  • It's a drizzly, rainy day outside.

  • So we thought we'd pull out a few of our books and explore some cool, colorful places

  • where wet weather is pretty much the only weather there is.

  • I'm talking about rainforests!

  • You can probably tell from the name that rainforests have a whole lot of two things: trees and rain.

  • And sure enough, rainforests get more rain than any other place on Earth.

  • In some areas of the rainforest, it rains every day!

  • And people often think that rainforests all look like this:

  • warm and steamy with animals like colorful birds

  • and plants like bananas and mango trees.

  • And there are lots of rainforests like that.

  • But a rainforest can also look like this.

  • Home to animals that are adapted to cooler weather, like bears and elk.

  • Both of these places are rainforests, but they're found in different parts of the world.

  • The warm rainforests are found here,

  • close to the imaginary line that runs around the middle of the Earth.

  • This part of the world is calledThe Tropics”,

  • it gets lots of sun which is why the temperature is really warm almost all the time.

  • And there are a lot of different kinds of plants and animals

  • that live in these warm rainforests!

  • So many, in fact, that scientists talk about the rainforest as having layers

  • that change as you go from the top to the bottom.

  • And different animals and plants live in each layer.

  • For example, at the top layers of the rainforest in the tropics,

  • all you can see is the very tippy-tops of the tallest trees.

  • There's lots of sunlight up there that the trees use to grow,

  • so these tall trees have lots of leaves.

  • And these big, leafy trees make lots of shade!

  • They block some of the sunlight from getting to the lower layers,

  • kind of like a big, green umbrella.

  • And all of the leaves and fruit in the top layers

  • means that there's plenty of food for animals to eat.

  • So many different kinds of animals live up here,

  • like insects, parrots, bats, monkeys, and sloths!

  • Some of these animals never even go down to the ground at all;

  • they don't need to!

  • Everything they need is at the top of the rainforest.

  • Now, the lower layers don't get as much sunlight as the top,

  • but there's still home to plenty of living things,

  • like snakes, lizards, and even big cats, like tigers and jaguars.

  • And just like the animals at the top of the rainforest,

  • animals down below are perfectly suited to the place where they live.

  • The big cats, for example, have patterns on their coats

  • that help them blend in with the rainforest.

  • The jaguar has spots, and the tiger, as you all know, has stripes.

  • And these patterns help the animals hide amongst the shadows of the trees.

  • Okay, but what about the cooler rainforests?

  • They're found here, much farther away from the tropics.

  • These rainforests are cooler

  • because they don't get as much sun as the warmer ones.

  • They also have layers, but the plants and animals that live there are pretty different!

  • The top layer of the cooler rainforest, for example, is made of conifers.

  • Those are the kinds of trees that usually have cones, like pines and redwood trees.

  • And these kinds of trees have needles too, like some other kinds of evergreens.

  • These needles help the trees save energy during the cold winters.

  • And it's not only the plants that are different here!

  • Animals that live in these rainforests

  • also have to be able to live in cooler temperatures.

  • So many of the creatures that live in the lower layers of these rainforests

  • have coats that help keep them warm.

  • For example, some tigers live in these cool rainforests,

  • and they also have striped coats that help them blend into the shadows.

  • But their fur is nice and thick, so it keeps them warm!

  • And other furry mammals live in these cold forests,

  • like brown bears, black bears, and elk.

  • Quite different from the macaws and monkeys that live in the warmer forests!

  • Wow, that was quite an imaginary tour!

  • We went all over the world in just a few minutes!

  • But now I want to find out even more

  • about the amazing rainforests around our world!

  • Come on Squeaks, let's head to the library!

  • Thanks for joining us on SciShow Kids!

  • Do you have a question about something,

  • or someplace in the world that you'd like to learn more about?

  • If so, ask a grown-up to help you leave a comment down below,

  • or send us an email to kids@scishow.com

  • Thanks, and we'll see you next time here at the fort!

It's a drizzly, rainy day outside.
