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.

COMPARISON BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY

COMPARISON   BETWEEN SCHLUMBERGER ARRAY OVER WENNER ARRAY Find below the pros and cons of Schlumberger Array over Wenner Array and vice versa Are you a young geologist? Click HERE NOW!!! Advantages of using Schlumberger Array over Wenner                 It requires less manpower and time than Wenner soundings.                 It is less sensitive to lateral variations in resistivity. The potential electrodes are moved only occasionally; In a Wenner sounding the potential and the current electrodes are always moved after each measurement. It is faster in field operation. Types of VES Curves Requires less physical movement of electrodes than the normal Wenner array because only the current electrodes must be moved between readings. The effects of near surface, lateral inhomoge...

CAUSES OF WATER BOREHOLE FAILURES IN NIGERIA

HAVE YOU HEARD ABOUT OIL SHALES BEFORE?? Water is one of the most (if not the most) essential requirements for life existence on earth. It is a well known fact that the human body is made up of about 75% water. Apart from water for drinking, it is relied on for industrial and domestic chores. It is available in the surface and sub-surface. But the surface water is usually not enough and in most cases not available all year round due to seasonal variations namely: Rainy and Dry Seasons . During the Rainy Season, the Surface water becomes readily available (though may or may not be enough depending on the need) but the contrast is the case during Dry Season. Hence the resort to Boreholes . Let’s start by defining a Borehole. In the simplest term, as the name implies: Bore Hole.  It means to ‘ bore a hole’ ; or simply put: ‘to drill a hole’, ‘to sink a hole’, ‘to punch a hole’ on the ground to create a cavity inside the ground where water can accumulate, be sto...

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.
