My students were wondering what the effect the hole in the ozone layer has on the environment. Does this have any effect on global warming? Thanks!
|231: ||My class & I have been talking about global
warming and the effects it has on our climate

this solve our global warming problem? What
would happen if all of a sudden all this carbon
dioxide were to escape? Any information on how
this process works and the effects on the

I am a middle school teacher. Today I did a lesson in which students determined what their weight would be on the other planets in our solar system. We used a formula I found on the internet in another teacher's lesson Plan; the formula is: Mass (weight on earth) x gravity (different for each planet) = weight on that planet.
The gravity chart I used looked like this:
Our Moon 0.17
My students quickly filled in the chart and discovered how heavy they would be on Jupiter, how light they'd be on our Moon, and Pluto, and Mars and Mercury. Since they finished so quickly I asked them to find their Planetary Average Weight. We decided to throw out the Moon (not a planet) and Pluto (not a real planet anymore.) We found that every single student had an average planetary weight that was within one pound of their weight on Earth! I was in awe of this "co-incidence." I tried more weights, and the result was always the same: 8 planets, total weight on each, divided by eight ALWAYS equals Earth weight. So here are my questions: What makes this true every time?
Is the fact that this is true the reason that Earth is just right for life?
Does our home planet have that magic gravity amount that is exactly the solar system average?
Do the planets acting together add up to the perfect gravity environment for Earth? Or does this formula have other implications?
I am very interested to know your response. Thank you very much.

Maybe you could answer this question that has bothered me since I was at school.
If I stood on some scales situated on the exact North or South pole, would I weigh the same or less than if I were standing on the equator? Bearing in mind that centrifugal force would be acting on me on the equator but that the mass of planet beneath my feet would be more, which I believe means that the gravity here would be stronger!

I understand that after Ozone is broken down from the energy radiating into the atmosphere, O2 and atomic oxygen are produced. The O2 then eventually repairs with another atomic oxygen to form more Ozone. However, the presence of Chlorofluorocarbons apparently destroys the Ozone layer. When I looked at the reaction of the decomposition of Chlorofluorocarbons, I found that it was CF2Cl2 <--> CF2Cl + Cl, the atomic Chlorine pairs with an Ozone molecule, creating ClO3. This breaks down further into CLO and O2.
My question is, even if the chlorofluorocarbons are present in the atmosphere, it still provides O2 for more Ozone to be created. So, why is it a problem?
|287: ||Hi. |
What is the pressure at the center of a planet? For example, the pressure at 3 foot depth measured from the earth's surface under rock would be approximately 2.5 pounds per square inch.
It is commonly accepted that the gravity at the planet center is zero, equal mass pulling on either side cancels out in the middle. If an object at the center has no weight, then it cannot push on an adjacent object, so there should be no pressure exerted.
I believe the pressure distribution curve looks like half a cycle of a sine wave, the part above the horizontal line on the graph, with the depth being the horizontal axis and the left side being the surface, peaking somewhere around 1/2 or 2/3 the radius, dropping to zero at the center.
Most accounts claim high pressures and temperatures at the planet center, with the pressure causing the high temperature. I theorize the temperatures are high not because of pressure, but because the planets still have not cooled off after being created.
I am not looking for a numerical answer, just an explanation of how the pressure can be anything but zero in a zero gravity field. An assumption I have made is the planet is basically a pile of gravel held together by it's own gravity, not a prestressed structure similar in construction to a prestressed concrete beam, where there would be stress in the middle regardless of gravity. Most accounts claim planets form from the aggregation of material so assume no pre-stressing elements in the construction of a planet. thanks,

|300: ||Hi! When I read or hear about asteroids, specifically about those that have impacted the earth at sometime in the past, I notice that the authors compare the force that the asteroid impacted the earth with to the strength of the atomic bomb. (Example: The asteroid that killed the dinosaurs impacted the earth with the force of several atomic bombs) Now I know to calculate the force of an object that would hit the earth (f=ma) (correct me if that is not how you calculate the force of an object that would impact earth - must I know the objects speed, etc?) but how do I compare that force to the explosion of an atomic bomb? It would be interesting to see, for example, How the impact of a 10-ton object made of a various material, and the destruction that such an object would produce,would compare to the destruction of an atomic bomb. I would assume that 1 atomic bomb would produce the kind of destruction seen in Japan during WW2? Thank you so much for your help, Happy New Year!

