Water Cycle and Rivers

What is a gletsjer?

• An island

• A glacier

• A desert

• A volcano

Explain what a meander is in a river.

• A meander is a waterfall in a river.

• A meander in a river is a winding curve or bend in the river's course.

• A meander is a circular pool in a river.

• A meander is a straight line in a river.

Describe what happens at the delta of a river.

• The delta is a dry and arid region

• The delta disappears during heavy rainfall

• The river splits into multiple smaller channels and deposits sediment to form a fan-shaped landform.

• The river flows uphill towards its source

What is the purpose of a rioolwateringszuiveringsinstallatie?

• The purpose of a rioolwateringszuiveringsinstallatie is to clean and purify wastewater before releasing it back into the environment.

• To promote environmental degradation

• To increase water pollution

• To reduce the quality of drinking water

How does a gletsjer contribute to the water cycle?

• By accumulating snow and ice that eventually melts and flows downstream as water.

• By reducing the overall water content in the atmosphere through evaporation.

• By absorbing water vapor from the atmosphere and releasing it as snow and ice.

• By creating clouds that produce rain and snowfall.

Why are meanders important for river ecosystems?

• Meanders create diverse habitats, improve water quality, and regulate water flow.

• Meanders disrupt habitats, degrade water quality, and cause flooding.

• Meanders have no impact on habitats, water quality, or water flow.

• Meanders are only important for aesthetic purposes and do not benefit river ecosystems.

How does a delta form in a river?

• Sediment carried by the river is deposited at the river mouth due to a decrease in water velocity.

• The river widens due to erosion upstream

• The river carries more water downstream

• The river flows faster at the mouth

What is the main function of a rioolwateringszuiveringsinstallatie?

• To treat wastewater and remove contaminants

• To provide internet access

• To generate electricity

• To purify drinking water

Where can gletsjers be found?

• Urban areas and farmlands

• Polar regions and high mountain areas

• Deserts and rainforests

• Oceans and lakes

What are the characteristics of a meander in a river?

• Narrow, linear shape due to sediment buildup

• Straight, direct path caused by erosion

• Circular, spiral pattern formed by volcanic activity

• Winding, sinuous pattern caused by erosion and deposition processes
