Earth’s Landforms – Mountains

In this lesson, we explored the fascinating world of mountains, a prominent type of landform that rises significantly above its surroundings, typically over 300 meters high. We learned that mountains can form through the collision of tectonic plates or volcanic eruptions, both processes that take millions of years. The lesson encourages further exploration of various landforms and the natural wonders of our planet.
  1. What are some examples of landforms besides mountains that you learned about?
  2. How do you think mountains are different from hills?
  3. Can you explain one way that mountains are formed?

Earth’s Landforms – Mountains

Imagine going on an adventure in nature and looking around at all the different shapes and features of the land. These shapes are called landforms. Some examples of landforms are valleys, hills, canyons, and plateaus.

What Are Mountains?

One type of landform that really stands out is mountains. A mountain is a very high area of land that rises above everything around it. Mountains are usually much steeper and taller than hills. Scientists say that a mountain is a landform that rises more than 300 meters, or about 1,000 feet, above the land around it. The very top of a mountain is called the peak. Some mountain peaks are covered in snow all year long or just part of the year. The tallest mountain on Earth is Mount Everest, and its peak is 8,848 meters, or about 29,000 feet, high!

How Do Mountains Form?

Mountains can form in a couple of different ways. One way is when the Earth’s tectonic plates, which are like giant puzzle pieces of the Earth’s surface, bump into each other. When these plates collide, they push the land upwards, creating mountains. This process takes a very long time, sometimes millions of years!

Another way mountains can form is through volcanic eruptions. When a volcano erupts, hot melted rock called magma comes out and flows onto the Earth’s surface as lava. When this lava cools down, it turns into solid rock, and over time, it can build up to form a mountain.

Thanks for joining this adventure into the world of mountains. See you next time!

  • Have you ever seen a mountain in real life or in pictures? What did it look like, and how did it make you feel?
  • Imagine you are climbing a mountain. What do you think you might see or hear on your way to the top?
  • Why do you think some mountains have snow on their peaks all year round, while others do not?
  • Mountain Building Experiment: Gather some clay or playdough and a flat surface. Divide the clay into two large pieces to represent tectonic plates. Slowly push the two pieces together and watch how they rise and form a “mountain.” Discuss with your friends or family how this is similar to the way real mountains are formed when tectonic plates collide.
  • Mountain Observation Walk: Take a walk in your neighborhood or a nearby park. Look for any hills or elevated areas. Imagine how these might be like small mountains. Draw a picture of what you see and label the peak, base, and any other features you notice. Share your drawing with your class and talk about how these landforms might have formed.
  • Volcano Model: With the help of an adult, create a simple volcano model using baking soda, vinegar, and a small container. Place the container in a mound of dirt or sand to represent a mountain. Add baking soda inside the container and pour vinegar over it to simulate a volcanic eruption. Watch how the “lava” flows and think about how this process can create mountains over time.

Venture into a natural environment and take a look around you. What landforms can you see? A landform is a unique feature or shape of the Earth’s surface. Valleys, hills, canyons, and plateaus are all examples of landforms.

Another type of landform that really stands out is mountains. A mountain is a very high area of land that rises above the land around it. Mountains are usually steeper and taller than hills. Scientists typically classify a mountain if it rises more than 300 meters, or about 1,000 feet, above the surrounding land. The highest part of a mountain is called the peak. Some mountains have peaks covered in snow for all or part of the year. The peak of the tallest mountain on Earth is Mount Everest, which has an elevation of 8,848 meters, or about 29,000 feet.

Mountains can form where the Earth’s tectonic plates meet and collide. This collision forces the land upward, forming mountains. This process occurs very slowly over millions of years. Mountains can also be caused by volcanic eruptions. During a volcanic eruption, magma erupts and flows onto the Earth’s surface as lava. Mountains can form when the lava cools into solid rock.