We find a lot of fossils today and I have heard
it is because there were different events that
caused animals and dinosaurs to die. Why didn't
the fallen bodies of the dead animals just rot?
Why did they turn into fossils if they just fell
down dead? If all of those dead animals that
are fossilized were buried rapidly with water,
etc., (which is needed for the fossilization
process) what caused that to happen with all of
the thousands upon thousands of fossilized
creatures? Was it thousands of small disasters
with water, etc? I'm just confused on that
subject because we find so many different fossils
in so many layers.

which is why a plane traveling say 300 miles per
hour can fly and get some where, even though the
earth is revolving at about 1000 miles per hour at
the Equator. So, relative to the earth we are only
traveling 300 miles per hour. That is also the

Sea and what they found could offer a viable
scientific reason behind the Bermuda Triangle
phenomenon. 'Multiple giant craters exist on the

blowouts of gas,' researchers told the Sunday
Times. The craters in question were a half a mile
wide and 150 feet deep, the Daily Mail reports.

NGSS topic for 8th grade). I have been searching
for interesting tidbits in this area (fossil and
evolutionary finds, geological formations, etc).
Can you point me to documents or share info that
my students might find interesting? Thanks. |

|1209: ||If we haven't visited Jupiter then how do we know
that it is called Jupiter? If there was an
asteroid or comet that did hit Jupiter, how will
we know if we weren't there? If Jupiter has 67
moons but one of their moons is considered a dead
planet which is Callisto, can Callisto wake up and
become a real planet? |

the city gets floods every year? Is the city
really sinking? |

|1212: ||Why was the idea of Pangaea not accepted in the
first place? |
|1213: ||Can gems that miners find on the surface of the
earth be found deep into the ocean? If yes, are
they the same? |
|1214: ||Does plant life stimulate island growth? Over a
long period if the island only had coconut trees
would it slowly expand the soil of the island that
would make it increase in size? Say over 100
Years, 300 Years and 1000 Years. |
|1215: ||Why was hurricane Katrina so destructive to New
|1216: ||This supposed period of time when "Gondwana" or when all the continents were connected, explain to me how all these gigantic pieces of land moved if they are all stilled connected and surrounded by the earth\'s crust under the ocean? Where did all that mess of land go? And wouldn't the crust push against itself while the land masses went in opposite directions? |
|1217: ||Could you please refer to me a chart of gases in the stratosphere? The question comes from this observation: if the troposphere is comprised of 78% Nitrogen, 21% Oxygen, .09% Argon, along with other trace gases, what are the relative percentages for gases in the stratosphere considering that Ozone is most prominent in the stratosphere? Would seem that percentage of Nitrogen, Oxygen, etc., would be decreased by presence of more Ozone? Have searched wide for the answer. Hope you can help. Thank you. |
|1218: ||What is the probability for Mount St. Helens to explode again? |
|1219: ||How old is the earth? |
|1220: ||Why do we feel as if we weight the same on Venus as we do on Earth? Do we weight the same in both places? |
|1221: ||So if a tsunami and tidal waves are two different things (Tidal Waves are created by the gravitation forces of the sun or the moon, a tsunami is a series of water waves caused by the displacement of large bodies of water.) Then, why do you say that the difference between a hurricane and tsunami is that a tsunami is a huge tidal wave in the ocean? |
|1222: ||Why does the Earth have different layers? |
|1223: ||Why is there no air in space? |

|1225: ||What layer of the earth is the densest? |
|1226: || I am looking into questions about science I have had for a while which deal with Old Earth Theory. I was wondering if you could explain how scientists derived the half life formulas for radio isotopic decay, how it works, and how they know that other factors (temperature, geological patterns, weather patterns, other radiation present such as ultraviolet rays) have not affected their data. Is there anything known to the science community that affects the validity of different dating methods like Rb-87/St-87 dating, Argon-Argon dating, and Carbon dating? Thank you for your time. |
|1227: ||Ways in which weather affect our daily lives. |
|1228: ||What would life be like if the earth was covered with water and humans survived? |
|1229: ||In an estuary, does the fresh water float over the salt water? If so, why is it that the water in the estuary tastes salty? would you not be tasting the water that is on top and therefore the fresh water? |

|1238: ||I'm doing a debate for Science and it is about the difference between the lithosphere and the asthenosphere. Can you help me? |
|1239: ||Is the earth core a solid or something other then that? Is the mantle the layer that crates magnetic fields?
|1240: ||Why do Earth have layers? |
|1241: ||What would happen if we drilled a hole through the north and South Pole and dropped a rock into the hole? Where would the rock go? Where would it stop? How would it stop? Why would is stop/not stop? |

|1243: ||I wonder, how are waves in the ocean made? |
|1244: || Is there anyway we can prevent climate change from getting worse? |
|1245: ||Why do we get the most fog in the months of June and July, when December and January are the months of year where there is the most moisture/humidity in the air? (And rainfall) |
|1246: ||What type of minerals are formed to make emeralds? |
|1247: ||If the earth's core provides heat that drives plate tectonics, what would eventually happen if the earth's core cooled down? |
