Bedrock lies beneath the surface materials such as soil, gravel, sand and other sediments. It is a deposit of hard, consolidated, tightly-bound solid rock. It is the parent material for unconsolidated material and soil above thus influencing landscapes.

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.
