The Earth's Dynamic Crust

You are literally surfing on molten rock right now. Even though the ground feels solid,

the Earth’s crust is actually broken into massive plates floating on hot, semi-melted goo

called the asthenosphere. It is basically a giant, slow-motion car crash where continents

smash together to build mountains or rip apart to create oceans. When these plates

get stuck, pressure builds up until they snap, causing earthquakes, or magma punches

through to make volcanoes. Eventually, all that rock grinds down into soil,

which is the only reason we can grow food. The planet is constantly recycling itself

beneath your feet.
