Question

Which sentence provides evidence that heat travels from Earth’s mantle up to its crust?

a) Earth’s atmosphere is warmer during the day than at night.
b) Earth’s outer surface is cooler than its interior layers.
c) Rocks and other objects on Earth’s surface heat up quickly in the afternoon sun.
d) The core of Earth is solid, but the layer just beneath Earth's crust is molten.

Answer 1

The answer is option B.

Step-by-step explanation:

There are a few certainties that verify this announcement: the nearness of fountains of liquid magma that oust greatly hot material from the Earth's inside: boiling water springs because of its profound starting point in the hull; mines that are extremely profound can likewise demonstrate that the earth gets hotter as we get into its inside. Warmth streams to the outside layer in various routes however: by conduction, radiation and convection.

Answer 2

"b) Earth’s outer surface is cooler than its interior layers."

There are several facts that attest this statement: the presence of volcanos that expel extremely hot material from the Earth's interior: hot water springs due to its deep origin in the crust; mines that are really deep can also prove that the earth gets warmer as we get into its interior. Heat flows to the crust in different ways though: by conduction, radiation and convection.
