If earth stopped spining,how could wold the darker side

According to one Gizmodo writer in the article “Dark Side of the Earth: What would happen if our planet became tidally locked? by Esther Inglis-Arkell”

One side of the planet cooks while the other freezes. Water on one side is vapor, and on the other side is ice. If there is any appreciable amount of life on the surface of the planet, it has to be in the twilight strip of land between the two halves.

But it's not as simple as getting the temperature right. If our atmosphere permanently lost the heat of the sun, it would first turn into a denser gas, then condense into a liquid, and then further condense into solid ice. Meanwhile, air that is constantly exposed to light — or that is heated by a ground that is constantly exposed to light — will heat up and expand. Although it's doubtful that the atmosphere on the dark side of the planet would get to solid form, it would certainly keep condensing and leaving a vacuum to suck in the expanding hot air from the other side. This might make for circulation of atmosphere that would make the planet livable, but it would also lead to hellish storms, as the atmosphere from the light and dark side of the planet essentially switched sides continually.And those winds may bring some very, very nasty things with them. Even geologists foresee major problems with tidally locked planets. Rock and soil erodes differently when it's exposed to different levels of light. The cool side of the planet is preserved fairly well, but the lit side of the planet is stripped of its oceans and made to face burning sun and scrubbing wind every day. It will erode faster, and rocks that might have turned to terrestrial sand in a climate with night and day may be vaporized, picked up by the wind, or dissolved in water vapor to go airborne. Life, if it manages to struggle along on such a planet, will either be underground or very, very hardy.
