That’s taller than a 30-story building! They are also very old. Some redwood trees are more than 2,000 years old.
Redwood trees are very strong. Their trunks are thick and can be up to 7 meters in diameter. Even after a big storm, many redwood trees still stand. Why are they so strong Because their wood is hard and they have deep roots that connect with other redwood roots. This helps them stay stable.
Redwood trees are also important for the ecosystem. Many animals live in redwood forests, such as birds, squirrels and deer. The trees provide them with food and homes. Redwood trees also help clean the air and water.

The cheetah is known as the fastest land animal in the world. It can run at a speed of up to 112 kilometers per hour. That’s faster than a car on a city road! But cheetahs can’t keep this speed for a long time. They usually run fast for only 20 to 30 seconds.
Cheetahs have many features that help them run fast. They have long legs and a thin body. Their claws are sharp and can grip the ground well. Their tail helps them keep balance when running.
Cheetahs live in Africa, mainly in grasslands and savannas. They hunt small animals like rabbits and gazelles. They use their speed to catch their prey. After catching prey, cheetahs need to rest because running fast uses a lot of energy.
Sadly, cheetahs are an endangered animal. The number of cheetahs is getting smaller because their homes are being destroyed and they have less food to eat. People are trying to protect cheetahs by setting up protected areas for them.
