The Sun's outer atmosphere contains highly ionized atoms that can only form at a temperature of millions of degrees. Some extra source must deposit energy into the corona to create the steep temperature gradient. This source must also balance energy losses through radiation emitted into space, ...
The mesosphere is the middle layer of Earth's atmosphere, as the prefix "meso-" suggests. It is located between the stratosphere below and the thermosphere above at an altitude of about 50 - 85 km. Though relatively deep, it contains only about 0.1% of the atmosphere's mass, meaning the...

An additional unknown acceleration mechanism is required and likely relates to magnetic fields in the solar atmosphere." So sun escape velocity may not be so important since there is apparently an active force propelling the wind away from the sun. Mar 3, 2024 #7 jefo 10 2 renormalize ...
The HyDR on commercial direct-reduction hematite pellets was conducted at 900 °C under a pure hydrogen atmosphere using a thermogravimetry setup. After isothermal holding at this temperature for approximately 690 s, the reduction degree reached ~99%, suggesting completion of reduction, Fig. ...
When liquid water evaporates, it becomes water vapor and enters the atmosphere. This process is essential to kickstart the water cycle, a continuous movement of water on, above and below the surface of the Earth. Evaporation occurs when heat from the sun causes water from oceans, rivers, ...
