Every spring, hundreds of adventurers set their sights on climbing Mount Everest, also known as Qomolangma. At the base camp, they spend months preparing for the chance to reach the mountain’s towering peak. But what makes people take such risks to climb Everest? Is it the challenge, the breathtaking view, or the thrill of being so high up? For many, it’s because Everest is the highest mountain on Earth.
While Mauna Kea is technically the tallest mountain from base to summit, Mount Everest holds the record for the highest altitude, standing at 8,850 meters above sea level. To understand how Everest got so tall, we need to explore deep beneath the Earth’s surface, where giant pieces of the Earth’s crust, called continental plates, collide. Imagine the Earth’s surface like a jigsaw puzzle with pieces that are always moving. These plates shift about two to four centimeters each year, which is roughly the speed at which your fingernails grow.
When two plates crash into each other, one might slide under the other, causing the edges to crumple and rise. This is how Mount Everest was born. Around 50 million years ago, the Indian Plate moved north and collided with the larger Eurasian Plate. This collision caused the land to crumple and rise, forming the mighty Everest right in the middle of this collision zone.
Mountains aren’t just shaped by the uplifting of land. As the land rises, the air above it also rises, cools down, and causes water vapor to turn into rain or snow. This precipitation erodes the landscape, breaking down rocks in a process called weathering. Water flowing downhill carries away the weathered material, carving out deep valleys and sharp peaks. The balance between uplift and erosion determines a mountain’s shape.
Not all mountains are the same. When plates first collide, mountains rise quickly, forming tall peaks with steep slopes. Over time, gravity and water wear them down. Eventually, erosion can outpace uplift, wearing down the peaks faster than they rise.
Climate also plays a big role in shaping mountains. In very cold places, some snow doesn’t melt and instead turns into ice, forming a snowline. This snowline varies around the world depending on the climate. At the freezing poles, the snowline is at sea level, but near the equator, you have to climb five kilometers before it gets cold enough for ice to form.
Ice that gathers begins to flow under its own weight, creating a slow-moving frozen river called a glacier. Glaciers grind the rocks below them. The steeper the mountain, the faster the glacier flows, carving the rock beneath it. Glaciers can erode landscapes faster than rain and rivers. Where glaciers cling to mountain peaks, they can quickly wear them down, flattening the tops.
So, why is icy Mount Everest still so tall? The massive collision that formed it made it huge from the start. Plus, because Everest is near the tropics, the snowline is high, and the glaciers are small, not big enough to erode it significantly. Everest exists in a unique set of conditions that help it maintain its impressive height.
However, this might not always be the case. Our world is constantly changing, and one day, the movement of continental plates, changes in climate, and erosion might work together to reduce Everest’s height. For now, it remains a legendary peak in the minds of hikers, adventurers, and dreamers everywhere.
Imagine you’re a scientist studying the Earth’s crust. Use clay or playdough to create models of the Indian and Eurasian plates. Slowly push them together to simulate the collision that formed Mount Everest. Observe how the clay crumples and rises, mimicking the mountain-building process. Discuss with your classmates how this activity helps you understand the formation of Everest.
Conduct an experiment to see how weathering and erosion shape mountains. Use sugar cubes to build a small mountain and then simulate rain using a spray bottle. Observe how the water breaks down the sugar cubes, representing weathering and erosion. Reflect on how this process affects real mountains like Everest over millions of years.
Research different climates around the world and how they affect the snowline on mountains. Create a poster showing the snowline at various latitudes, from the poles to the equator. Explain why the snowline is higher near the equator and how this impacts glaciers on mountains like Everest.
Use a block of ice to represent a glacier and place it on a sloped surface covered with sand or small pebbles. Gently push the ice block to simulate glacier movement. Observe how the ice grinds the surface beneath it. Discuss how glaciers shape mountains and why Everest’s glaciers are less effective at eroding it.
Engage in a debate about the future of Mount Everest. Consider factors like plate tectonics, climate change, and erosion. Predict how these forces might alter Everest’s height in the future. Share your thoughts on whether Everest will remain the tallest mountain and what changes might occur over time.

Every spring, hundreds of adventure-seekers dream of climbing Qomolangma, also known as Mount Everest. At base camp, they prepare for months, waiting for the chance to scale the mountain’s lofty peak. But why do people risk so much to climb Everest? Is it the challenge, the view, or the chance to touch the sky? For many, the draw is Everest’s status as the highest mountain on Earth.
It’s important to note that while Mauna Kea is actually the tallest mountain from base to summit, Everest, at 8,850 meters above sea level, has the highest altitude on the planet. To understand how this towering formation was created, we need to look deep into the Earth’s crust, where continental plates collide. The Earth’s surface is like an armadillo’s armor, with pieces of crust constantly moving over, under, and around each other. For such large continental plates, the motion is relatively quick, moving two to four centimeters per year, about as fast as fingernails grow.
When two plates collide, one pushes into or underneath the other, buckling at the edges and causing uplift to accommodate the extra crust. This is how Everest was formed. About 50 million years ago, the Indian Plate drifted north and collided with the larger Eurasian Plate, causing the crust to crumple and create significant uplift. Mount Everest lies at the heart of this collision zone.
Mountains are shaped by forces other than uplift. As land is pushed up, air masses are forced to rise as well. Rising air cools, causing any water vapor within it to condense and form rain or snow. As that precipitation falls, it erodes the landscape, breaking down rocks in a process known as weathering. Water moving downhill carries the weathered material, carving out deep valleys and jagged peaks. The balance between uplift and erosion gives a mountain its shape.
However, not all mountains are alike. When continental plates first collide, uplift occurs rapidly, creating tall peaks with steep slopes. Over time, gravity and water wear them down, and eventually, erosion can outpace uplift, wearing down peaks faster than they are pushed up.
Climate is another factor that shapes mountains. In subzero temperatures, some snowfall doesn’t completely melt away and instead slowly compacts into ice, forming the snowline, which occurs at different heights around the planet depending on climate. At the freezing poles, the snowline is at sea level, while near the equator, you have to climb five kilometers before it gets cold enough for ice to form.
Gathered ice begins to flow under its own immense weight, forming a slow-moving frozen river known as a glacier, which grinds the rocks below. The steeper the mountains, the faster the ice flows, and the quicker it carves the underlying rock. Glaciers can erode landscapes more rapidly than rain and rivers. Where glaciers cling to mountain peaks, they can sand them down quickly, effectively flattening the tops.
So, how did the icy Mount Everest become so tall? The cataclysmic continental collision that formed it made it massive to begin with. Additionally, the mountain’s location near the tropics means the snowline is high, and the glaciers are relatively small, not large enough to significantly erode it. The mountain exists in a unique set of conditions that maintain its impressive stature.
However, this may not always be the case. We live in a changing world where continental plates, Earth’s climate, and erosive forces might one day work together to reduce Mount Everest’s height. For now, it remains legendary in the minds of hikers, adventurers, and dreamers alike.
