Ch 27.3 Notes Flashcards
- What percentage of water on Earth is salt water?
97%
- What percentage of water on Earth is freshwater?
3%
- Where is the majority of freshwater found?
(2%)It is found in glaciers
- Where is the smaller percentage of freshwater found?
(1%)It is found in lakes, rivers, and stored as ground water
- What is precipitation?
When water vapor in the air cools and condenses to form liquid water or ice crystals. Forms of precipitation are rain, snow, sleet, and hail.
- What is Runoff?
Water running off the land surface.
- What is infiltration?
The process by which water enters Earth and becomes groundwater below the surface.
- What is transpirtation?
When plants release water vapor into the atmosphere through their leaves.
- What is evaporation?
When water enters the atmosphere as water vapor.
- What is condensation?
Where water vapor molecules collide with other water molecules to form droplets.
- What is the water cycle?
The water cycle is where water from the land enters the atmosphere and then eventually returns back to the land.
- What is an unsaturated zone for groundwater storage?
A porous area where water easily passes through
- What is a saturated zone for groundwater storage?
beneath the unsaturated zone, where water completely fills the pore space
- What is a water table?
The upper boundary of the saturated zone
- What does it mean if sediment is permeable?
It means that water is able to infiltrate the ground easier.
- What is an aquifer?
a rock unite that can transfer water through its pore space
- What is the name of the Great Plains Aquifer?
Ogallala Aquifer
- How many states does the Great Plains Aquifer run through?
8 states
- What are the names of the states that the Great Plains Aquifer runs through?
South Dakota, Wyoming, Nebraska, Colorado, Kansas, Oklahoma, New Mexico, and Texas.
- What is an aquitard?
Is a layer of sediment that doesn’t allow water to pass through it.
- How are water springs formed?
Springs form where the water table naturally meets Earth’s surface
- What is an artesian well?
Wells drilled into pressurized aquifers, forms when an aquifer is sandwiched between aquitards, pressure causes water to flow up into the well
- What is a cone of depression?
Where the direction flows towards the well
