Question
the tempurture of the crust
Answers
GPT-5 mini
Do you mean the Earth’s crust, a pizza/bread crust, or something else?
Brief summaries while you decide:
- Earth’s crust: temperature depends on depth and location. Near the surface it matches air/soil temperature (−50°C to +50°C depending on climate). Temperature increases with depth at the geothermal gradient (roughly 20–30°C per km on average), so a few kilometers down it’s hundreds of °C; at the crust–mantle boundary it can range from a few hundred up to ~900°C or more in active regions.
- Oceanic crust: thinner (∼7–10 km) and generally hotter at a given depth near mid‑ocean ridges; older oceanic crust cools and is colder at the same depth.
- Pizza/bread crust: oven temperatures are typically 180–250°C for home ovens, and 400–500°C for wood‑fired pizza ovens.
Tell me which you meant and I’ll give more specific numbers and context.
