Question
In Jules Verne’s 1864 novel, Journey to the Center of the Earth, German Professor Otto Lidenbrock and his team travel to the center of the Earth. They encounter many adventures, including a chamber filled with combustible gas, a subterranean ocean, petrified trees, giant mushrooms, and prehistoric animals.
The fictional story has been popular for over a century. We know, however, that a journey to the center of the Earth would be quite different.
Directions
Your task is to rewrite Journey to the Center of the Earth, imagining that you are in a vehicle that is a giant drill. You can see out of the vehicle’s windows and can drill all the way to the center of the Earth.
Within your story, begin at Earth’s surface and describe the properties of each layer in the order that they are encountered. Include the layers and properties listed in the table below.

### Journey to the Center of the Earth: The Drill Adventure
As I settled into the cockpit of our marvelously constructed giant drill vehicle, affectionately named The Borealis, my excitement bubbled over. This dazzling machine, fitted with advanced technology and equipped for the extreme environments below the Earth’s surface, promised an adventure unlike any other. With a press of the button, the drill roared to life, sending vibrations through my body as the massive drill bits began to spin. We were ready to embark on a journey to the center of the Earth.
#### The Crust
Our adventure began as we broke through the thin layer of the **crust**, which varied in thickness from around 5 kilometers beneath oceans to about 70 kilometers beneath mountain ranges. Through the observation windows, I glimpsed the familiar sight of rocks and soil, made up primarily of silicate minerals. Some chunks of granite and basalt floated past us, reflecting the sunlight filtering through thin fissures. The crust was a jigsaw puzzle of materials that set the stage for everything that lay beneath.
#### The Upper Mantle
As the drill descended deeper, signs of tectonic activity began to make themselves known. We passed through the **upper mantle**, a region defined by viscous rock that flowed slowly due to the immense heat below. Here, the temperature rose dramatically, reaching up to about 1,000 degrees Celsius. I watched in awe as our drill occasionally snagged some peridotite, a dense, rich green rock that was a testament to the immense pressure surrounding us. I contemplated how this layer facilitated plate tectonics, reshaping the Earth's surface over millions of years.
#### The Asthenosphere
Circling into the **asthenosphere**, the drill encountered layers of gooey magma, creating a surreal, glowing ocean as the melted rock pulsed with heat. The motion of the magma was sluggish, and yet it felt like it was alive, convecting slowly beneath us. The temperature surged, and we turned on the cooling systems, which pumped liquid nitrogen to keep the vehicle's internal structures operating at optimal conditions. I could see minerals starting to crystallize from the magma’s surface, twinkling like gems within the undulating soup.
#### The Lower Mantle
Pushing deeper, we entered the **lower mantle**, where immense pressures of up to 1.5 million times the atmospheric pressure existed. The temperature continued to soar, now around 3,500 degrees Celsius. The walls of the drill were lined with heat-resistant material, a necessity in this searing environment. Despite such extremes, I was surprised by the vibrant colors reflecting off the silicate and oxide minerals typical of this bulky layer. Instead of lakes of lava as I had expected, the solid rock resembled a thick, doughy substance, with the occasional tremor reminding me of the forces at play.
#### The Outer Core
As we transitioned into the **outer core**, I felt a disorienting shift. The dense iron-nickel alloy surrounding us finally liquefied into a swirling, molten sea. Remarkably, the liquid outer core was responsible for generating the Earth's magnetic field through the motion of its metallic components. The drill vibrated against the fluid’s surface, and the view outside the window offered a stunning panorama of fiery reds and oranges illuminated by the glowing magma that brewed beneath. It felt like being within a vast cauldron bubbling with ferocity.
#### The Inner Core
Finally, we arrived at the **inner core**. As we broke through the outer shell, a sight unlike any other came into view. The inner core, a solid sphere composed mainly of iron and nickel, radiated a blazing intensity—an incredible 5,700 degrees Celsius. The pressure here was astounding, forcing atoms to crystallize, forming a solid ball that was as dense as lead. The surface shimmered with a metallic glow, and I was struck by how something so incredibly hot could remain solid under pressure surpassing anything I had ever experienced.
With my heart racing and senses overwhelmed, I peered out of The Borealis as it hovered over the shimmering expanse of the inner core. Our journey was remarkable: rich in science, adventure, and the grandeur of our planet's inner workings. I knew that this experience, framed against the rhythmic beats of Earth’s heart, would be etched in my memory forever.
But the world outside, filled with magma chambers and solid metal, left me contemplating the wonders of our geological phenomena and the stories that each layer whispered to those brave enough to listen. With a sense of completion, I turned the drill back toward the surface, ready to share the knowledge gleaned from our extraordinary journey to the center of the Earth.
