What Is a Rainforest, and Where in the World Are Rainforests Found?
A rainforest is a thick, green forest that gets a great deal of rain, usually more than 80 inches a year! Most are tropical, growing in a warm belt around the middle of the Earth. They cover a small slice of the land, but hold a huge number of living things.

How Is a Tropical Rainforest Different From a Temperate Rainforest?
A tropical rainforest is hot and wet all year, near the equator. A temperate rainforest is cooler, and grows near the ocean where rain and fog roll in. Both are rainy forests, but they have very different trees and animals!
Watch on YouTube
Why Do Tropical Rainforests Grow in a Belt Around the Middle of the Earth?
Near the equator, the Sun shines almost straight down all year long. That keeps the land and sea warm, and warm air makes lots of rain. With warmth, rain, and sunlight, plants can grow nonstop, so a green belt of rainforest circles the Earth!

What Are the Four Layers of a Rainforest?
A rainforest has four layers, like floors in a tall building. From top to bottom they are the emergent layer, the canopy, the understory, and the forest floor. Each layer has its own light, temperature, and animals, so each is a different world.
Watch on YouTube
Why Do a Few Rainforest Trees Poke Up Above All the Others?
Trees in the emergent layer stretch up 150 feet or more, which is 45 meters, to catch the brightest sunlight. They also catch the breeze that carries their pollen and seeds. A gap in the canopy gives them a chance to grow toward the light.
Watch on YouTube
Why Is the Canopy Called the Roof of the Forest?
The canopy is the thick layer where the branches and leaves of most tall trees meet. It is about 60 to 100 feet up, which is 18 to 30 meters. It catches most of the sunlight and rain, so it shelters the layers below, like a roof.
Watch on YouTube
What Is the Understory, and Why Is It So Still and Shady?
The understory is the layer under the canopy where young trees, shrubs, and ferns grow. Only a small amount of sunlight filters down, and the canopy blocks the wind. That makes the air calm, humid, and shady.
Watch on YouTube
Why Is the Rainforest Floor So Dark?
The thick canopy and understory catch most of the sunlight before it reaches the ground. In some rainforests, only about 2 percent of the light makes it to the floor. That is why the forest floor is so dark.
Watch on YouTube
Why Are So Many Rainforest Trees Tall and Skinny with No Branches Near the Ground?
Rainforest trees race one another for sunlight. A tall trunk with no low branches grows fast toward the light. It saves energy by not growing leaves where it is dark, and spreads its branches only at the top.
Watch on YouTube
How Tall Can a Rainforest Tree Grow?
Some tropical trees grow more than 200 feet tall, which is 60 meters and taller than a 20-story building. In Borneo, scientists have measured trees almost 330 feet tall. Growing so high helps them win the race for sunlight.
Watch on YouTube
Why Does the Air Under the Trees Feel Like a Warm, Wet Blanket?
Trees release water vapor from their leaves, and the thick canopy traps that moisture and keeps the wind out. So the air near the ground can be nearly 100 percent humid. It feels like a warm, wet blanket!
Watch on YouTube
Why Does the Temperature Stay Almost the Same All Year in a Rainforest?
Near the equator, the Sun's strength barely changes through the year, so every month is warm. Clouds and the thick canopy also keep days from getting scorching and nights from getting cold. That is why the temperature stays almost the same.
Watch on YouTube
How Many Kinds of Living Things Live in a Rainforest?
Rainforests hold more kinds of plants and animals than any other land habitat. They cover only about 6 percent of Earth's land, yet by many estimates they are home to more than half of all land species. Scientists think millions of them are still unnamed!
Watch on YouTube
Why Can a Small Patch of Rainforest Hold Hundreds of Kinds of Trees?
In many forests, a few kinds of trees dominate. In a rainforest, each kind of tree is rare, so a small patch may have hundreds of different trees with only a few of each. Scientists think pests and diseases help make this happen.
Watch on YouTube
Why Is a Rainforest So Loud?
A rainforest is packed with animals that call, buzz, and chirp. Frogs sing, insects click and hum, birds shout, and monkeys howl. Together they make a huge, noisy choir!
Watch on YouTube
Why Does the Rainforest Smell Earthy and a Little Sweet?
The rainforest smell comes from busy recycling. Fallen leaves, wood, and fruit are broken down by fungi and bacteria, which release smelly gases. Flowers and fruit add sweet smells to the mix.
Watch on YouTube
Are Rainforests Really the Lungs of the Earth?
You may have heard that rainforests are the lungs of the Earth, but that saying is mostly a myth. Rainforest plants do make lots of oxygen, but the forest's animals, fungi, and bacteria use up almost as much. Still, rainforests are hugely important!
Watch on YouTube
Why Are There So Many Insects in Rainforests?
Warm, wet weather all year means insects never have to sleep through a winter. There are plenty of leaves, flowers, wood, and fruit to eat, plus countless hiding places. That is why rainforests are packed with insects!
Watch on YouTube
How Do So Many Animals Share One Rainforest Without Crowding Each Other Out?
Each kind of animal has its own job, food, and place to live. Scientists call this a niche. One bird eats fruit in the canopy while another snaps up insects on the forest floor.

