HOPE THIS HELPS! <3
Explanation:
Considering the composition of earth, there are three main layers whose composition and temperature. Here as follows-
<em>a) Inner Core – The inner core is made up of iron and nickel and has a temperature of 7200 degree Celsius.
</em>
<em>
</em>
<em>b) Molten Outer core – It is also made up of iron and nickel and has a temperature of 4300 degree Celsius.
</em>
<em>
</em>
<em>c) Inner mantle – It is semi rigid and made up of silicon, oxygen, magnesium, iron, aluminum, and calcium and has a temperature of 3700 degree Celsius
</em>
<em>
</em>
<em>d) Crust – It is made up of water, basalt and granite and has a temperature of 0 degree Celsius

Looking at the composition and the temperature of the different layers, it shows that any terrestrial planet has highest temp in the core and the least at its crust!
