Carbon Dioxide Greenhouse Effect
1,080 words
While some people believe the earth's climatic
changes are due to the fact that the universe is
getting older, others believe it is due to the
greenhouse effect. The greenhouse effect is a
naturally occuring phenomenon that is responsible
for trapping heat near the earth's surface and
keeping the planet warm. It is called the
greenhouse effect because the way it works is
similar to the way in which a green house
functions. In a greenhouse sunlight passes through
the transparent roof and walls an...

... locked into the melted minerals. If volcanic
rocks erupt on the earth's crust, such as the
Andean volcanoes, then magma can interact with
carbonate rocks such as chalk as it travels up
through the mantle or lower crust, picking up
carbon dioxide on the way. In subduction zones,
where the ocean floor goes down into the mantle
some carbonate rocks do get taken down and melted,
recycling their carbon dioxide content, but this
is a minor source compared with the mantle. Carbon
is quite common de...

How long can the environment endure the gradual
deterioration that is increasingly instigated
through car pollution? There is a tremendous
environmental impact on our society that impacts
us in the most unpredicted ways, and Im going to
share some suitable alternatives with you. Todays
technology has presented several alternatives that
could potentially decrease the amount of car
pollution in the environment; however, humans
seemingly neglect these alternatives in favor of
convenience and comfor...

Effects Of Acid Rain Sulfur Dioxide

"Acid Rain, " or more precisely acidic
precipitation, is the term used to describe
rainfall that has a pH level of less than 5. 6 --
a pH of 7 being neutral. This form of air
pollution is currently a subject of great
controversy because of the damage it does tot he
environment and property worldwide. For the last
ten years, this occurrence has brought destruction
to thousands of lakes and streams in the United
States, Canada, and parts of Europe. It also leads
to the deterioration of buildings a...

Ph Of 5 Sulphur Dioxide
1,087 words
Acidity is measured using a pH scale, with the
number 7 being neutral. A substance with a pH
value of less than 7 is acidic, while one of a
value greater than 7 is basic. A substance with a
pH of 6 is 10 times more acidic than another with
a pH of 7. Usually the pH of 5. 6 has been used as
the baseline in identifying acid rain, although
there has been much debate over the acceptance of
this value. Interestingly enough, a pH of 5. 6 is
the pH value of carbon dioxide in equilibrium with
distilled ...

By the middle of the twenty first century, there
is evidence that the Earth will be warmer than it
has been at any time in human history, and quite
possibly since the end of the dinosaurs, some 65
billion years ago. If we stay at the rate we our
now (fossil fuel consumption / growth in
population) then within the next two century the
Earth's air might not be fit to breath. Many
people in the world do not think that this is a
major concern and that it is normal for the
Earth's temperature to incr...

Air Pollution Air pollution is one of the most
dangerous problems of our times. Problems caused
by pollution can be local and minor because of the
Earth's own ability to absorb pollutants. The
industrialization of society, the introduction of
motorized vehicles, the explosion of the
population are factors sharpening the growing air
pollution problem. Carbon monoxide, nitrogen
oxides and particulate matter belong to pollutants
found in most urban areas. These pollutants are
dispersed throughout t...

The Exhaust Systems Exhaust Systems The exhaust
system on a car is the most important device to
keep our environment clean. Many exhaust emissions
from the engine such as water, oxygen, nitrogen,
and carbon dioxide, are of little concern. Others,
such as hydrocarbons (HC), oxides of nitrogen
(NO), and carbon monoxide (CO), can cause
environmental and health problems if not
controlled. Hydrocarbon emissions react with
sunlight, which cause photochemical smog. The
exhaust system controls these the...

Global Climate Change Climate change is not a new
concept; in fact there is evidence of major
climate changes throughout the earths history.
However since the industrial revolution and
especially since world war two, there has been an
unprecedented change in the earths atmosphere
(Gates 4). As of March 1999, scientists reported
the construction of a thousand-year record of the
average temperature on earth. The results of their
study concluded that a nine hundred-year cooling

There is little doubt that the airs carbon dioxide
concentrations have been increasing since the
Industrial Revolution and there are few who do not
attribute this increase to the rise in humanity's
use of fossil fuels. There is also little dispute
that the earth has warmed slightly over the same
period. During our interview Adam told me that he
believes strongly in the dangers of global warming
and feels great animosity towards critics of this
theory. Our conversation had an angry tone as Adam

Methane Nitrous Oxide Carbon Dioxide

The greenhouse effect is an increase in the
atmospheric temperature caused by increasing
amounts of greenhouse gases. These gases act as a
heat blanket insulating the Earths surface
absorbing and trapping heat radiation which
normally escapes from the earth. They include
carbon dioxide, water vapor, methane, nitrous
oxide, CFCs, and other halocarbons. The earths
atmosphere goes through two processes constantly.
Global cooling is the first process. This process
uses the clouds which cover 60 % of...

March 19 Historically, the term smog referred to a
mixture of smoke and fog, hence the name smog. The
industrial revolution has been the central cause
for the increase in pollutants in the atmosphere
over the last three centuries. Before 1950, the
majority of this pollution was created from the
burning of coal for energy generation, space
heating, cooking, and transportation. Under the

Photosynthesis is a very important process in
nature. It is the production of energy in the form
of glucose involving water from the soil, carbon
dioxide from the air and light energy. It takes
place in all green plants, which use the green
chlorophyll, held in chloroplasts in the leaves,
to trap light. The main site of photosynthesis is
the palisade mesophyll cells in the leaf of a
plant. It is these cells that contain the green
chloroplasts and are very well adapted to their
task. They are nea...

Space: Pollution is a Global Responsibility The
statement says that pollution is a global
responsibility, but first of all, in order to
understand the statement and therefore argue the
points of view, we must state what can be defined
as Pollution. The Oxford dictionary states that to
pollute an area is to Destroy the purity or
sanctity of; make foul or filthy; contaminate or
defile There are many types of pollution that

also on the microcosmic s...

Global warming is a very serious problem plaguing
our world. Global warming is defined as a warming
of the Earths surface and lower atmosphere that
tends to intensify with an increase in atmospheric

exactly what it sounds like; the warming of the
Earths temperature. There are many explanations
and theories about why global warming is occurring
in our world. The atmosphere lets in heat that
