Rivers and Their Development Stages

What triggers the development stages of rivers?

• The amount of fish in the river

• The pollution level in the water

• The age of the river

• The temperature of the water

What shape are youthful rivers typically found to be?

• S-shaped

• V-shaped

• O-shaped

• U-shaped

How does the gradient of a river change as it moves from youthful to mature stage?

• Decreases slightly

• Decreases significantly

• Increases significantly

• Remains constant

What is the primary cause of erosion in youthful rivers?

• The speed of the water

• The width of the river

• The depth of the river

• The temperature of the water

What causes meanders to form in mature rivers?

• The type of fish

• The depth of the river

• The temperature of the water

• The speed of the water

What feature distinguishes mature rivers from youthful rivers?

• Faster water flow

• Wider channels

• Steep gradients

• Presence of large rocks

What is a common feature found along old rivers?

• Waterfalls

• Oxbow lakes

• Rapids

• Glaciers

Why do old rivers tend to have fewer tributaries?

• Due to increased pollution

• Because of human intervention

• Because tributaries join together upstream

• Due to the drying up of tributaries

What process leads to the formation of rejuvenated rivers?

• Pollution

• Uplifting

• Evaporation

• Erosion

What happens to the gradient of a river during rejuvenation?

• It becomes less steep

• It remains the same

• It becomes steeper

• It disappears
