How to minimise the negative side effects and their impact on Earth of burning fossil fuels?
Burning fossil fuels contain radioactive materials which are released into the atmosphere. Also, burning fossil fuels generate sulphuric, carbonic and nitric acid which falls on earth as acid rain so how do we minimise this?
Answer:
switch to renewable resources
use less energy when possible
walk ride a bike or take public transportation
contact your elected officials and try to promote legislation that will minimize the damage of burning fossil fuels
How to test whether the core of another planet is completely solid?
Set off a bomb to create seismic waves. If P waves arrive on the opposite side of the planet, then the core is solid.
Set off a bomb to create seismic waves. If S waves arrive on the opposite side of the planet, then the core is solid.
Set off a bomb to create seismic waves. If R waves arrive on the opposite side of the planet, then the core is solid.
Set off a bomb to create seismic waves. If L waves arrive on the opposite side of the planet, then the core is solid.
Answer:
Set off a bomb to create seismic waves. If S waves arrive on the opposite side of the planet, then the core is solid.
S (shear) waves will not travel through liquid.
But there are other easier ways to test whether a planet has a liquid core. For example if the planet has a significant magnetic field, then it must have a liquid core. Mercury for example has a magnetic field and therefore a liquid core - whereas Mars does not have a significant magnetic field and therefore is predicted to be entirely solid. There are also subtle clues in the way a planet rotates - see the links for details.
How to justify earthquakes are better than tornadoes?
Thanks Alex but what I meant was in the US.
Answer:
Tornadoes occur more frequently than do earthquakes, at least those that cause physical harm to people. Tornadoes are also more unpredictable than earthquakes are. For example, throughout the Midwest each Spring, a number of severe thunderstorms are certain to occur any of which could spawn a tornado or tornadoes. Where and when one might strike is not known.
Generally speaking, we expect the majority of earthquakes to be very localized. Most will occur either along the San Andreas fault zone or the Hayward fault zone in California. For years building codes have been strengthen in these areas so that structures could better withstand the force of an earthquake. We don't expect the same damage or loss of life as the 1906 SF quake or the 1971 San Fernando quake.
Having experienced a number of earthquakes and tornadoes, I would say I felt more helpless during a tornado than I did during any of the dozen or so earthquakes I felt.
How to find out if there are ore deposits on your property?
I thought it would be kind of cool to try to do some mining, how can I see if I have ore on my property and possibly what kind it is?
Answer:
Mining huh. You must have a very large piece of property, or a lot of money that you are looking to throw away. By the way, just because you may live above a copper deposit doesn't mean that you have ownership of said copper deposit. Unless mineral rights were conveyed in the purchase of the property there is a very good chance that somebody else owns the subsurface minerals.
But to answer you question, I would say the first step is to find a geologist experienced in the search for subsurface minerals and see if they find any potential for there being copper deposits based upon the geologic history of the area.
How to observe waterfall features of erosion and deposition?
Its a geography investigation and am really stuck, thanks . The aim of the investigation is to observe features of erosion transporation and deposition that may have been responsable for the development of a waterfall. My geography teacher wont help me !!!
Answer:
You should begin with charting the carbon based constiuents of the primary limestone that you are observing. Biological weathering is a process of rock and mineral disintegration caused by physical and chemical agents of living organisms. Whether weathering is caused by bacteria or a plant or an animal, it may have both physical and chemical effects on the surface. These effects include breaking of particles, movement and mixing of materials, production of carbon dioxide by breathing and a biological process of chelation (production of organic substances). Organisms also have an effect on the pH of the soil.
Recognize any levels of patena growth. These organisms will utilize the process of chelation. Calculate the Limestone Chemical Composition
The chemical composition of the different varieties is almost the same, and it may therefore be given at once for the whole.
The following is the analysis made by Professors Daniel and Wheatstone for the commissioners who selected the stone for the Houses of Parliament: -
Silica ......
1.20
Carbonate of lime ....
9516
Carbonate of magnesia ....
120
Iron and alumina ....
0.50
Water and loss .....
1.94
Bitumen .....
A trace.
These rates should be in your text book or in a handout. Look through your notes. Given this information you should be able to complete your paper.
How to people distinguish metals from different mines?
For example, a person is studying the Archaeometallurgy of copper and there are two samples of copper artifacts. Both artifacts are similar in design, so how do they distinguish which copper came from which mine?
Answer:
They take a small sample and analyze it for trace elements.
For example gold bars are samples after they are refined at a mine mill.
The sample is taken by drilling a small hole and saving the drill cuttings.
The combination of other chemical traces still in the gold are as distinctive as a fingerprints are with humans.
How to stop breaking wind so much?
I know it's disgusting and everyone does it, but is there any remedies/treatment or high street products to stop doing it soo much?
Thanks

... and for some reason you think Geologists are likely to have the answer to this vexed question...?
Are Geologists renowned for their abilities to cure excessive flatulence?
How to convert from air permeabilities given by core analysis to brine permeability? I?
I have a set of air permeabilities which I want to correct to brine permeabilities, how I can do that? Is there any equation to do it? What parameter do I need to do this correction?
Answer:
poseuille flow eqn for liquid trav in fine tube (I assume porous rock can be approx to set of microbores!?) is..
q=pi*r^4(P2-P1)/(8*u*L)..u=viscosity of (incompressible fluid), P,L,etc usual meanings
for a gas its q=pi*r^4(P2^2-P1^2)/(16*u'*L*P1)..u' =gas vicosity
ie same equn with correction factor of k=1/2(P2/P1+1) and using u'(gas) applied
ur permeabilty eqn for a gas thru rock sample doesn't look rite..viz
q=k*pi*r^2*(P2-P1)/c*L..c='mobility'.. unless flo-r8 is v small..or correction factor already applied
best suggestion..since u(air)=abt 1.8E-5Ps..and u(water)=1E-5Ps (@ NTP
decrease ur permeability coeff by ratio u(water)/u(air)..ie divide by 1.8!
