The term "earth tempreche" doesn't seem to be a recognized term. It might be a misspelling of "earth temperature."

If you meant earth temperature, it's a broad concept with various interpretations:

* Average global temperature: This refers to the average temperature of the Earth's surface, currently estimated around 14.9 degrees Celsius (58.8 degrees Fahrenheit). It's influenced by factors like solar radiation, greenhouse gases, and ocean currents.

* Surface temperature: This refers to the temperature at the Earth's surface, which varies widely depending on location, time of day, season, and altitude.

* Internal temperature: The Earth's interior gets progressively hotter as you go deeper, reaching temperatures of around 5,200 degrees Celsius (9,392 degrees Fahrenheit) at the Earth's core.

Please clarify what you meant by "earth tempreche" so I can provide a more specific answer.
