Have you ever seen a waterfall that looks like it's on fire? Or a forest that glows at night? Nature is full of amazing surprises. Let's explore some of them.
The Firefall, USA
In Yosemite National Park, there's a special waterfall called Horsetail Fall. For a few weeks in February, when the sun sets at the right angle, the waterfall turns bright orange. It looks like flowing fire! This happens because the sun's light hits the water at a low angle, making the water look red or orange.
Bioluminescent Beaches, Australia
Some beaches in Australia glow blue at night. Why? Tiny living things called plankton live in the water. When they are touched or moved, they produce light. So if you walk on the beach, the water around your feet will glow. It's like stepping on stars!
The Moving Stones, USA
In Death Valley, there are stones that move on their own. They leave long tracks in the sand, but no one has ever seen them move. Scientists think strong winds and ice might push them. But how? It's still a bit of a mystery.
Nature never stops surprising us. The more we learn about it, the more we realize how wonderful our world is.
