Where is new crust formed and where does old crust go?

A mid-ocean ridge causes the magma to come out of the rift, when it comes out the next stage is it becomes cold and hard which forms new oceanic crust. The new crusts keep pushing the old ones into subduction zones into a trench.

temperatures get warmer — and heatwaves are more common. nothing says summer like warm weather. this rise in temperatures is caused by the tilt of the earth's axis. our planet doesn't sit perfectly straight as it spins — it has a slight lean of approximately 23.5 degrees with respect to the sun, called the axial tilt.
