Welcome to an exciting journey where we explore the fascinating landforms of our planet! Have you ever hiked through a canyon or skied down a snowy mountain? Maybe you live in a flat valley with no hills in sight. These are all examples of landforms, which are the natural features on Earth’s surface.
Landforms are special shapes and features on the Earth’s surface. They can be big, like mountains and plains, or smaller, like hills and valleys. Some landforms, like alluvial fans, might be new to you. An alluvial fan is a fan-shaped area made of clay and dirt that forms when a river slows down.
Landforms are created by nature and can take a very long time to form—sometimes thousands or even millions of years! They are made from different materials. The Earth’s crust, which is the rocky layer around our planet, is one of these materials. Dirt, which is a mix of broken rocks and old plants and animals, is another. Fossils, which are remains of ancient living things, can also be found in the dirt or deeper in the crust.
There are also sediments, which are tiny particles that settle on the Earth’s surface because of wind, water, or ice. These sediments help form landforms, just like the alluvium in alluvial fans. And don’t forget about volcanoes! When volcanoes erupt, they release melted rock that creates new landforms.
There are many kinds of landforms on Earth. Here are some of the most common ones:
Mountains are the tallest landforms, with steep sides and a peak at the top. The Himalayas are the tallest mountain range, and Mount Everest is the highest peak at 29,032 feet!
Valleys are low areas between mountains. They are often formed by rivers. Death Valley in the United States is the lowest, hottest, and driest valley in North America.
Plains are flat areas. Some, like the Great Plains, are in the middle of land, while others are near oceans and called coastal plains.
Plateaus are flat areas higher than the land around them, often with steep sides. The Colorado Plateau is a famous example.
An island is land surrounded by water. Volcanoes often create islands. Australia is a continent and an island, and Hawaii has eight major islands.
Lakes are bodies of water surrounded by land. Most lakes have freshwater, but some, like the Great Salt Lake, have saltwater.
Oceans are the largest bodies of water, covering 71% of Earth’s surface. There are five main oceans: Pacific, Atlantic, Indian, Arctic, and Southern.
Coasts are where the ocean meets the land, often featuring beaches. Deserts are dry areas with little rain and lots of sand.
Rivers are long, flowing bodies of water that move through land and into lakes or oceans. The Nile River is the longest in the world, stretching over 4,100 miles.
Each landform makes our world unique and beautiful. They change over time as rivers widen, mountains erode, and coastlines shift. Next time you explore a new place, think about the landforms around you and how they came to be.
Thank you for learning with us! Keep exploring and discovering the wonders of our planet.
Landform Scavenger Hunt: Go on a scavenger hunt in your neighborhood or local park to find different landforms. Look for hills, valleys, or even small streams. Draw a picture of each landform you find and write a sentence about how you think it was formed. Share your discoveries with your family or classmates!
Create Your Own Landform: Use clay or playdough to create a model of your favorite landform. It could be a mountain, a valley, or even an island. Once you have made your model, explain to someone how this landform might have been formed over time. You can also use small toys or figures to show how people or animals might live in or around your landform.
Landform Story Time: Imagine you are an explorer discovering a new landform for the first time. Write a short story about your adventure. What do you see? How does the landform look and feel? What animals or plants might live there? Share your story with a friend or family member and ask them what landforms they would like to explore.
Sure! Here’s a sanitized version of the transcript:

Welcome! In this video, we will explore various types of landforms. Have you ever gone hiking in a canyon or skied down a snowy mountain? You may live in a valley without a hill for miles. Earth has many features like these, known as landforms.
So, what is a landform? A landform is a specific feature on the surface of the Earth, ranging from large formations like plains, plateaus, and mountains to smaller features like hills and valleys. There are many types of landforms, some of which you may not have seen before. For example, have you heard of an alluvial fan? This is a fan-shaped mass of alluvium, a type of clay sediment that forms as the flow of a river slows down.
Like alluvial fans, other landforms are shaped by nature and can take thousands or even millions of years to form. Landforms are made up of various materials. Some of these materials are common, like the Earth’s crust, which is the rocky covering around the planet, and dirt, a mixture of broken rocks and decomposed plant and animal material. Fossils, the remains of things that once lived on Earth, are less common and can be found in the dirt or deeper in the crust.
There are also sediments, which are particles that settle on the Earth’s surface due to wind, water, or ice. Similar to the alluvium that forms alluvial fans, these sediments contribute to landforms.
Can you guess what the last material is? Here’s a hint: it comes from giant openings in the Earth’s surface. If you guessed volcanoes, you’re correct! Volcanoes erupt melted rock, which creates various landforms, just like sediments, dirt, fossils, and the Earth’s crust.
These different materials make up the landforms on Earth. Some may be underwater, while others sit atop mountains or deep in valleys. There are about ten different kinds of landforms on Earth: mountains, valleys, plains, plateaus, islands, lakes, oceans, coasts, deserts, and rivers.
Let’s start with mountains. Mountains are the highest landforms on Earth, typically shaped like upside-down ice cream cones with steep sides and ridges. Each mountain has a peak at the top. The Himalayas are the tallest mountain range in the world, with Mount Everest being the highest peak at an elevation of 29,032 feet.
Valleys, on the other hand, are low-lying areas that sit between mountain ranges and other large landforms. They are formed over time as rivers flow from the mountains above. The most well-known valley in the United States is Death Valley, which is the lowest, hottest, and driest area in North America.
Plains are flat areas on the Earth’s surface. Some plains, like the Great Plains, are located in the middle of land masses, while others are near oceans and are called coastal plains. The Great Plains span across several states in the United States.
Plateaus are flat areas situated higher than the surrounding land, often with steep sides and cliffs. Famous plateaus include the Colorado Plateau and the Anatolian Plateau. Some plateaus are even underwater, like the Seychelles Plateau.
An island is a piece of land surrounded by water. The melted rock from volcanoes often forms islands, which can be found near the coasts of countries. For example, Australia is a continent that is also an island, and Hawaii consists of eight major islands.
Lakes are bodies of water surrounded by land, filled with freshwater, although some, like the Great Salt Lake, contain saltwater. There are millions of lakes worldwide, varying greatly in size.
Oceans are the largest bodies of water on Earth, covering about 71% of the planet’s surface and holding over 96% of all water. There are five main oceans: the Pacific, Atlantic, Indian, Arctic, and Southern Oceans.
Coasts are where the ocean meets the land, and beaches can be found along these coasts. Deserts are hot, dry places with very little rainfall, often characterized by sand dunes.
Rivers are long bodies of water that flow through land and into other bodies of water, such as lakes and oceans. The Nile River is the longest river in the world, stretching over 4,100 miles.
Each of these landforms contributes to the uniqueness of our world. Many take thousands or millions of years to form and are constantly changing. Rivers may widen, mountains may erode, and coastlines may shift due to natural events.
Next time you’re in a beautiful place, think about the landforms around you and imagine how they all began.
