Every second of every hour of every day.
This is true. The greenhouse effect on earth holds back heat escaping from the earth.
lithosphere
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.
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
They stop heat from escaping the atmosphere.
Convection currents are agents of heat transfer within Earth's interior. And could also serve as mechnism for heat generation in the earth crust.
Heat from the earth's interior reaches the surface through a combination of convection and conduction.
