Term
Condensation
Definition
The process of water changing from a vapor to a liquid.
Term
Convection
Definition
Warm, humid air will rise, while cooler air will flow downward.
Term
Precipitation
Definition
Water being released from clouds as rain, sleet, snow, or hail
Term
Infiltration
Definition
The process by which water on the ground surface enters the soil
Term
Runoff
Definition
Precipitation that reaches the surface of the Earth but does not infiltrate the soil.
Term
Evaporation
Definition
When radiant energy from the sun heats water, causing the water molecules to become so active that some of them rise into the atmosphere as vapor.
Term
Evapotranspiration
Definition
Water evaporating from the ground and transpiration by plants
Term
Atmospheric Advection
Definition
Water in atmosphere (clouds) is transported by wind from over sea to over land, and over land to over sea.
Term

Definition
Aquifer which has water entering it from land above it. Top layer of saturated soil is called Water Table.
Term
Confined aquifer
Definition
Aquifer that is bounded on top and below by impervious rock or soil (an Aquiclude).
Term
Water table
Definition
How deep you have to dig to reach water.
Term
Vadose zone
Definition

Term
What is convection and what is it’s relationship to condensation and clouds?
Definition
Convection is the process by which warm air rises and cooler air flows downwards. As the water rises, temperature drops and it turns to snow/ice.
Term
What are the processes of the Hydrolic Cycle?
Definition
Condensation, precipitation, infiltration, runoff, evaporation, evapotranspiration, atmospheric advection
Term
Where does water beading on a cold pop come from?
Definition
Water vapor from air is hitting the cold surface and condensing
Term
How does water re-enter the atmosphere?
Definition
Evaporation
Term
Which way is water transported due to atmospheric advection?
Definition
Over sea to over land or from over land to over sea
Term
What is the similarity and difference between runoff and infiltration?
Definition
Runoff and infiltration are similar because they both reach the earth's surface. They differ because infiltration is the only one that allows the precipitation to seep into the ground.
Term
Does more or less water travel to the atmosphere each year than is in the atmosphere? By about how much?
Definition

Glaciers - 2.1%
Atmosphere - .001%
Term
How does deforestation effect flooding?
Definition
With decreased infiltration and increased runoff, it is more likely to flood.
Term
What is an aquifer? What is the difference between an unconfined aquifer, and a confined aquifer?
Definition
An aquifer is porous layer of soil which becomes saturated with water. An unconfined aquifer is an aquifer with water entering it from above and a confined aquifer is an aquifer that is bounded on top and bottom by soil.
Term
In the slide with the figure on “Aquifer Types”, why does the water spurt out of one of the wells but not the one on the right?
Definition
The one on the left is a nonflowing well and the one on the right is a flowing well.
Term
How could a well removing water from an aquifer lead to damaged buildings?
Definition
If you pump too much water, the ground will fall in.
Term
Why is Mexico City sinking, and by how much?
Definition
depletion of water in aquifer due to lake drainage and city use..19 inches a year
Term
Where is the Ogallala Aquifer? What is happening to it? What is the relationship between this aquifers recharge and withdrawal? How would this “affect the future of America’s breadbasket”?
Definition
Stretches from South Dakota to New Mexico. Structure of the porous material is changing, limiting the ability to continue recharging.
Term
What three types of energy drive the weather?
Definition
Radiation (sun), thermal (heating of water and air) and mechanical (wind and water currents)
Term
What are a couple types of electromagnetic radiation that would be in a typical home?
Definition
Sunlight, microwave, tv, radio
Term
What characteristic of electromagnetic radiation is used to define different types?
Definition
the frequency and wavelength
Term
What part and percentage of the electromagnetic spectrum can we see?
Definition
Roughly the visible region is 300 nm to 650. so that's 350 nm total. The electromagnetic spectrum goes from 10 Megameters to 1 picometer. So the percentage of the spectrum occupied by visible light is tiny, just 3.5 X 10-9 divided by 10^19
Term
What blocks UV radiation in the atmosphere?
Definition
ozone layer
Term
What are our “electromagnetic radiation sensors”?
Definition
Our eyes
Term
What are harmful and helpful aspects of UV radiation?
Definition
Harmful - Sunburn on human skin and cataracts in our eyes.
Can cause damage at the molecular level to the fundamental building block of life— deoxyribonucleic acid (DNA)
Helpful - Builds Vitamin D
Term
What animal can “see” infrared radiation, and what does it use this ability to do?
Definition
Rattlesnakes can see infrared radiation and it allows them to see warmth...can see prey at night
Term
Why does IR radiation heat up water?
Definition
Incoming IR radiation makes the atoms within H20 molecules vibrate more. In this way, water adsorbs IR radiation and heats up.

In the “thought experiment” with the plant in a closed container, what happens to the O2 and CO2 in the light, and in the dark?
Definition
In the light the plant is using up CO2 but in the dark the plant is creating more CO2.
