The overall condition of the Australian marine environment is good, but integrated management will be key to the future conservation of our ocean resources. The rate at which the physical environment of the region is changing appears to be faster than the rate at which organisms, especially those of a higher order, can adapt to the changes
ISC Exam Notes : Content: Ozone Layer Depletion
http://iscexamnotes-content.blogspot.com/2010/04/ozone-layer-depletion.htmlThe key observation is that, ordinarily, most of the chlorine in the stratosphere resides in stable "reservoir" compounds, primarily hydrochloric acid (HCl) and chlorine nitrate (ClONO2). During the Antarctic winter and spring, however, reactions on the surface of the polar stratospheric cloud particles convert these "reservoir" compounds into reactive free radicals (Cl and ClO)
To lament that ozone depletion is taking away "our protection" is the same as crying that surfers are wearing down the surf, and as the surf is all there is holding back the ocean, when the surf goes (due to human behavior) the water will flood over the land and destroy mankind. Faced with this rather unfortunate logic, some researchers extend the plot, claiming that in the upper atmosphere the intense UV light is sufficient to break down the CFCs, releasing chlorine which then does the damage
(An analogous situation is watching rain fall from a moving train - although a raindrop is falling straight to the ground, it will appear to fall at a slant, and the slant increases as the train's speed increases.) The aberration of light is due to the fact that light travels at a finite speed (as do the raindrops). ATEN ASTEROIDAtens are asteroids that are always closer to the Sun than the Earth is; they have a period shorter than 1 year (the semi-major axis is smaller than Earth's)

Energy transfer in the atmosphere and oceans
What is the Atmosphere? Surrounds the Earth made up of layers of gases Argon , Oxygen , Nitrogen Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere Different temperatures 3. A circular current in air and other fluids caused by the rising of warm fluid as cold fluid sinks Convection currents are one of the main way that energy is transferred in the atmosphere

How can you ignore the thousands of other scientist's that contradict global warming theories? If carbon dioxide was truly a pollution, we would not be here on earth. Could you put some more about the mesosphere? please and thank you 3 LeahSep 21, 2010 @ 3:15 pmWhat layer is the northern lights located in? the troposphere, the stratosphere, the mesosphere, or the thermosphere 4 justinOct 19, 2011 @ 3:15 pmthis passage shows very informational details about the layers of the atmoshere
Atmosphere definition of atmosphere in the Free Online Encyclopedia
; global warming global warming,the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. In addition to this, the general circulation implements the hydrologic cycle in the atmosphere, carrying water vapor from the oceans to the dry land and providing moisture for the continents
Aurora Borealis or Northern Lights
These forecasts predict the most active locations for the aurora borealis for a specific time and give a range showing the strength of auroral activity. Maximum auroral activity is rare however and the aurora borealis is normally only seen in or near the Arctic Circle in places like Alaska, Canada and Norway.In addition to the aurora borealis in the northern hemisphere there is also the aurora australis, sometimes called the Southern Lights, in the southern hemisphere

The Ozone Hole Questions and Answers About the Ozone Layer
Ground-based instruments with excellent long-term stability and accuracy are now routinely used to help calibrate space-based observations of total ozone. Emitted gas molecules with atmospheric lifetimes greater than a few years circulate between the troposphere and stratosphere multiple times, on average, before conversion occurs
Layers of Earth's Atmosphere - Windows to the Universe
So, the more active the Sun, the thicker the ionosphere! This image shows how different types of solar radiation (x-rays to infrared radiation) penetrate into the Earth's atmosphere. Due to increases in gases, like carbon dioxide, that trap heat being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance creating the greenhouse effect
How does the aurora borealis (the Northern Lights) work? - HowStuffWorks
The auroras, both surrounding the north magnetic pole (aurora borealis) and south magnetic pole (aurora australis) occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. The next peak will occur in 2011 and 2012, so opportunities to see auroras outside their normal range should be good.For more information on auroras, check out the links on the next page

Why is the Sky Blue - Layers of the Atmosphere
Although the concentration of ozone is at most 12 parts per million (ppm), it is very effective at absorbing the harmful ultraviolet (UV) rays of the sun and protecting life on Earth. The Magnetosphere is the upper part of the ionosphere, extending out to 64,000 km (40,000 miles.) It protects us from the high energy, electrically charged particles of the solar wind, which are trapped by the Earth's magnetic field
