Water Pollution
100
# species in an area
What is Species Richness
100
A natural body consisting of layers or horizons/organics
What is soil?
100
The boundary between vadose zones and phreatic zones
What is the water table
100
Open areas exposed to wind action. A forest being burnt is an example of this type of polluting source.
What is a fugitive source?
100
A specific spot where large quatities of pollutants are discharged. Can be applied to air or water pollution.
What is a point sourceÉ
200
The similarity between species found in one area and another area, calculated by the formula I=2C/(A+B)
What is Biogeographical Similarity?
200
The physical and/or chemical and/or biological process which produces soil.
What is weathering?
200
These three effects are consequences of overdrawing
What are reduction in surface water, land subsidence, and salt water intrusions
200
The direct products of combustion or evaporation.
What are primary pollutants?
200
A body of contaminated groundwater flowing from a specific source
What is a plume
300
The formula for species diversity
What is D= 1- sum[(Pi%)^2]
300
Smaller soil particles are created by the break down of this.
What is the parent material
300
1. Water which is bonded to the individual soil grains 2. Water that is held in the soil by matrix forces (will evaporate,transpire, be absorbed by plants) 3.Water which drains out of the root zone
What is SOIL WATER 1.What is HYDROSCOPIC water 2.What is CAPILLARY water 3.What is GRAVITATIONAL water
300
A car is an example of this kind of pollution source.
What is a mobile source.
300
A pollutant made up of hydrocarbons, which binds to surface of soil particles and in pore spaces. It disperses in the upper aquifer.
What is a LNAPL (light non aqueaous phase liquid)
400
The equation used to calculate % porosity
What is (1-[Pbulk/Pparticle])*100
400
A layer of mineral or organic soil/material
What is a horizon
400
These are 4 types of soil erosion.
What are splash erosion, sheet erosion, rill erosion, and gully erosion
400
The interaction of direct products of combustion or evaporation with constituents of the atmosphere.
What is a secondary pollutant?
400
A natural process in water bodies characterized by a development towards and environment rich in nutrients and an increase in primary productivity.
What is EutrophicationÉ
500
The equation for settling velocity
What is v=[(ps - pw) g(d^2)] / 18n v --> velocity ps --> particle density pw --> fluid density (water=1) d --> particle diameter g --> acceleration due to gravity n --> viscosity of fluid
500
The components of a soil profile from top to bottom
What is O Horizon - HUmus A Horizon - Topsoil E Horizon - zone of leaching B Horizon - Subsoil C Horizon - Weathered parent material
500
This is the process of supplying water to croplands by artificial means, and 3 techniques by which it is done.
What is irrigation? What are gravity flow, drip irrigation, and center pivot?
500
These are the layers of a stratified lake
What are epilimnion, thermocline, hypolimnion?
500
A state in which the [DO] < 2mg/L. A state in which [DO] = 0mg/L.
What is hypoxia? What is anoxia?
