Here grow the tallest trees on Earth. They are called coast redwoods. Some are as tall as a 35-story building! Redwoods are truly amazing. The tallest one, named Hyperion, stands at 115.9 meters. That's taller than the Statue of Liberty! These giants can live for more than 2,000 years. Some were already old when the Roman Empire began. How do redwoods grow so tall? They have a special system for getting water. Their roots spread wide, not deep. This helps them take water from the ground. The fog that rolls in from the ocean also gives them water. The leaves take in water directly from the fog! Redwoods have very thick bark, up to 30 centimeters. This protects them from fire and insects. Their wood contains a chemical that keeps bugs away. That's why redwood trees can live so long. These forests are home to many animals. Banana slugs, black bears, and spotted owls all live among the giants. The forest floor is soft with ferns and moss. Today, redwood forests are protected. People can visit and walk among these ancient giants. Standing next to a 2,000-year-old tree makes you feel very small. It's a humbling experience that reminds us to protect nature's wonders. Comprehension Questions 1. How tall can redwood trees grow?

This amazing sight is called the Northern Lights, or Aurora Borealis. It is one of nature's most beautiful shows. The Northern Lights happen near the North Pole. People in countries like Norway, Sweden, Finland, Canada, and Alaska can see them. The best time to watch is on cold, clear winter nights from September to March. What causes these beautiful lights? It starts with the sun. The sun sends out tiny particles all the time. When these particles reach Earth, they hit gases in our air. This collision creates light. Different gases make different colors. Oxygen gives us green and red light. Nitrogen gives us blue and purple light. The Northern Lights have fascinated people for thousands of years. Some ancient people thought they were spirits dancing in the sky. Others believed they were messages from the gods. Today, we know the science behind them, but they are still magical to see. Many people travel to the Arctic just to see this wonder. Some wait for hours in the cold, hoping the lights will appear. When the sky lights up with dancing colors, they say it's worth every minute. If you ever get a chance to see the Northern Lights, don't miss it. It's a reminder of how amazing our planet really is. Comprehension Questions 1. Where can people see the Northern Lights?

It's the Great Barrier Reef. This is the largest coral reef system in the world. It stretches for 2,300 kilometers along Australia's east coast. The reef is not just one thing. It is made of billions of tiny animals called coral polyps. These small creatures build hard skeletons around themselves. Over thousands of years, millions of these skeletons piled up to form the reef. The Great Barrier Reef is home to an amazing variety of life. More than 1,500 species of fish live there. You can find clownfish, parrotfish, and giant groupers. Sea turtles, dolphins, and sharks also call the reef home. There are also 400 types of coral and thousands of other sea creatures. The colors of the reef are breathtaking. Bright blue water, pink and purple coral, and fish of every color create an underwater rainbow. This is why so many divers come from around the world to see it. But the reef is in danger. Climate change is making the ocean warmer. This causes coral bleaching, which kills the coral. Pollution and overfishing also harm the reef. Scientists say we need to act fast to save this wonder. You can help too!
