Problem Overview:

The task is to complete a landform worksheet by providing definitions and pictures for different types of landforms. The worksheet includes the following landforms: Mountain, Valley, Canyon, and Plain. Definitions are already provided, and images are included to illustrate each landform.

Solution Explanation:

#### 1. Mountain
- Definition: A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.
- Image: The image shows a tall, rugged structure with steep sides and a peak, characteristic of a mountain. It has visible exposed rock and snow-capped peaks, which align with the definition provided.

#### 2. Valley
- Definition: Valleys are the most predominant landforms on the face of the earth. They are found on virtually every continent on planet earth, along sea bottoms, and other planets. Valleys assume a wide array of forms, from broad plains to steep-sided canyons. The kind of valley created depends on numerous factors, for instance, the erosion medium, the slope of the land, the nature of rocks and soils found in the area, and the time the valley takes to form.
- Image: The image depicts a low-lying area between two hills or mountains, with a flat or gently sloping surface. This is characteristic of a valley, as it represents a depression in the landscape where water often flows.

#### 3. Canyon
- Definition: A canyon is a deep, narrow valley with steep sides. “Canyon” comes from the Spanish word cañón, which means “tube” or “pipe.” The term “gorge” is often used to mean “canyon,” but a gorge is almost always steeper and narrower than a canyon.
- Image: The image shows a deep, narrow valley with steep, rocky walls. This matches the description of a canyon, which is characterized by its depth, narrowness, and steep sides.

#### 4. Plain
- Definition: A plain is a broad area of relatively flat land. Plains are one of the major landforms, or types of land, on Earth. They cover more than one-third of the world’s land area. Plains exist on every continent.
- Image: The image depicts a vast, flat expanse of land with no significant elevation changes. This is characteristic of a plain, which is defined by its flatness and broad, open terrain.
