SUMMARY

The average temperature of the Earth, considering the entire planet rather than just the surface or core, is estimated to be around 15 degrees Celsius (59 degrees Fahrenheit). This value is essential for modeling hypothetical scenarios, such as calculating the cooking effect on an object traveling through the Earth. The discussion highlights the complexity of deriving an accurate average temperature due to various factors like seasonal changes and geological layers. Users are encouraged to explore existing resources for more detailed information on Earth's temperature profile.

PREREQUISITES
  • Understanding of Earth's geological layers, including the crust, mantle, and core.
  • Basic knowledge of thermodynamics related to temperature distribution.
  • Familiarity with scientific estimation techniques.
  • Awareness of resources for Earth science data, such as ehow.com and enchantedlearning.com.
NEXT STEPS
  • Research the temperature gradient from the Earth's core to the surface.
  • Explore methods for estimating average temperatures in geological studies.
  • Learn about the impact of seasonal variations on surface temperature measurements.
  • Investigate scientific literature on Earth's thermal properties and heat flow.
USEFUL FOR

Students, geologists, climate scientists, and anyone interested in understanding Earth's thermal dynamics and temperature estimations for scientific modeling.

Hey guys,

I'm looking for the average temperature of the earth. I don't appear to be able to find one. If anyone knows the average value, or has seen it somewhere, I'd appreciate it if you could point me in the right direction, since I don't really want to calculate it myself. Oh, and I don't mean the average temperature of the surface or the core, but the whole entire planet in case anyone thought otherwise.

Thanks

Simon

Calculating the average temperature of the Earth would be very complex. You have to factor in the time of year, positions, and much more.
 
I don't need an exact value, just sort of, a rough estimate.
 
That's the average temperature of the Earth's surface. Simon is looking for the volumetric (or similar) average of the entire planet.

Why do you want to know, since you don't want to do it yourself?

Purely because I have been set a hypothetical problem where an object that is to be "cooked" must travel through the entire earth. And since I've been asked to model the rareness (how well its been cooked) of the object, I need a rough idea of the average temperature of the Earth from core to external (outer extremity) mantel. The only thing I'm missing is an idealised value so I can complete the calculation since I have derived the rest.

Edit: That and I am curious/ was interested to see if anyone's done this before. If not I might have a go at making a rough estimate myself if no one else has a rough idea or has done a rough estimate before hand.

Scroll down to the graphic "Layers from crust to core".

Thanks, that's perfect Evo. I can work the rest out from that.
