Earth's atmosphere also play a vital role in regulating the temperature by providing a blanket of gases that not only protects us from excessive heat and harmful radiation from the sun, but also traps heat rising from the Earth's interior, keeping us warm. The average temperature on Earth is about 61 degrees F (16 C).But temperatures vary greatly around the world depending on the time of year, ocean and wind currents and weather conditions.
