Answer

Brief Explanations:

  1. Analyze each option:
    • Option 1: The outer core (depth around 2900 - 5150 km) has a temperature up to 4727 °C? No, the inner core (deeper than 5150 km) reaches higher temperatures (6727 °C), so outer core is not the hottest.
    • Option 2: Mantle (depth 410 - 2900 km) has max temp ~2727 °C, outer core (2900 - 5150 km) has higher temp (up to 4727 °C), so mantle is not hotter than outer core.
    • Option 3: Continental crust is part of the lithosphere (shallowest layer, depth < 410 km). The shallowest regions (crust) have the lowest temperature (since temperature increases with depth), so continental crust is the coolest region.
    • Option 4: Inner core (depth > 5150 km) has very high temperature (6727 °C), lithosphere (shallow, includes crust) is cooler, so inner core is not cooler than lithosphere.

Answer:

The continental crust is the coolest region.
