A Guide to the Energy of the Earth

Energy moves in and out of Earth’s physical systems, and during any energy transfer between them, some energy is lost to the surroundings as heat, light, sound, vibration, or movement.

Our planet’s energy comes from internal and external sources. Geothermal energy from radioactive isotopes and rotational energy from the spinning of the Earth are internal sources of energy, while the Sun is the major external source, driving certain systems, like our weather and our climate.

Sunlight warms the surface and atmosphere in varying amounts, and this causes convection, producing winds and influencing ocean currents. Infrared radiation, radiating out from the warmed surface of the Earth, gets trapped by greenhouse gases and further affects the energy flow.

Will: Carlton, carlton, I understand that you’re scared, man, but the world can be a scary place. Just got to learn to deal with it.

Carlton: Yeah, well, I found my way.

Will: That’s not you, man. that’s them.

^ i remember this episode i cried while watching this 

Me too. 😢

This episode had me in tears, man. Like, you really knew the characters were growing from this. I loved how it was comedy and still touched on issues that affected Black youth. We need more shows like this on television.

You gotta think, the whole concept of this show was Will growing up in a bad neighborhood where shit like this happened all the time, and Carlton grew up in a life of privilege and sheltered from this kind of life, and I think Will was crying because he came so close to seeing Carlton go down the wrong path and end up like some of his friends back in Philly.

This show is so important.
