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.
the convection currents will be set in motion because the heat from the mantle rises and causing it to change Earth's density & force of gravity
The convection currents will cease to exist. This may cause some warmth to leave Earth's surface.
It would likely slow continental drift and reduce volcanic activity, especially island building over mantle hot spots.

Convection current Convection current
The convection currents are a result of heat from the interior of the Earth. The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
Convection
Same as with weather, but in stead of air, you've got molten rock: magma. Hotter magma is less dense than cooler magma (although they're both still quite hot enough to turn you to a crisp, of course), and thus rises towards the surface, where it releases heat into the crust. Having cooled down, it descends towards the core again, where it soaks up new heat, so that it starts to rise once more.

Convection currents in water (or any fluid) are the movement of the water caused by a difference in temperature between the upper and lower layers of the water. As water is heated it becomes lighter than cooler water so it floats up. Conversely, as water is cooled it get heavier so it sinks. Assume the weather has been warm and the water in a pond is warm, then a cold spell comes through. The cold air cools the water at the surface causing it to sink. As it goes down into the warmer water it's heated and as more cooled heavier water sinks it pushes the newly warmed water up. This continuing process will eventually cause this original cooled and rewarmed water to reach the surface where it will be cooled and sink again and the process repeats until the entire pond is at the same temperature. This sinking and rising is called convection and the moving water is called convection currents.
because mars is a lot smaller than the earth (mars is about the same size as the earth) it is said that the interior of mars has cooled. Therefore convection of the asthenosphere is not possible and continental drift does not occur. We think the earth is headed in the same direction as mars and the earths interior will eventually cool to a solid.
This describes what happens in a convection cycle.
Convection currents move the magma around in circles up and down as it gets cooled and heated. And the plates move on top of them.
