Study Notes
Wetlands Overview
- Wetlands form when groundwater surfaces and floods surrounding land, creating diverse ecosystems.
- A pond is a permanent shallow freshwater body characterized by plant life throughout its extent.
Groundwater and Streams
- Groundwater is located below Earth's surface and plays a vital role in feeding rivers.
- Streams on either side of the Great Divide supply different watersheds, influencing water flow and ecology.
Water Bodies and Runoff
- Runoff consists of water from precipitation (rain and snow) that travels towards streams, impacting water levels and ecosystems.
- Reservoirs, both natural and human-made, serve as large lakes that provide freshwater supply for various needs.
River Systems
- Rivers increase in size as tributaries join, contributing additional water and influencing habitat complexity.
- Most of Earth's freshwater is located near the poles, highlighting geographical distribution issues.
Ponds and Lake Ecology
- Ponds form when water gathers in low-lying areas, creating habitats for various plants and animals.
- Light penetration affects lake ecology; sunlight often fails to reach lake bottoms, preventing plant growth in deeper areas.
Marshes and Bogs
- Differences between wetlands include marshes, which have shallow water, while bogs contain deeper areas with unique ecosystems.
Icebergs
- Icebergs originate from large ice sheets at the poles, breaking off due to melting or calving processes.
Swamps
- Swamps are wetlands predominantly found in warm, forested regions, featuring a rich variety of plant and animal life.
