Which layer does most weather occur ?
troposphere
stratosphere
mesosphere
thermosphere
What does the ozone layer do for us?
it protects us from meteors
It protects us from ultraviolet (UV) radiation
It protects us from violet solar flares
It does not help us at all
Which atmospheric layer is very hot and contains "light showers" known as auroras?
stratosphere
exosphere
mesosphere
thermosphere
As one increases elevation through the ENTIRE atmosphere what characteristic of the atmosphere steadily decreases?
Electric potential
Air Pressure
Air Temperature
Air Composition
Temperature increases as altitude increases in both the stratosphere and the thermosphere. What is the main difference between these two layers?
The temperature increases in the stratosphere because of aurora borealis, and in the thermosphere because of the jet stream.
The temperature increases in the stratosphere because ozone absorbs ultraviolet radiation, and in the thermosphere because of direct exposure to the sun.
The temperature increases in the stratosphere because of direct exposure to the sun, and in the thermosphere because ozone absorbs ultraviolet radiation.
The temperature increases in the stratosphere because of the jet stream, and in the thermosphere because of aurora borealis.
A river is a _____________reservoir.
man-made
natural
freshwater
surface water
A certain area received a large amount of rain and some of it remained on top of the soil. What happened to the rest of this water?
condensed to form clouds
seeped into the ground
used by plants
evaporated into the air
The only natural source for freshwater is in glaciers.
TRUE
FALSE
CANNOT BE DETERMINED
Which BEST describes how the total amount of water present in the hydrosphere varies over time?
The total amount of water in the hydrosphere decreases over time due to the process of evaporation.
The total amount of water in the hydrosphere increases over time due to the process of precipitation.
The total amount of water in the hydrosphere remains the same over time, but changes form due to the water cycle.
The total amount of water in the hydrosphere both decreases and increases over time due to competing processes such as evaporation and precipitation.
Which represents the percentage of distribution of water on Earth?
3% freshwater, 97% salt water
97% freshwater, 3% salt water
71% freshwater, 29% salt water
70% freshwater, 30% salt water
The majority of aquatic creatures prefer a pH range of 6.5-9.0. If it is too low or high they will die
True
False
CANOT BE DETERMINED
Which is a true statement of the diagram above?
As temperature increases dissolved oxygen increases
As temperature decreases dissolved oxygen decreases
As temperature increases dissolved oxygen decreases
None of the above
Ground level ozone (also known as tropospheric ozone) is ______________________.
a significant source of air pollution and contributes to the formation of smog
also found in the exosphere
found only in rural areas
a significant source of air pollution and contributes to the increase in the hole in the ozone layer.
We used bioindicators to measure the quality of water. What is a bioindicator?
any living creature in water
eutrophication
An organism sensitive to its environment
a turbidity tube
These are the physical parameters of water quality except
turbidity
salinity
temperature
BOD (biochemical oxygen demand)
Which of the following best describes soil as a nutrient cycler?
Soil microorganisms convert unusable atmospheric nitrogen into nitrates that are used by plants in a process known as Nitrogen Fixation
When water and air pass through soil, contaminants are absorbed in the soil and degraded by soil microorganisms.
Soil maintains plant and animal life by providing healthy ecosystems where they can thrive and reproduce.
Human infrastructure relies on soil support for anchorage for long-term stability
Which describes the filtration capacity of soil?
Human infrastructure relies on soil support for anchorage for long-term stability.
When water and air pass through soil, contaminants are absorbed in the soil and degraded by soil microorganisms.
Soil maintains plant and animal life by providing healthy ecosystems where they can thrive and reproduce.
Soil microorganisms convert unusable atmospheric nitrogen into nitrates that are used by plants in a process known as Nitrogen Fixation.
What does field capacity indicate?
Amount of minerals present in soil
Number of aggregates the make up a soil sample
Amount of moisture or water content held in soil after drainage
Number of microorganisms thriving in soil
Which is the most dominant soil quality indicator?
Particulate organic matter
Earthworms
Soil enzymes
Total organic carbon
Which component of soil has the highest percentage?
Organic matter
Mineral matter
Water
Air
