What is a kettle lake?

Back

A kettle lake is a body of water formed when glaciers erode an area, creating a shallow pit that fills with sediment and melted glacier water.

Front

How is a kettle lake created?

Back

Glaciers erode away at an area, causing a shallow pit to form. Over time, this pit is filled with sediment and melted water from the glacier.

Front

What is folding in geology?

Back

Folding is a constructive force where originally flat, level surfaces are bent or curved due to pressure and high temperature.

Front

What is the difference between island arcs and hot spots?

Back

Hot spots only form one volcano at a time, while many island arcs can be formed at once.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, two tectonic plates move away from each other.

Front

What is a moraine?

Back

A moraine is a landform made of debris deposited by a glacier.

Front

What is the role of glaciers in shaping the landscape?

Back

Glaciers erode land, create valleys, and form features like kettle lakes and moraines.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive slab of Earth's lithosphere that moves and interacts with other plates.

Front

What is the significance of hot spots in geology?

Back

Hot spots are volcanic regions fed by underlying mantle that is anomalously hot, leading to the formation of volcanoes.
