The Great Rift Valley, pictured above from a tourist stop in Kenya, is a trench that runs from Lebanon to Mozambique, and is the location where two tectonic plates in the earth’s crust push each other aside: the Somali and the Nubian plates.

There are, of course, other locations on earth where such plates intersect.

In the Netherlands, for example, where they already fight sinking soil levels due to the centuries of pumping out subterranean water, they face the additional dilemma of having their coastline situated along a tectonic fault or rift, which moves their region incrementally lower, and their neighbors across the channel–Norway and Sweden, incrementally higher.

So, within the same small region in Northern Europe, sea levels are both rising and falling at the same time–it just depends on what side of the tectonic fault the data is being collected from. Here’s a map that shows fault-lines around the globe.

In North America, geologists studying paths of ancient glaciers “discovered other layers of similar soil from earlier times—a sign that the climate had not changed just once, but at least three or four times.”

The Western Interior Seaway is the name of an ancient ocean that bisected North America in the geologic past. It covered much of the central U.S., and it left behind seashells on mountaintops all over the nation.

Eastern Washington State in the U.S. is a desert that shows evidence of massive floodwaters radically affecting the landscape in aeons past.
