Here's the matching of terms from Unit 7 Water Resources with their correct definitions/descriptions/examples:
Column A | Column B ---|---
- 3% | k. How much Fresh water there is on Earth (compared to Saltwater)
- Less than 1% | b. Of all the water on Earth, this is how much we all share at one time. Thank goodness the water cycle cleans and replenishes it for us...
- Artesian Well | n. A well located at the bottom of a slanted aquifer such that the water goes downhill with gravity, then up the well. No energy is required with this type of well.
- Aquifer | l. Area of Groundwater. We must dig a well into the saturated zone of a(n) ________ in order to reach the water.
- Permeable layer | o. Layer of underground rocks/soil/sand that allows water to flow through it.
- Impermeable layer | j. Layer of underground bedrock/clay that does NOT allow water to flow through. Instead, the water sits on top of this layer in an aquifer.
- Direct Water | m. Household usage is an example of this type of usage: drinking water, flushing toilets, showering, brushing teeth.
- Recharge | q. When precipitation soaks into the ground, causing an aquifer to refill.
- Water table | s. This is the very top of the saturated zone of an aquifer. It rises when it rains, and it lowers when there is overuse or drought.
- Drought | f. Lack of precipitation leads to this constraint on a community- forcing people to conserve water.
- Global average temperature/Global Warming | h. The cause for why the Poles are melting- which would flood coastlines.
- Economic Water Scarcity | g. When water is available, but the community lacks the funds/money to access or treat the water.
- Fall line | e. Natural boundary between a coastal plain and plateau. Cities were built in these locations throughout the US due to the access to the rivers *mainly for transportation of people and goods.
- Agricultural runoff | c. Fertilizers flow downhill with surface runoff into a nearby freshwater source.
- Algal Bloom | a. Too many nutrients in a freshwater source allows a(n) _____ to take over the top of the water, suffocating the living things below.
- Land subsidence | p. The sinking of the ground, when the groundwater beneath it depletes and can no longer hold the weight above.
- Hydropower | i. Energy created as moving water turns a turbine and operates a generator at a dam.
- Physical Water Scarcity | r. When water is simply not found in an area. Ex: Desert.
- Water privatization | d. Private companies take ownership of water sources/ operations. The opposite of public water. Highly debated!
- Sanitation | t. Plumbing that keeps wastewater away from natural water sources and drinking water.
