Check out that bright blue water!
Why are some mountain lakes so beautiful? Thank a glacier.

It was one of the Earth's momentous times. Continents collided. Volcanoes erupted. Ocean currents shifted. Species ran amok.
Old Faithful erupts periodically because of an unchanging natural process of water boiling underground
Geysers spout up where a column of underground water is heated to boiling by "magma," or molten rock, pushing the water upward.
Antarctica is actually home to a multiple active volcanoes, including Mt. Erebus.
According to geologists, there's something very hot going on under all that ice.
Even oxygen-breathing animals as ancient as trilobite didn't come around until long after Earth's atmosphere had become oxygen-rich.
Most of us take our oxygen-rich atmosphere for granted. Once upon a time, though, Earth's air was very different.
Earthquakes follow fracking sites around the country.
Scientists link fracking to the surge in earthquakes across the U.S.
