HOW WAS THE EARTH FORMED


HOW THE EARTH FORMED

If you are reading this post now which I know you are, then you are among the inquisitive peeps out there. The Earth was formed oneday just as you were.



This has been an issue all the while even outside the science domain. This led the scientists to delve into it.

I advice you fasten your seat belt as I take you through this in a few moment.

There is this theory called core accretion - Have you heard of this before?
Well, core accretion is the increase in the size of the earth by the coming together of dusts and meteoric substances from the space. This is Big-Bang theory.
Way back before the Earth was formed, the entire system (i.e. solar system) was a cloud of thick dust. These dusts later began to spin and come together. This coming together is called accretion. The heavy (rocky) materials formed the Earth while the lighter materials like hydrogen and helium formed the gaseous planets like Jupiter and the rest of other gaseous planets. The separation of the heavy materials and the lighter ones was brought about by the solar wind and gravity.
Within the Earth, the heavy materials sank down (under gravity) giving rise to the mantle while the lighter materials settled on top – forming the Crust.

The Earth suffered a major impact in the time of its formation. This led to fragments of the mantle being thrown into the space. These particles aggregated under gravity and formed the moon. - Now you know why the moon orbits round the Earth?... because it was formed from the Earth … and may be saying to the Earth “Even though you birthed me, I can’t let you go. I will always be around you forever”

Collisions within the mantle and the core (plumes) gave rise to the mountains and volcanoes evident in different parts of the Earth today. During these collisions, the gases sublimed into the Atmosphere.

THE AGE OF THE EARTH - THE OLDEST MAN ON EARTH IS THE EARTH

THE AGE OF THE EARTH Hey … Just as we celebrate our birthdays to commemorate the day we were born, has it ever occurred to you to ponder on the age of the earth? Don’t you think that there was a day (way back) when the earth was formed? Don’t get it twisted!!! This is no myth. It is a reality. It is REAL!!! The Earth is approximately 4.6 billion years old!!! Sounds absurd??? Well, this figure did not come as a result of fiction or imagination – but by radiometric dating in the early 20 th century. Lead in uranium-rich minerals when dated by early scientists,  were able to discover that they were billions of years old. Another pointer to this is that small crystals of Zircon obtained from Jack Hills, Western Australia when dated, was around 4.4 billion years old. One may ask: “How is this possible”? Rocks are aggregate of minerals. Some of these minerals have radioactive elements like Uranium and Thorium. In the process of their decay (radioactive

Lead in Drinking / Groundwater

Possible sources of lead in groundwater Places well known for lead-zinc (Pb-zn) deposits are in danger of having their groundwater contaminated with Lead. Lead is a known silent killer especially in infants and children as it has high affinity for Hemoglobin. Another reason it is a silent killer is because it accumulates (bioaccumulation) in the body gradually stealthily. The fatality of lead is that it gets stored in the bones (as Calcium is stored) and becomes part of the body. From there, it gets released directly into the body. Pregnant and nursing women are the most hit because the Calcium which their bodies require for the growth of the fetus and for breast milk production may be mixed with Lead. The detrimental effects of lead are enormous and felt among infants / children, pregnant women and adults. Among the children , these (but not limited to the following) are pronounced: Ø   Anemia Ø   Slowed / stunted growth Ø   Poor body development Ø   Poor i

Vasquez Rocks

Have you heard of Vasquez Rock? Credit: The above picture will be alien except to those within the vicinity of Aqua Dulce, California or perhaps, those that have visited here at one time or the other. Just watch the arcs and the angles formed by this deposit!! In case you do not know, the image you are seeing is Vasquez Rocks. Am fascinated about the arcs and the acute angles formed by this deposit.. Your groundwater may be polluted!!! Nature is indeed wonderful!!!! For emphasis sake, this is in Aqua Dulce, California, north of Los Angeles. Research has it that the ‘arcs’ formed (i.e. tilting was as a result of the North American Plate collision with the Pacific Plate) along the San Andreas fault. We can see that the collision resulted in the uplift.
