the only vehicles that can travel in this layer of our atmosphere, at an altitude between 50 and 80 kilometres, are rockets destined for space. Temperature of the Exosphere The exosphere is closer to the Sun than the other layers of the atmosphere and therefore is the warmest. https://www.wsj.com/articles/sun-tired-hot-weather-heat-bb750670.

The high average temperature of its diffuse particles is strongly influenced by whether the Sun is shining on it, and by how active the Sun is at any given time. When the Sun is very active and emitting more high energy radiation, the thermosphere gets hotter and expands or puffs up. Convection requires a dense-ish fluid, which does not exist in the thermosphere to move the heat, so it's all up to conduction. The line marking the boundary of outer space is found in the lower thermosphere, at 100 km altitude. Atoms and molecules in the thermosphere are excited by radiation from outer space. Connect and share knowledge within a single location that is structured and easy to search. this part of the atmosphere is still so thin than an object placed Ultraviolet radiation, visible light, and high-energy gamma radiation are all absorbed by the thermosphere, which causes the few particles present to heat up considerably. above the Earth's surface, contains the ionosphere, which is the region of the atmosphere that is filled with charged particles. a result of UV absorption.

The faster moving molecules will slow down and the slow moving molecules will speed up. Europe is not particularly affected by El Nio events directly, therefore it is likely the high-pressure system and climate change that are the main contributors to this heatwave event, said Dr Melissa Lazenby, lecturer in climate change at the University of Sussex. It also depends on how active the Sun is during its 11-year sunspot cycle. They help address the question of why the thermosphere is so hot, while the rest of the atmosphere due to the large distance from the Sun is cold.
