Glacier

A glacier is like a really big ice cube, but it's not in your drink, it's outside, on mountains, and it's HUGE! It's so big that it looks like a huge river of ice that moves very, very slowly. Like, if you could run faster than a glacier moves, you'd be super fast!

Glaciers happen when it's really, really cold, so that snow doesn't melt. After snow falls on a mountain, it gets compressed and squeezed down by more snow on top of it, until it becomes ice. As more snow keeps falling, the ice becomes bigger and bigger, until it's huge enough that it starts to move.

Glaciers move like turtles, but not quite as fast. They can move as slow as a few centimeters per day, which is like the speed of a snail, which is super slow! They move because the weight of the ice pushes it down and forward, and gravity pulls it down the mountain.

Glaciers are very important because they store a lot of water. When the weather gets warmer or when the sun comes out, the glacier melts, and the water flows down the mountain, forming rivers and lakes. People and animals drink this water, and plants use it to grow.

So, glaciers are like giant ice cubes on the mountains that store water and move super slow like turtles, and when they melt, they make water that we can drink and use for the plants and animals.
