Exploring the Depths: The Mysterious Interior of the Earth
Fun Earth Facts Deepest Hole Ever Dug : Humans have only scratched the surface! The deepest hole ever dug is the Kola Superdeep Borehole in Russia, which reached about 12 kilometers (7.5 miles) into the crust—barely making it through the first layer! Dancing Continents : The Earth's crust is broken into massive pieces called tectonic plates, which move around slowly (a few centimeters per year). Over millions of years, continents drift, creating new oceans and mountains. Once upon a time, all the continents were joined together in a supercontinent called Pangaea . Imagine if the Earth still looked like that today! Volcanic Birth : Most volcanoes on Earth are born at the boundaries of tectonic plates. When the plates move, they create cracks in the crust, allowing molten rock from the mantle to escape to the surface—boom! A volcano is born. Magnetic Reversal : Earth's magnetic field has reversed many times in the past, meaning the North and South magnetic poles have switched
