many of the substances found in the earth are also found in other planets. what are this substances?

I believe all the naturally occurring elements found on earth can be found on other planets, for example samples from the surface of mars show that it is composed of basalt and granite, these are igneous rocks (come from volcanoes) that are very common on earth. Elements like iron, silicon, carbon, and  hyrogen are found in a variety of forms

Carbon, Iron and Nickle. In that order I believe. \n\nThat is of the earth itself... If you mean of the planet including the atmosphere, then its Hydrogen and Helium.

A terrestrial planet or telluric planet is a planet which is primarily composed of silicate rocks. The term is derived from the Latin word for Earth, "Terra", so an alternate definition would be that these are planets which are, in some notable fashion, "Earth-like". Terrestrial planets are substantially different from gas giants, which may not have solid surfaces and are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. \n\nThe four innermost planets of the solar system, resembling the Earth in general physical and chemical properties.

Yes, I do believe that life does exist in the universe on other planets. its doesnt mean that life is there only on Earth n in our solar system of the STAR SUN.\nIf u c there r millions of stars in the universe and triliions of planets so there is a possibility to find a planet similar or exact as EARTH which has the same atmosphere or maybe the same gravitational field or perhaps the same solar system is repeated somewhere in the universe.

Everything around us is a chemical. That is all foods, all fibers, natural materials in the environment as well as the man made materials.

We have already found planets orbiting other stars in our solar system. They detect them by the "wobble" of the star. The wobble tells them something is orbiting the star. Knowing the stars aproximate mass, they can tell roughly how big the planet is. We have found almost one hundred planets outside of our solar system.

In our Solar System, there are eight official planets, nine if you count Pluto (whose status is being debated).  \n\nAs for the rest of the universe, it is difficult to say, but it is reasonable to assume that planet formation from leftover stellar material is relatively common.  Astronomers usually detect large gaseous planets (like Jupiter) by the slight wobble of the star's motion due to the gravity of the planet, so currently it is almost impossible to detect small planets.\n\nAs of November 2005, there were 164 confirmed extrasolar planets.

If I remember my chemistry correctly, an organic molecule is one containing carbon and at least one other element.  So, a non-organic substance would be anything else.

Yes, we will discover other planets that also sustain life, and we will do so within our lifetime.  I do not mean that we will physically go to these planets but we will discover this by placing much more powerful telescopes in orbit around Earth.  There is a definite signature that we will be looking for and that will be the presence of Oxygen in another planet's atmosphere.  If a planet does not have any oxygen in its atmosphere then it would not be able to support life.  There was a time billions of years ago on Earth when there was no oxygen in the atmosphere and at that time there was no life on Earth.  We may not discover other intelligent life on other planet's during our lifetime but i am sure that we will discover other planets that are supporting at least plant life if not primordial single cell life as well.

That'd be Astatine, there's about 25g of naturally occurring Astatine on the planet only.

The first four\nMercury, Venus, Earth & Mars\nand the last one\nPluto\n\nAll other planets are considered "gas planets"

In the Solar System Venus and Mars among the planets, the Moon and possibly some of the outer planets satellites such as Ganymede, Triton and even strange little Pluto/Charon maybe very similar to Earth being that all the planets formed from the same cloud of dust, gas and other space debris at the same time around 4.6 billion years ago.

It depends on if you are looking at large quanities or just any ammount goes. It also depends on if you are looking at elements that are only found in compounds or not. Oxygen, hydrogen, argon, carbon, nitrogen, alluminium, silicon, iron, tugstan, lithium, potassum, titanium to name a few. almost all of the elements can be found near the earth's surface except those that are man made, usually the extremly heavy ones like plutonium.

Most of the earth Surface is Covered with water, but that's only a small fraction of the planet itself. The Earth is made up mostly of silicate and magezeuim compunds and an iron core.

The Earth is the most important planet in the Universe.  It's the most important one because it's the one I live on and own real estate on.  If I lived on a different planet, that other planet would be the most important planet in the Universe.

water, the oxygen and the abundant food. these are basic things that human being need on the earth.so all these can be found on the earth..water from rivers.oxygen from the air and food from fruit/trees, animals etc etc.
