Question

study the diagram showing the range of temperature
in the earths layers.
what does the diagram show about earths interior?
the outer core is the hottest region.
the mantle is hotter than the outer core
the continental crust is the coolest region
the inner core is cooler than the lithosphere
temperature of earths layers

Explanation:

• Analyze each option:
• The inner core (at the greatest depth in the diagram) has the highest temperature value shown ($6,727^{\circ}C$), so the outer core is not the hottest.
• The mantle's temperature range (from surface - like near $1,000^{\circ}C$ to deeper parts) is lower than the outer core's ($2,727^{\circ}C$ and above).
• The continental crust (part of the lithosphere near the surface) has lower temperatures compared to deeper layers.
• The inner core is hotter than the lithosphere (which includes the crust and upper - mantle near the surface).

Answer:

The continental crust is the coolest region.
