What’s under our feet? The Earth’s structure is a bit like an egg. Did you know?

The Earth‘s structure is a bit like an egg. Did you know? To be clear in our explanation of what cause “Climate Change” and what it’s have to do with us, we need to start with the real beginning: Planet Earth. Everything happen there and to grasp what is our challenge we need to know exactly what we are talking about.

Physical life start and finish here.

“In the very beginning of earth’s history, this planet was a giant, red hot, roiling, boiling sea of molten rock – a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth’s early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.

It is theorized that the true age of the earth is about* 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in – when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock – a magma ocean.

Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth’s surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age. Says Extreme Science.

Geophysics, which studies the physics of the Earth, has led to many significant discoveries about the Earth and its make-up. Seismologic studies of the Earth have uncovered new information about the interior of the Earth that has helped to give credence to plate tectonic theory.

The Earth’s structure is a bit like an egg:

  • The “yolk” at its center is an iron core thousands of miles across.
  • Around the core lies the mantle, a layer of super-hot rock thousands of miles thick. The mantle begins about 6 miles (10 km) below the oceanic crust and about 19 miles (30 km) below the continental crust (see The Crust). The function of the mantle is to separate the inner mantle and the outer mantle. It is about 1,800 miles(2,900 km) thick and makes up nearly 80 percent of the Earth’s total volume. Science deals with the structure of the mantle in two different ways. One way is based on its chemical construction (the material), the other on the way layers stream or move.
  • The outermost layer (the crust) varies in thickness from around 120 km (75 miles) under some continents to less than 3 km (2 miles) under some oceans. Like the broken shell of an egg, the Earth’s crust consists of a set of interlocking plates. These tectonic plates are all moving slowly relative to each other. The ground beneath our feet is not as solid and unchanging as it might appear. In fact, the earth’s surface (crust )consists of more than a dozen huge rafts of rock floating on a “sea” of soft rock in the mantle beneath. These rafts, or tectonic plates, fit together like the pieces of a jigsaw. But they are not stationary. They move slowly but inexorably—at about the same speed our fingernails grow. This may not sound fast, but over the course of years, it leads to some dramatic consequences: volcanoes, mountain ranges, tsunamis and earthquakes.

The theory states that Earth’s outermost layer, the lithosphere, is broken into 7 large, rigid pieces called plates: the African, North American, South American, Eurasian, Australian, Antarctic, and Pacific plates. Several minor plates also exist, including the Arabian, Nazca, and Philippines plates.

The plates are all moving in different directions and at different speeds (from 2 cm to 10 cm per year–about the speed at which your fingernails grow) in relationship to each other. The plates are moving around like cars in a demolition derby, which means they sometimes crash together, pull apart, or sideswipe each other. The place where the two plates meet is called a plate boundary. Boundaries have different names depending on how the two plates are moving in relationship to each other.

This should be enough for any one to understand that we are living on “non stable ground’. Is it normal or insane to make it even more unstable with: underground explosion Nuclear, over mining and over digging looking for oil, with very deep forage living the crust of earth with millions of large empty holes and galleries. We live on a planet where the magma (core) is between 1300 °F to 2400 °F and evolving all the time. Is it safe?

Mark Twain is supposed to have said “A mine is a hole in the ground with a liar at the top.”
