Oceanic crust is continuously created at mid-ocean ridges through a process known as seafloor spreading. This process occurs when two tectonic plates move away from each other, creating a rift in the ocean floor. As the plates move apart, molten rock from the Earth’s mantle rises up and fills the gap. This molten rock cools […]
An apparent polar-wander path for a continent is a record of the continent’s changing orientation relative to the Earth’s north and south magnetic poles over a period of time. It is typically represented as a curve on a map that shows the continent’s longitude and latitude relative to the poles. The curve reflects changes in […]
