Earth Sciences & Geology - July 2007

It's said to be a perfect cone, but it has a caldera at the top two kilometers wide. It's mostly basalt, but not entirely solid because it's the product of many eruptions -- maybe more like compacted crushed basalt -- I'm not sure.

Please, if you can, include numbers and sources. Thanks.
---------------------

Below is one calculation a friend attempted. Is it close to accurate? If not, what's flawed? I can see, for one, that he's not taking the caldera into account.
----------------------
Mt. Fuji is made almost entirely of basalt. I figured out how much a cubic meter of solid basalt weighs (3011 kg/cu.M).

Mt. Fuji is 3,776 meters tall and about 11,300 meters across at the base.

I then figured out the volume of Mt. Fuji. (area of base * height)/3 or…126,224,799,813 cubic meters.

So the Basalt in Mt. Fuji weighs nearly 380,062,872,237 metric tonnes.

If you could put the earth on scales how much would it weigh and if everyone dieted at the same time would the earth weigh less?

I understand that the geologists are convinced that the earth is quite old, but I can not always understand their texts and films. Can anyone give a simple explanation?

my teacher said there are two reasons,
i guess the first one is because of the temperature, what is the other one?

Just a few years ago I remember reading that mankind had finally overtaken nature in the volume of rock and earth which is shifted each year. That is to say, using earth-movers etc we move more material around the planet than all the natural agencies such as rivers, glaciers, the wind, currents etc

Can anyone point me in the direction of an article on this? I haven't been able to find one yet - wrong search terms!?

Some of the natural causes of the global climate change are - plate tectonics, volcanic activity, and long-term variations in the earth's orbit and the angle of of its rotation axis.

1) Describe each of the natural causes of global climate and explain how can each affect the climate.
2) The climate affects described above occur over long periods of time. Present a scenario by which some natural phenomenon might catastrophically change the global climate on a much shorter time scale.

Thanks!

I am not science based please help. Simple language is best!

Looking at the periodic table what is it possible or not possible to 'extract?' using Phytoremediation on a brown field site.?


What is Phytoremediation?
Phytoremediation consists in depolluting contaminated soils, water or air with plants able to contain, degrade or eliminate metals, pesticides, solvents, explosives, crude oil and its derivatives, and various other contaminants, from the mediums that contain them. It is clean, efficient, inexpensive and non-environmentally disruptive, as opposed to processes that require excavation of soil (Source: Wikapedia).

Fossil fuel use, as well as producing greenhouse gases, creates other by-products. These by-products are also pollutants, such as sulphur dioxide, soot, and ash. These pollutants however, also change the properties of clouds.

Clouds are formed when water droplets are seeded by air-borne particles, such as pollen. Polluted air results in clouds with larger number of droplets than unpolluted clouds. This then makes those clouds more reflective. More of the sun’s heat and energy is therefore reflected back into space.

This reduction of heat reaching the earth is known as Global Dimming.

(1) Why do you blindly believe in science that is mixed with non-scientific truths?; (2) According to your world-view answer the following: (a) What is your value; (b) Where did you come from; (c) What will happen when you die; (3) How can a Big Bang come from nothing?; (4) If the Earth is millions or billions of years old - why isn't there a much larger desert in existence (than the Sahara)?; (5) IF the Earth is billions of years old - why hasn't the Gulf of Mexico been completely filled with mud? The Mississippi River deposits 80,000 tons of sediment an hour.; (6) IF the Earth is millions or billions of years old - why does oil still have pressure? It is held under pressure at 20,000 psi for approx 10,000 years. ; (7) IF Earth is billions of years old why doesn't the present population numbers reflect that amount of time?; (8) How can 'nothing' become hot liquid rock to primodial soup and become all known kinds of life on Earth?; (9) Why isn't matter evenly distributed?
