The layer of the Earth with the lowest temperature is the crust. The Earth's crust is the outermost layer, and temperatures can vary significantly depending on location. However, in general, the temperatures in the crust, especially in places like the polar regions, can be much lower than in the deeper layers of the Earth, such as the mantle and the core, which are much hotter due to the pressure and heat generated from radioactive decay and the Earth's formation.
