The coldest place in the world
The coldest place in the world should be Oymyakon, which is covered by snow and ice all year round, and at the lowest temperature can reach more than -70 degrees Celsius, which even makes many local residents freeze to death. Living in such an environment can be a kind of torture, but the locals still live here for generations. Because this is all permafrost, and the surface temperature is very low, so when the locals build their houses, they will build them overhanging, and the windows and doors will be heavily covered, so that the temperature inside the house can rise some.
The hottest place in the world
The hottest place in the world would be Coober Pedy, Australia. People here build their houses underground, because in summer, the temperature can reach more than 50 degrees, and the highest time even up to 60 degrees. Such hot weather, if living above ground, then soon will be heatstroke and dehydration, so the local people will be built underground, so as to relieve the heat, so that during the day, the ground basically can not see people.
The difference in temperature between the two is more than 120 degrees, nature is really amazing. But such a year-round high temperature and year-round low temperature areas, really not the average person can adapt to, can only show that people's adaptability is really strong.