What Is a Cloud Forest?
A cloud forest grows high on a tropical mountain, where clouds drift right through the trees. The air is cool, damp, and misty all day long. The trees are covered with moss, ferns, and orchids that soak up water from the fog.
Watch on YouTube
What Lives in a Temperate Rainforest on the Pacific Coast?
The Pacific coast has huge trees like western red cedar, Sitka spruce, and western hemlock, along with ferns and thick moss. Black bears, wolves, bald eagles, and salmon live there too. Winds from the ocean push wet air against the mountains, so it rains a lot.
Watch on YouTube
Why Are Temperate Rainforests Covered in Moss?
Moss loves damp, cool, shady places, and temperate rainforests have plenty of all three. Moss has no roots to take up water, so it soaks it up straight from the air and rain. It can cover branches, logs, and rocks in a thick green carpet.
Watch on YouTube
Why Do Some Rainforests Flood for Part of the Year?
In the Amazon basin, heavy rains and melting snow far away make rivers rise as much as 30 or 40 feet for months. The water spreads into the forest, creating a flooded forest. Trees there are adapted to this yearly flood cycle.

What Happens to a Raindrop on Its Way Down Through the Forest?
A raindrop hits the canopy first. Some drops cling to leaves and evaporate straight back into the air, while others drip from leaf to leaf or run down branches and trunks. So a raindrop's trip through the forest can be long and slow!
Watch on YouTube
Why Does It Rain Almost Every Afternoon in Some Rainforests?
In some rainforests, it rains almost every afternoon like clockwork! In the morning, the Sun heats the forest and water evaporates into the air. By afternoon, that warm, wet air has built into tall clouds that release heavy showers.
Watch on YouTube
How Does a Rainforest Help Make Its Own Rain?
Trees pull water from the soil and release it as vapor through tiny pores in their leaves. This is called transpiration. Millions of trees add huge amounts of moisture to the air.
Watch on YouTube
What Are the Flying Rivers of the Amazon?
Flying rivers are streams of water vapor that flow through the air above the rainforest, carried by winds. They bring moisture from the Atlantic Ocean across the forest, and the trees add more along the way. The vapor eventually turns into rain far from where it started.
Watch on YouTube
Why Does Mist Rise From the Forest After a Storm?
After a storm, the leaves, branches, and ground are warm and wet. When the Sun comes out, water evaporates into the cooler air above. The vapor turns into tiny droplets you can see as mist, and it looks like the forest is breathing!
Watch on YouTube
Why Is Rainforest Soil Poor Even Though Plants Grow So Thickly?
Rainforest soils are old, and heavy rain keeps washing the nutrients down and away. Most nutrients are locked inside living plants and fresh leaf litter. So the forest feeds itself in a fast loop rather than from a rich soil bank.
Watch on YouTube
How Can Giant Trees Grow in Poor Soil?
Most rainforest trees have shallow, wide roots that spread through the top few inches of soil. That is where fallen leaves rot and release nutrients. Helpful fungi on the roots help them take in minerals and water.
Watch on YouTube
Why Does a Fallen Leaf Disappear in Just a Few Weeks?
In the warm, wet air of the rainforest, decomposers work very quickly. Fungi, bacteria, termites, and other tiny animals break down dead leaves into simple nutrients that plants can use again. In a cooler forest, a leaf might last a year or more, but in a rainforest it can be gone in weeks!
Watch on YouTube
Why Do Mushrooms and Other Fungi Love the Forest Floor?
Fungi are the forest's recyclers. They grow long, thread-like strands through dead leaves and wood, digesting them from the outside. What you see as a mushroom is only the fruiting part that releases spores.

What Happens When a Giant Tree Falls in a Rainforest?
A falling tree can drag down vines and smaller trees, opening a gap in the canopy. Sunlight pours in, and seedlings that had been waiting in the shade race upward. Within a few years, the gap fills with new green growth.
Watch on YouTube
Why Do Tiny Seedlings Wait in the Shade for Years?
Seedlings that start in the dark can't grow much, so they stay small and grow very slowly. Sometimes they wait for decades, saving their energy. When a tree falls and opens a gap, light reaches them and they shoot upward.
Watch on YouTube
Why Can a Tropical Sapling Shoot Up So Quickly?
Plants need sunlight, water, and warmth, and a rainforest has all three nearly all year. There is no winter to stop growth, so plants can keep making leaves, wood, and fruit. Some saplings shoot up more than ten feet in a year!
