Study Notes
Monitoring and Protecting Aquatic Systems
- To monitor and protect aquatic systems, we need to understand how water is used and its impact on the environment
- Identifying ways to conserve water at home can help reduce waste and protect aquatic ecosystems
Water at Home
- Tracking water usage at home can help calculate the amount of water used by family members
- Recording water usage can help identify areas for improvement and opportunities for conservation
Glaciers
- Continental glaciers are huge masses of ice and snow that cover large areas of land
- They occur near the North and South poles, covering areas such as Greenland and Antarctica
- Glaciologists study glaciers to understand their age, movement, and impact on the environment
Trudy Wohhleben's Research
- Trudy Wohhleben is a glaciologist who studies how glaciers affect the weather and vice versa
- She collects data on temperature, wind, and snowfall to understand glacial movement and weather patterns
Lakes, Ponds, and Wetlands
- Lakes and ponds are large holes in the ground filled with standing water
- Lakes differ from ponds in depth, with sunlight unable to reach the bottom of a lake
- Wetlands can occur in low-lying areas and are saturated with water all or most of the time
- Marshes are shallow water wetlands that remain wet throughout the year
Explore the importance of protecting aquatic systems for both human and environmental well-being. Analyze pages 472-473 to learn more about preserving these ecosystems.
