25 interesting facts about the Earth:<br /><br />1. Earth is the third planet from the Sun, and it is the only known planet to support life.<br />2. It has a diameter of about 12,742 kilometers (7,918 miles).<br />3. Earth is approximately 4.5 billion years old.<br />4. The planet's surface is about 70% water, earning it the nickname "the Blue Planet."<br />5. The Earth's atmosphere is composed primarily of nitrogen (78%) and oxygen (21%).<br />6. The highest point on Earth is Mount Everest, which reaches 8,848 meters (29,029 feet) above sea level.<br />7. The lowest point on land is the Challenger Deep in the Mariana Trench, which plunges about 10,994 meters (36,070 feet) below sea level.<br />8. Earth orbits the Sun at an average distance of about 150 million kilometers (93 million miles).<br />9. It takes Earth approximately 365.25 days to orbit the Sun, creating one year.<br />10. The Earth's rotation on its axis takes about 24 hours, creating one day.<br />11. The Earth's magnetic field is generated by the motion of molten iron in its outer core.<br />12. Earth experiences seasons due to its axial tilt of approximately 23.5 degrees as it orbits the Sun.<br />13. The planet's rotation is gradually slowing down at a rate of about 17 milliseconds per century.<br />14. Earth is the densest planet in the Solar System.<br />15. The Moon is Earth's only natural satellite, and its gravitational pull causes tides.<br />16. The Earth's core is composed mainly of iron and nickel.<br />17. Earthquakes are caused by the movement of tectonic plates beneath the planet's surface.<br />18. The Earth's atmosphere protects life on the planet by blocking harmful solar radiation.<br />19. The ozone layer, located in the stratosphere, helps absorb harmful ultraviolet radiation from the Sun.<br />20. Earth's continents are in constant motion due to plate tectonics, which has shaped the planet's landforms over millions of years.<br />21. The deepest artificial hole ever drilled on Earth is the Kola Superdeep Borehole in Russia, reaching a depth of about 12,262 meters (40,230 feet).<br />22. Earth's oldest known rocks are approximately 4 billion years old, found in Western Greenland.<br />23. The Earth's rotation causes the equatorial bulge, making the planet slightly flattened at the poles and wider at the equator.<br />24. Earth is the only planet in the Solar System known to have active plate tectonics.<br />25. The study of Earth and its processes is known as geology, and those who study it are called geologists.
