The answer to this question is letter B. Convection.

<span>>Mantle's convection is thought to make up about eighty percent of the internal heat flow to the surface, while the remainder originates in the crust.
</span><span>>The main means of heat transfer is convection. This process requires that the substance can behave like a "fluid", and the earth's mantle does.</span>

The answer is

Convection currents raise the less dense hot material from the center to the cool crust and material from the cool (dense) crust settles down to the core to be heated again.

The data table above includes the distance each planet is from the sun. Students in an Earth science class were asked to explain

Serga [27]

Student 4

Explanation:

The sun has less gravitational pull on Neptune because it is farther away. Gravity is the force by which a planet or other body draws objects towards its center.
Gravity keeps all the planets in its position and allows it to move in its orbit.
The force of gravity is inversely proportional to the distance between two objects.

So when the distance increases, the force weakens. Since Neptune approximately 4.8 billion kilometers away from the sun, its gravitational force is very less.
