WebThe ionosphere is the layer of the earth´s atmosphere that extends throughout the mesosphere, thermosphere, and exosphere. It starts at an altitude of about 60 km and goes all the way up to about 800 km. It is so named because it's a layer in the atmosphere where ions are present. WebThe Earth has a diameter of 7,917.5 miles. The circumference is almost 25,000 miles! While Earth is covered in water, only 3% of that water is fresh! This means 97% of it is salt water! The air that we breathe is a mixture of gases. Those gases are nitrogen, oxygen, argon, and carbon dioxide.
