Ravine facts for kids
A ravine is a type of landform that looks like a deep, narrow valley. It is usually smaller and narrower than a canyon. Ravines are often formed naturally by the power of erosion, especially from flowing water.
Ravines typically have very steep sides. Their slopes can be quite sharp, often between 20% and 70% in gradient. Sometimes, you can find small streams or rivers flowing at the bottom of a ravine, which continue to shape the land over time.

What is a Ravine?
A ravine is a deep, narrow valley with steep sides. It is created when water, like a river or stream, cuts into the land. Over many years, this flowing water wears away the soil and rock. This process is called erosion.
Ravines are smaller than canyons. Canyons are much larger and wider. Think of a ravine as a smaller version of a canyon. They are a common sight in many parts of the world.
How Ravines Form
Ravines are mainly formed by the natural process of erosion. Here’s how it works:
- Water Flow: When rain falls, water flows over the land. This water often collects into small streams.
- Cutting into the Earth: As these streams flow, they pick up bits of soil and rock. Over time, this moving water slowly cuts deeper and deeper into the ground.
- Steep Sides: The water carves a channel. The sides of this channel become steep because the water keeps eroding the bottom faster than the sides.
- Time and Weather: It takes a very long time for a ravine to form. Weather, like rain and wind, also helps shape the ravine's sides.
Sometimes, a sudden flood can also quickly carve out a ravine. This is especially true in areas with soft soil.
Where Can You Find Ravines?
Ravines can be found in many different places around the world. They are common in areas where:
- Hills and Mountains: Water flows downhill with more force in hilly or mountainous regions. This makes it easier for erosion to occur.
- Soft Rock and Soil: Areas with softer types of rock or soil erode more easily. This allows ravines to form faster.
- Heavy Rainfall: Places that get a lot of rain often have more ravines. More water means more erosion.
You might see ravines near coastlines, in forests, or even in deserts. They are a natural part of the landscape.
Characteristics of Ravines
Ravines have several key features that make them unique:
- Steep Slopes: The sides of a ravine are usually very steep. This is a defining characteristic.
- Narrow Bottom: The bottom of a ravine is often narrow. It might have a small stream or river flowing through it.
- V-shaped Cross-section: Many ravines have a V-shape when you look at a cross-section. This shape shows how the water has cut into the land.
- Vegetation: Plants and trees often grow on the steep sides of ravines. This vegetation can help hold the soil in place.
Ravines can range in size. Some are quite small, while others can be very deep and long.
