These photos might look like they come from an alien planet, but it turns out our own little Earth is capable of some truly weird stuff. All of these things occur naturally across the globe. A lot of the reasons why go over my head, but it's all true. It's easy to appreciate the wondrous beauty of Earth without knowing exactly how it happens. Take a look at some of the cool things you didn't realize happen on our home planet. #1. Never-ending Wave: Occurs twice a year in Brazil when the Atlantic ocean meets the mouth of the Amazon River. The resulting waves can travel 500 miles inland before slowing down. #2. Danxia Landforms: Over millions of years, the red sandstone and mineral deposits in certain areas of China have created these rainbow-like landforms. #3. Horsetail Falls: In Yosemite National Park, California, this waterfall looks more like lava with a bright orange glow at certain times of the day in February. #4. Assembly Of Crabs: Off the coast of Australia on Christmas Island, the annual migration of nearly 120 million red crabs creates quite a sight as they make their way to the ocean. #5. Lake Abraham, Canada: This human-made and committee-named lake is known by nature photographers everywhere for the way its bubbles freeze mid-rise in the water during the winter. Of course, the bubbles aren't air, but methane gas, caused by bacteria eating dead organic matter on the lake floor. That means that this lake gives off flammable gas.
