Both of these states are also mountainous states with the same rocky mountain chain running through each of them, so they have very similar geographies.
These vents form along mid-ocean ridges, where Earth's tectonic plates are splitting apart, and lava rises up through the gap, then hardens into long underwater mountain chains.
Undersea Mountains: The Mid--Ocean Ridges Mid--ocean ridges, the longest mountain chains on Earth, are formed at divergent plate boundaries where two oceanic plates move apart.
No other mountain chain on this or any other of the continents that I have seen is so rich as the Sierra in bold, striking, well-preserved glacial monuments.
How have they been distributed from continent to continent, across seas and deserts and mountain chains, usually so influential in determining boundaries of species both of plants and animals.
