Imagine the mantle (the hot bit under the Earth's crust), like a lava lamp. The hot magma, which has been heated right down at the very bottom, near the outer core, is less dense then the rest of the magma. It rises, like your lava lamp bubble, until it reaches the crust. If it's hot enough, the magma can melt it's way through to the surface, causing those things we call volcanoes to form.
Heat from the earth's interior reaches the surface through a combination of convection and conduction.

highlight factors which show that heat from the sun does reach th earth surface by convection
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.

False.
It's called the convection current.
