Select the correct answer from each drop-down menu. Based on what you know about the relative temperatures of Earth's geological layers, what can be said about the crust, mantle, and core of other terrestrial planets? For any terrestrial planet, the would be the hottest layer.

For any terrestrial planet, the core would be the hottest layer. The core, being composed primarily of metals like iron and nickel, experiences immense pressure, which leads to very high temperatures, often exceeding those found in the crust and mantle. Interestingly, the crust of terrestrial planets varies significantly. For example, Mars has a crust that is mostly basaltic, while Earth’s crust is more diverse with continental and oceanic components. This diversity affects geological activity and surface features on each planet, illustrating how crust composition can influence a planet's characteristics!
