Ground Water Acid Rain
1,021 words
Many people assume that water is an unlimited
natural resource. Is this true? Although water
appears abundant, recent circumstances indicate
that it is seriously vulnerable to pollution and
depletion. Throughout this essay we will examine
what ground water is, how it is important in the
water cycle, how its contamination can affect us,
and what we can do to protect our ground water
from contamination. Ground water is the water
found in spaces between soil particles and rocks,
within cracks of th...

Have you ever wondered why your plants in your
house and outside lean towards the sun. In my
project I hope to answer why this happens. I am
going to be using lima beans to do this with. The
Greek philosopher Aristotle may have been the
first to attempt to explain the processes of
photosynthesis and food production. He believed
that plants could obtain from the soil all the
components required for growth. The cycle was
completed when organisms perished and became
reincorporated into the soil. Th...

be elliptical with rounded tips. There are 7 to 25
leaflets per leaf and size increases towards the

World War Ii Environmental Impacts

Should we be concerned with the extensive use of
pesticides by farmers? I believe we should be
aware of the consequences of pesticide use. The
more we are exposed to pesticides, the greater the
risk there is to the environment and our health.
They are responsible for many environmental
problems such as water pollution, soil
degradation, and insect resistance. I will look at
all the environmental impacts caused by pesticide
use. But what led to the rise of the use of
pesticides? Tremendous increa...

Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 words
What is acid rain? Acid rain is the term for
pollution caused when sulfur and nitrogen dioxides
combine with atmospheric moisture. The term 'acid
rain' is slightly misleading, and would be more
accurate if deemed 'enhanced acid rain', as rain
occurs acidic naturally. Acidity is measured on
what is know as the pH scale. Fourteen is the most
basic, seven is the most neutral, and zero is the
most acidic. Pure rain has a pH level of 7, which
is exactly neutral. The acidity of rain is
determined by t...

Sulfur Dioxide And Nitrogen Burning Of Fossil Fuels
1,264 words
What is Acid Rain? Acid rain is a form of
precipitation that falls to the earth as rain. For
rain to be acidic it has a pH level of less than
5. 6. The corrosive nature of acid rain causes
widespread damage to the environment. The problem
begins with the production of sulfur dioxide and
nitrogen oxides from the burning of fossil fuels,
such as coal, natural gas, oil and other kinds of
manufacturing. When these pollutants are in the
air, they react with water and other chemicals, to
form sulfuric...

Earthquake Loads Resistant Design Of Buildings

... Spectra are developed by calculating the of
response a single mass oscillator (usually with 5
% critical damping present) to the design level
earthquake motion. Engineers traditionally have
shown a preference for acceleration spectra, since
the resulting coefficient, when multiplied by the
seismic mass, results in the lateral base shear
for the building. In Australia [ 7 ] and the
Uniformed Building Code used in the western USA [
9 ] these spectra are presented as a simple
uniform coefficien...

levels on Rhizobium bacteria, and can a pH
resistant Rhizobium culture be grown? Hypothesis
Alterations of the balanced habitat such as the
change of pH levels can drastically alter the life
of bacteria and can directly affect chemical
reactions of enzymes released by the bacteria.
Using this information the change in pH will have

find their way into coastal waters around the
