This is the thread to study more about our planet. Perhaps you are a expert or have alot of knowledge in it. If so then don't hesitate to share your knowledge for others to learn about it.

Here is a introductory:

Geology is the study of Earth.

Geology studies the composition of Earth and all of the elements and materials that make it up. The structure of the Earth, including plate techtonics, the different layers of the Earth and the atmosphere are all part of biology.

Geology is also one of the only sciences that deals with the history and formation of the planet. G

Geologists help locate many of Earth's natural resources in the form of metals, gems, minerals, and elements including quartz, sulfur, gold, petroleum, coal, iron, and helium.

There are a few principles important to geological studies. The principle of intrusive relationships shows the mixes of young and old rock which allow geologists to understand the happenings there.

Faults allow geologists to understand how the plates of Earth's crust move. The principle of uniformitarianism states that the same geological processes occur throughout history. This means that geologists can study what happened to Earth in the past by observing what is happening now. Younger layers of rock can slip between older layers, layers are basically horizontal, and fossils found in different layers of rock can give information about the life at that time.

Here are some interesting facts:

There are four layers that make up the Earth: the inner core, the outer core, the mantle, and the crust.

It only snows about 2 inches per year over most of Antarctica.

The largest desert on Earth is on the Antarctic continent.

90% of all volcanic activity occurs in the Earth's oceans.

The deepest point in the ocean is 6.8 miles down.

In polar areas in mid-summer, there is no night -- daylight lasts almost 24 hours a day.


Perhaps you have some unusual information to share. If so then please do!

LOL. Nobody is going to read this! Might as well make it fun!!.

Why didn't gold and lead and uranium and all that other heavy stuff sink when everything was molten? Why is our Moon so big?

Current thinking is that a planet about the size of Mars crashed into early Earth several billions of years ago. The velocity and angle of the strike was just right to spin the Earth and tear off a huge blob of planetary matter that condensed into the Moon. Earth, as Elvis would say, was "All shook up!, and core materials were mixed with mantle and crust materials. The subsequent cooling and solidification of the mix gave us a new Earth. Many metals formed oxides which were not much different from the silica minerals around. Some metals, like gold, simply won't combine with much and sat there all shiny. Volcanic activity and plate tectonics mixed and churned the crust to give us what we see.

Yes I have heard that before also. That the moon is actually a chunk of the Earth.

yet could it be possible that the moon was always the moon. I say this for it is told that when a sun explodes material, dust, gases, radiations, etc. etc. forms and eventually creates planets and moons. Could that be another possiblity?

I mean now we have to ask ourselves how where the planets formed. I think it has something to do with a explosion that is for sure.

First of all, all of our solid material was created in supernova. The explosion creates a gas/dust cloud that eventually condenses to small objects which can later fuse into larger objects. Our moon is too big to have condensed along with earth. The "hit by Mars size planet" is the only theory that fits the facts as we know them. However, all the solid elements were indeed created in the explosion of a star with the major exception of hydrogen. Helium if formed in stars without the necessity for them exploding but if our helium was formed in a star that didn't explode, it would still be there.

The moon would not technically be a "chunk of Earth". When the two planets collided, a new mix of material would be created and the moon and earth would both be some of the original earth and the "Planet X" It may be more or less the original earth or more or less the rogue planet.

I see. Now I understand. Very interesting indeed.
