WebThe stratosphere extends up to around 48 km above the surface, and together with the troposphere, they account for 99.9% of the Earth’s atmosphere. Mesosphere Temperatures in the mesosphere decrease with height from the stratopause up to the mesopause, at around 85 km. Temperatures at the mesopause vary from as low as -120 °C at high … Web24 mrt. 2024 · It is 11-12 miles (18-20 km) high at the equator, 5½ miles (9 km) at 50°N and 50°S, and just under four miles (6 km) high at the poles. As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height.
WebThis obviously means that it gives off heat into earth's atmosphere. If a 1km asteroid that has broken up into pieces were to hit earths surface, they would probably release a lot of heat too. Considering that an asteroid of 300m size has never been recorded to hit earth in our time, it could be assumed that a lot of heat is released by its impact. WebIt is also called the critical altitude, as this is the altitude where barometric conditions no longer apply. Atmospheric temperature becomes nearly a constant above this altitude. [5] On Earth, the altitude of the exobase ranges from about 500 to 1,000 kilometres (310 to 620 mi) depending on solar activity. [6]
