This 'shield' is called an atmosphere, and it is there to hold all the elements humans require to survive such as oxygen, hydrogen and the other molecules in the air.

Why does the earth get hot?

-If you mean the surface, it's because of the sun. It partially has to do with pollution (global warming). There's like a shield around the Earth. The "shield" protects living things from some of the sun's heat. With too much CO2 in the air, the shield is weakening. -If you mean the seasons, it's because of the Earth's tilt on its axis. The part closer to the sun is hotter (frankly, the equator). -If you mean the inside of the Earth, it's because of geothermal energy. Heat comes from the Earth too!
