• A type of rock.

• A mountain top.

• A cloud formation.

Why are channels important to ecosystems?

• They provide shelter for animals.

• They direct water and nutrients, supporting diverse ecosystems.

• They are a source of minerals.

• They prevent erosion.

Which factor does NOT affect channel formation?

• Water Volume

• Slope

• Rock Type

• Rock Color

Which is an example of an artificial channel?

• Canal

• River

• Stream

• Valley

How do artificial channels differ from natural channels?

• Artificial channels are human-made and often straight, unlike natural winding paths.

• Artificial channels are formed by glaciers.

• Artificial channels are made by wind.

Which type of channel is formed by glaciers?

• River Channel

• Glacial Channel

• Artificial Channel

• None of the above

What process primarily forms channels over time?

• Sedimentation

• Erosion

• Volcanic activity

• Earthquakes

Why does a larger volume of water cause more erosion?

• It increases the temperature of the water.

• Larger water volumes exert more force, increasing erosion.

• It decreases the speed of water flow.

• It reduces the amount of sediment.

Which statement about glacial channels is true?

• Formed by the wind

• Always dry

• Created by glacier movement

• Found in deserts

What is the primary role of channels in landscapes?

• To create mountains

• To direct water flow

• To form deserts

• To produce minerals
