Water Smart: Water on Earth - Wetlands

Wetlands are vital ecosystems that provide habitats for diverse species, including endangered ones. They play a crucial role in flood control by storing excess water and preventing damage. Wetlands also purify water by trapping sediments and pollutants before they reach the ocean. Additionally, they protect land and communities from storm damage by buffering the force of wind and waves. The water levels in wetlands vary with seasons and precipitation, and they can be either freshwater or saltwater.

What is one of the key roles of wetlands in the ecosystem?

• Blocking sunlight

• Reducing biodiversity

• Increasing soil erosion

• Providing a habitat for many species

How do wetlands contribute to the life cycle of fish?

• By blocking sunlight

• By reducing oxygen levels

• By providing a breeding ground

• By increasing water temperature

In what way do wetlands help in managing floodwaters?

• By creating more rivers

• By storing excess water

• By increasing rainfall

• By evaporating water quickly

What is one way wetlands help in cleaning water?

• By adding pollutants

• By reducing water flow

• By trapping sediments

• By increasing water temperature

How do wetlands protect land and communities from storms?

• By reducing land elevation

• By attracting more storms

• By increasing storm intensity

• By blocking wind and waves
