The Properties of Water
Water is made of this kind of this many atoms. Describe how these atoms are charged.
2 hydrogen (positively charged), 1 oxygen (negatively charged)
This is water that falls to Earth as rain, snow, sleet, or hail.
What is precipitation?
A ____ is a stream or smaller river that feeds into a main river
What is a tributary?
This is covered in water for much or even all of the year.
What is a wetland?
Water that fills cracks and spaces in underground soil and rock layers is called:
What is groundwater?
This is the tightness across the surface of water.
What is surface tension?
Most of Earth's water is found in:
What are oceans?
What is a reservoir?
These are the three common types of wetland environments:
What are bogs, marshes, and swamps?
Sand and gravel are examples of ______ materials
What are permeable materials?
This allows water to stick to other things and dissolve other things.
What is water's polarity?
Plants need water to do __________ and grow
What is photosynthesis?
This is the land area that supplies water to a river system.
What is a watershed?
These are the three main threats to the Florida Everglades:
What are agriculture, development, and the introduction of new species?
Clay and granite are examples of _______ materials.
What are impermeable materials?
This is water's ability to stick to itself and to surrounding materials.
What is capillary action?
This is when a gas changes to its liquid state.
What is condensation?
These are the two seasonal changes that can occur in lakes.
What are thermal stratification (in Summer) and mixing or "lake turnover" (in Fall and Spring)?
The water in bogs tends to be acidic, and ____ thrive in these conditions
What are mosses?
In a(an) ________, water rises because of pressure within an aquifer.
What is an artesian well?
This is the amount of heat needed to increase 1 gram of a substance by 1 °C.
This is measured in J/kg K)
What is specific heat?
Does water have a high or low specific heat?
Plants breathe in carbon dioxide and breathe out oxygen through their leaves. They lose water while breathing, which is called:
What is transpiration, a type of evaporation?
Water doesn’t cross between watersheds because __________ are in the way
What are divides?
In addition to providing habitats for many living things, wetlands also serve these two other important functions:
- Wetlands act as natural water filters
- They also help control floods by absorbing extra runoff from heavy rains.
A place where the water table meets the surface is known as a:
What is a spring?
This is a substance that gets dissolved.
What is a solute?
This is when molecules throughout an entire liquid absorb enough energy to change to the gaseous state.
What is boiling?
These are two things eutrophication can do to a body of water (i.e. a pond or lake)
Eutrophication, or too many nutrients, can cause too much algae to grow on the water body’s surface: blocking sunlight, killing water plants / using up all the oxygen, killing water animals.
Eutrophication can also fill a body of water with nutrients / sediment / dirt / decaying matter.
This is what is being done to preserve the Everglades.
Bonus 100 pts if you can name one of the organizations helping to do this that the textbook mentions
One plan involves building an elaborate system of pipes and canals to refill some drained areas with fresh water.
US Army Corps of Engineers, National Park Service
List the two water zones and what separates them in order from top to bottom and be sure to mention whether they are permeable or impermeable. What is at the bottom of these things? Is it permeable or impermeable?
Unsaturated zone (permeable)
Water table (permeable)
Saturated zone (permeable)
Solid rock (impermeable)
