Earth Then and Now (1)

The planet Earth is a sphere comprised of layers, or shells, similar to an onion. The upper shell is the crust, on the surface of which the life as we know it thrives. Below the crust the upper and lower mantle shell. The mantle is ,a molten matter that produces volcanic lava. The mantle extends down to the core of the planet Earth. The upper shell of the core is a less viscous fluid; it does not flow as quickly as the mantle liquid. The lower part of the core is a solid sphere made primarily of iron, with a lesser amount of other elements. The solid sphere in the center of the earth produces the magnetic field that serves as a protective shield above the planet.

The planet Earth has, in the past, experienced violent break-up which impacted the crust of the planet more than the lower layers of the planet Earth. Because of the violent break-up, it is not possible now to ascertain the Earth’s original characteristics accurately. The current crust of the planet Earth varies in thickness from approximately three (3) miles (or about 4.8 kilometers) to nearly forty-four (44) miles (or approximately 70 kilometers). The bottom of the crust is the sub-oceanic part of the crust which is more uniform in thickness.

The planet Earth in its current configuration has several large and several smaller plates called “tectonic plates.” Tectonic plates are in constant motion which causes earthquakes. Deep sub-oceanic cracks or tranches now surround the Pacific Ocean. These tranches are the source of the majority of earthquakes that occur on the planet Earth. Violent upheaval created the majority of the current mountains on the Earth.

The Creator, at the end of the creation narrative, declared the Earth to be “good.” However, even without the biblical narrative, we could conclude that the current configuration of the planet is not so good, it is not exactly the way it came out of the hands of the Creator. What was the original condition of the Earth? The answer is in the next Blog.
