A cirque.
Well, let me put on my ice-cold thinking cap! If we're talking about a landform created by a glacier, one standout choice would be a cirque! It's like a cozy hollow scooped out by a glacier, forming a little bowl-shaped thingy. So, go ahead and circle that 'cirque' option with icy determination!
A cirque is the landform created by a glacier.
To identify which landform is created by a glacier, you can follow these steps:
1. Understand what a glacier is: A glacier is a large mass of ice that moves slowly over land. As a glacier moves, it erodes the land, shaping it in distinctive ways.
2. Familiarize yourself with different landforms created by glaciers: Glaciers can sculpt various landforms, including U-shaped valleys, cirques, arêtes, horns, and moraines.
3. Analyze the given options:
- Barrier island: Barrier islands are long, narrow landforms that are created by the action of waves and currents, not glaciers. So it is not the correct answer.
- V-shaped valley: V-shaped valleys are typically formed by rivers or streams as they erode the land over time. Glaciers tend to create U-shaped valleys rather than V-shaped valleys. So it is not the correct answer.
- Cirque: A cirque is a half-open amphitheater-like hollow formed at the head of a valley glacier. It is typically characterized by steep walls and a bowl-like shape. Cirques are indeed created by glaciers, which makes it the correct answer.
- Cave: Caves are formed through various geologic processes, such as the dissolution of limestone by water. While certain features within a cave may be influenced indirectly by glaciation, caves themselves are not directly created by glaciers. So it is not the correct answer.
So, the landform created by a glacier is a cirque.
