"Europe's most significant geological feature is the dichotomy between the highlands and mountains of Southern Europe and a vast, partially underwater, northern plain ranging from Great Britain in the west to the Ural Mountains in the east."

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
