Groundwater - Chapter Summary and Learning Objectives
Learn why groundwater is often treated as a nonrenewable resource and explore how excessive extraction of groundwater has led to the sinking of land - also known as subsidence. After watching our series of brief video lessons, you should be able to do the following:
- Explain how porosity, permeability, aquitards and aquifers can affect the rate of groundwater movement.
- Describe how hot springs and geysers and formed.
- Differentiate among dug, driven and drilled wells.
- Detail different environmental problems that have arisen with regards to groundwater.
- Explain the role of groundwater in the formation of caverns and sinkholes.
|Groundwater System: Definition & Geological Role||Define groundwater and describe its distribution and geological role.|
|Factors that Influence Groundwater Movement||Describe groundwater distribution and movement and identify factors that influence its rate of movement.|
|Springs: Definition, Formation & Types||Explore formation of and types of springs.|
|Wells: Definition & Types||Learn about the nature of wells and identify different types, including artesian wells.|
|Environmental Problems Associated with Groundwater||Identify environmental problems associated with groundwater.|
|Caverns and Sinkholes: Definition, Causes & Effect on Groundwater||Describe the effect of groundwater on Earth's geology.|
1. Groundwater System: Definition & Geological Role
Surprisingly, most of Earth's liquid freshwater is not where you might think! In this video lesson, you will learn about groundwater, as well as the important roles it plays in sustaining life and shaping Earth.
2. Factors that Influence Groundwater Movement
The movement of groundwater underneath us is influenced by several factors. In this video lesson, you will learn what these factors are and how they affect how and where groundwater moves.
3. Springs: Definition, Formation & Types
In this video lesson, you will learn about springs and how they form. You will also understand how springs are classified based on how they flow as well as how strongly they flow.
4. Wells: Definition & Types
Wells are used all over the world and are an important source of water for many people. In this video lesson you will identify different types of wells, as well understand their underground source of water.
5. Environmental Problems Associated With Groundwater
Groundwater is an important natural resource, but like many of our other resources, it's affected by the surrounding environment and human activities. In this video lesson, you'll learn about some of the environmental problems associated with groundwater and why groundwater is especially vulnerable to them.
6. Caverns & Sinkholes: Definition, Formation & Effects
Groundwater can have dramatic effects on Earth's landscape, both above and below ground. In this video lesson you will learn about caverns and sinkholes, both of which are directly related to groundwater movement.
