We would not be alive.

No, both conditions would make the earth cooler.
The study of the earth's interior is important for man to understand his environment. It also helps to predict events that may occur on the earth's surface.
Smaller.
False.
If the Sun's temperature were much colder and it were much smaller Earth would no longer support human life
The earth would be quite a bit cooler and darker than it is now.
the earth would die
In reality, the interior of the Earth is slowly cooling. In human time perspective, however, this cooling has no impact.
We would not be alive.
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.

Have a lower average density.
If the mantle of the earth interior were to cool down the convection currents and plate tectonics would stop. That would mean that there would be no more earthquakes or volcanoes.
