1. What is the fastest land animal in the world?
Answer: Cheetah
The cheetah can reach speeds of up to 75 miles per hour (120 km/h) in short bursts covering distances up to 1,500 feet. However, it can only maintain this speed for about 20-30 seconds. Cheetahs are built for speed with lightweight bodies, long legs, and flexible spines that allow them to cover 20-25 feet in a single stride!
2. Which animal has the longest lifespan?
Answer: Greenland Shark
The Greenland shark can live for over 400 years, making it the longest-living vertebrate on Earth. Scientists discovered a 392-year-old Greenland shark in 2016! These slow-moving creatures live in the cold waters of the North Atlantic and grow only about 1 cm per year.
3. What percentage of Earth's surface is covered by water?
Answer: Approximately 71%
About 71% of Earth's surface is covered by water, with oceans holding about 96.5% of all Earth's water. The remaining water exists as ice, groundwater, lakes, rivers, and in the atmosphere. Despite this, less than 1% of Earth's water is fresh and accessible for human use.
4. Which tree is known as the "Tree of Life"?
Answer: Baobab Tree
The baobab tree, native to Africa, Madagascar, and Australia, is often called the "Tree of Life" because it provides food, water, shelter, and medicine. These massive trees can live for over 1,000 years and store up to 32,000 gallons of water in their trunks during the rainy season!
5. What is the largest living organism on Earth?
Answer: Armillaria ostoyae (Honey Fungus)
While blue whales are the largest animals, the largest living organism is a honey fungus in Oregon's Malheur National Forest. This fungus covers 2,385 acres (about 1,665 football fields) and is estimated to be between 2,400 and 8,650 years old! It's all one connected organism underground.
6. Which bird can fly backwards?
Answer: Hummingbird
Hummingbirds are the only birds that can fly backwards, upside down, and hover in place. Their wings beat 50-200 times per second, creating a humming sound (hence their name). They can also fly at speeds up to 60 miles per hour and migrate thousands of miles despite weighing less than a nickel!
7. What is the deepest point in the ocean?
Answer: Mariana Trench (Challenger Deep)
The Mariana Trench in the Pacific Ocean reaches a depth of about 36,070 feet (10,994 meters) at Challenger Deep. That's deeper than Mount Everest is tall! The pressure at this depth is over 1,000 times greater than at sea level. Only a few humans have ever visited this extreme environment.
8. Which animal has the strongest bite force?
Answer: Saltwater Crocodile
The saltwater crocodile has the strongest bite force of any living animal, measuring up to 3,700 pounds per square inch (psi). That's more than 15 times stronger than a human bite! These massive reptiles can grow up to 23 feet long and weigh over 2,000 pounds.
9. What causes the Northern Lights (Aurora Borealis)?
Answer: Solar particles colliding with Earth's atmosphere
The Northern Lights occur when charged particles from the sun (solar wind) collide with gases in Earth's atmosphere, particularly oxygen and nitrogen. These collisions create beautiful displays of light in the sky. The colors vary: green and yellow come from oxygen, while red and blue come from nitrogen.
10. Which plant is known as the "corpse flower" and why?
Answer: Amorphophallus titanum
The corpse flower (Amorphophallus titanum) gets its name because it smells like rotting flesh when it blooms. This rare plant, native to Sumatra, can grow up to 10 feet tall and blooms only once every 7-10 years. The smell attracts carrion beetles and flesh flies that help pollinate it!
