Glaciers form U-shaped valleys due to their ability to erode and transport large amounts of rock and sediment. As glaciers move downhill, they carve and widen the valley floor, creating a broad and deep U-shaped profile. In contrast, rivers mainly erode the valley through the process of hydraulic action, which tends to create narrower and steeper V-shaped valleys.

Which of these could be formed by glaciers?
U-shaped valleys, moraines, and cirques are landforms that can be formed by glaciers. U-shaped valleys are carved out by the movement of glaciers, moraines are piles of debris left behind by glaciers, and cirques are bowl-shaped depressions at the head of a glacier.
What are glaciers made up of?
Glaciers are made up of snow that accumulates over time and compresses into dense ice. The ice in glaciers can vary in age from a few years to thousands of years old. Glaciers may also contain sediment, rocks, and debris that they pick up and carry as they move.
Why are glaciers called nature's bulldozers?
Glaciers are often called nature's bulldozers because they are capable of reshaping landscapes through the process of glaciation. As glaciers move, they pick up rocks and debris, which act like a bulldozer pushing and carving out valleys, mountains, and other features. This process helps to create and shape the Earth's physical geography over time.
As glaciers melt the land underneath sinks?
Yes, when glaciers melt, they contribute to rising sea levels rather than causing the land underneath to sink. The weight of the ice depresses the land beneath, and when it melts, the land gradually rebounds over time in a process known as isostatic rebound.
Ask us What force is present at a divergent boundary?
A divergent boundary are two tectonic plates that are moving away from each other, rather than into each other. This can cause rifts, valleys, and ocean ridges.
Are there any valleys in Denmark?
No, Denmark is a relatively flat country with no significant valleys. The landscape is characterized by rolling hills and coastal plains rather than deep valleys.

Are there any famous glaciers near Antarctica?
Antarctica is a continent that covers 10% of the earth's surface. Ninety-eight percent of it is covered with an ice sheet. The mountainous terrain of the continent means that there are thousands of glaciers on the continent. "Near Antarctica' is the Southern Ocean, which may be home to icebergs calved off continental glaciers. Rather than 'famous glaciers', Antarctica is home to ice shelves, the most famous, perhaps, being the Ross Ice Shelf, which is about as large as France.

What does Antarctica look like?
It has a lot of ice, it's very cold, and rather uninhabited.
Is there ice in Costa Rica?
If you mean ice as in freezer ice,then yes there is! But here are no ice burgs,snow,ice glaciers or any formed ice,rather then the ice in the freezer.
What plain is in st thomas?
St. Thomas, a part of the Virgin Islands, is characterized by rolling hills and valleys rather than plains. The terrain is mainly hilly with mountains, forests, and coastline.
Did erosion create a lot of valleys on the surface of the moon?
Valleys on the surface of the moon are mainly thought to have been formed by ancient tectonic and volcanic processes rather than erosion. While some erosion due to micrometeoroid impacts may have occurred, it is not considered the primary mechanism for valley formation on the moon.
These are elevated landforms that are flat rather than peaked?
Plateaus are elevated landforms that are flat rather than peaked. They are typically situated between valleys and higher mountain ranges. Plateaus are often characterized by their extensive, flat top surface that can be high above sea level.
As glaciers melt the land underneath sinks?
Yes, when glaciers melt, they contribute to rising sea levels rather than causing the land underneath to sink. The weight of the ice depresses the land beneath, and when it melts, the land gradually rebounds over time in a process known as isostatic rebound.
Why do you think ancient Chinese cities were founded in the eastern low lying areas rather than in the west?
The river valleys broadened as they flowed east out of the western mountains, and so supported the burgeoning population and growing cities there.
