Facts About Planet Earth

" Those who contemplate the beauty of the Earth find reserves of strength that will endure as long as life lasts. "

- Rachel Carson

The rocks you are standing on get recycled. Volcanoes spit them out as magma, they dry, harden, and after a very long time either get sucked down again by plate tectonics or get pushed towards Earth's core by a fresh layer of rocks above.

Speaking of magma, the hottest temperature ever recorded on Earth's surface was 136 degrees F or 57.8 degrees C in El Azizia, Libya recorded in 1922.

Gravity is not distributed equally. Yes, you read that right. Places like Hudson Bay in Canada actually have less gravity than other regions of the globe. This is due to the fact that there is less land mass in that part of the planet thanks both to retreating glaciers on the surface and swirling magma deep in the core.
