-Using the geologic laws of relative dating, list the labeled rock layers and events (like faults and erosion surfaces) in order from the oldest to the youngest. -How can you tell if A is older or younger than N?

-How can you tell if H is older or younger than M?

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.
