Question

What does the diagram show about Earth’s interior?

1.The outer core is the hottest region.
2.The mantle is hotter than the outer core.
3.The continental crust is the coolest region.
4.The inner core is cooler than the lithosphere.

Answer 1

The answer would be 3. The continental crust is the coolest region

All you need to do is look at the statements and compare them to the graph

Hope this helps

Answer 2

Hello there!

According to the diagram, 3. The continental crust is the coolest region at 0km-410km; this layer is also called the lithosphere.

Here are the reasons why the other statements are false.

Statement 1. The outer core is not the hottest region because the inner core from 5150km-6370km has a temperature of 4727°C-6727°C while the outer core from 2900km-5150km is colder at a temperature of 2727°C-4727°C.

Statement 2. The mantle is not hotter than the outer core because according to the diagram, the mantle from 660km-2900km has a temperature between 1627°C-2727°C while the outer core from 2900km-5150km has a temperature between 2727°C-4727°C. Therefore, the outer core is hotter than the mantle.

Statement 4. The inner core is not cooler than the lithosphere because the lithosphere (0km-410km) has a temperature of 0-1000°C while the inner core (5150km-6370km) is hotter at 4727°C-6727°C.

Below are the labels of your diagram to help you.
