Unit 1A Vocabulary List

purity: clean, free from impurities

filtrate: the liquid collected after it has been filtered (through sand/gravel filtration)

adsorb: to attract and hold onto a surface

percent recovery: percent of original foul water sample recovered as purified water

purified water: water that has been cleaned through a process of filtration/purification. The final step of purification is distillation

histogram: shows percent recovery obtained

range: the difference between the largest and smallest values in a data set

average/mean: average value found by adding all values together and dividing the sum by the total number of values

median: middle value

distillation: the process of separating salt from water through evaporation and condensation in a distillation apparatus

electrical conductivity: focuses on the presence of dissolved, electrically charged particles in water.

Tyndall Effect: the clarity of a water sample tested by passing a beam of light through each sample. Presence or absence of the Tyndall Effect.

pure: clean, purified

water cycle/hydrologic cycle: the cycle of water falling, evaporating into the air, condensing, and falling again

direct water use: water that can be directly measured

indirect water use: hidden uses of water

gaseous state: water vapor in the air

liquid state: in lakes, rivers, oceans, clouds, and rain

solid state: ice

surface water: a river or other body of water

groundwater: a well- must be pumped to the surface

aquifer: a water-bearing layer of rock, sand, or gravel

Homework #3

A.5 #1-3


1. a)The East: Stream/electric
    b)The South: Stream/electric
    c)The Midwest: Stream/electric
    d)The West: Irrigation/agricultural
    e)Alaska: Mining
    f)Hawaii:Irrigation/agricultural


2. The East uses there water mainly for Stream/electric uses, while the west is mostly agricultural. Because both sides have access to different oceans, it creates different opportunities to most efficiently use their water. The west has a vast amount of farms, while the east factories. 


3. The weather on the East and West coast affect their different areas of expertise when it comes to handling water. Alaska and Hawaii's culture effect their water purposes because of their climate and daily lifestyle. 

 

Homework #2

ISAS #1 1, 2,8-13,17

1. No, Jimmy Hendricks did use water, because the quantity of liquid in this container is insignificant when compared with the quantity of water used to make the container and possibly to irrigate the fruit trees and process the fruit juice. 
2. Water is used to make a loaf of bread by growing and processing the various components of each food. 
3. The worlds intake of water overtime has significantly increased, because the water unused by humans flows back into large bodies of water, and evaporates into the air. This is called the hydrologic cycle.
4.  -Glaciers  -Water vapor  -Oceans  -Rivers
5.  Because of the fact that only about 10% of water in the US goes to humans, and the rest to large bodies of water. Which justifies the previous quote.   
6. 77%
7. Glaciers and Ice Caps: 5.908/Lakes: 0.0252
8. Water is a renewable energy, so it is recycled over the course of many years. 
9. The discrepancy comes from the fact that the 1st number might be the mean, and the second number might have been all of the values added together, before the average. 

Homework #1

Pg. 7:


I personally feel that pure water is more critical than clear water, because if the water is pure, there is a significant chance that the water will be clear as well.
