To what depth below earths surface do you have to go before the pressure and temperature cause rocks to melt?
At depths of 50 to 200 km below Earth's surface rocks will melt.
Asked in Geography
How high can the altitude be before you burn in the heat of the earths atmostsphere?
When the altitude on Earth increases, the temperature decreases. The reason spacecraft are incredibly hot upon re-entry into the Earth's atmosphere is due to the friction of the molecules in the atmosphere on the spacecraft, which are traveling at extremely high speeds. ...

Asked in Astronomy
Why does meteros disappears before reaching the earth?
Not all meteors disappear before reaching the earth. The friction they feel as a result of rubbing with the molecules of the earth's atmosphere cause them to burn up. However, a few larger ones will make it to the earths surface. ...
