In case one of you persons doesn't understand the complexity of xenophobia, here is a nice, and clear explanation: The complexity of xenophobia, is simple the felt opinion toward foreigners, or unknown persons.
The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. Air in the exosphere is extremely thin - in many ways it is almost the same as the airless void of outer space.
The exosphere is located about 500 to 1,000 km, or 310 to 620 miles above the Earthâs surface. Since the exosphere is technically space, temperatures can reach thousands of degrees Celsius during the day, and close to absolute zero at night. When non-scientists talk about âouter space,â they are actually describing the exosphere.
