Information Report On Our Planet Earth

Scientists have found that the Earth was formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. As gravity slowly gathered this gas and dust together into clumps, it became asteroids and small early planets called planetesimals. These objects collided repeatedly and gradually got bigger, building up the planets in the Solar System. Although scientists are very close to answering the question, they still continue to search for the exact answer to how the Earth was created. With all the evidence presented, it is hard to refute from scientific theories. This becomes cumbersome to many religions because in their eyes God has always been the creator of the Earth.

In the beginning, God created the universe. At first the earth was shapeless and covered in

The currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state.

The evolution of that formation created the world we live in today. The earth has been in existence for a little over four point five billion years to be exact. The earth shares a story that we are still exploring. From its colorful coral reefs in bright and vibrant

Major Geological Event: The Earth was formed by gravity pulling debris into a swirling mass of rock, radioactive decay and rock impacts generated large amounts of heat melting the planets together. Gravity allowed it to gain the spherical shape it has. Materials in higher density formed the core (Iron, Nickel) while materials in lower density became the mantle and crust. Tectonic plates moving around so much made Volcanoes and the gasses released slowly formed the atmosphere. First signs of life increased the oxygen content, and in turn caused Oceans to form from the rain.

“The early Earth was probably partially or largely molten” (The Solar Nebula. N.d). Over time the earth cooled and the crust was formed. “Much continental crust, the most silica rich and least dense kind, has been produced by 2.5 billion years” (The Solar Nebula. N.d). Over a period of time and a series of volcanic eruptions water vapor was thrown into the atmosphere and eventually condensed to form the oceans. From a spinning cloud of dust the evolutionary process began and the Earth that is inhabited today came into existence according to the nebular hypothesis.

Earth as we all know it's Associate in Nursing improbably complicated and fragile network of interconnected systems that have developed slowly over the last four.5 billion years more or less. From the ashes of the massive Bang, this planet emerged as a mass of energy and components. From that new born mass of energy and components evolved structured, dynamic systems of solids, liquids, and gasses. The evolution of this planet continued to unfold over billions of years in such a novel method that eventually conditions arose with the flexibility to foster life.

Throughout time people have held different ideas of what the universe looks like, from the Aristotelian universe centered around the Earth to the Copernican universe with our Sun at the center. After Sir Isaac Newton invented physics,

The Big Bang Theory is the name given to mark the event of the birth of the universe and is the scientific theory about what happen in the earliest moments of the universe, and how the universe was an extremely hot and dense of subatomic particles and radiation. The big bang let insights about how old the universe is and the universe is 14 billion years old and it has changed throughout its time.

The Earth was formed about 4.54 billion years ago in one in many galaxies. After many years have passed the Earth has evolved and land was created. Many species have formed also the life of nature. The land provides humans nutrients and resources for people to survive, such as nourishing foods and materials for building shelter.

Many things prove the Big Bang theory is true and the steady state theory is wrong. The Big Bang theory states; all matter and energy in the universe was compressed into an extremely small volume that 13 billion to 15 billion years ago exploded and began expanding in all directions. The steady state theory states; the universe is always expanding but maintaining a constant average density. Red-shifted light spectrum, cosmic background radiation, and the composition of matter all take part in supporting the Big Bang theory.

It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core and mantle formation, as well as the eventual production of the continental crust.

When space and the universe began, the existence of time also began. This theory is well-known as the Big Bang Theory. About fifteen billion years ago, the universe was comprised of very hot compressed gas, as a fireball. This is contrary to the idea of the universe beginning as a lump of matter somewhere in the void of space. Matter was created as a result of the Big Bang.

We now focus our attention on the formation of one particular planet, one that is so far unlike any other in the universe, Earth.

Astronomers believed the Universe was created about 14 billion years ago. During that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead, and it was insanely hot and dense. Out of nowhere this little bubble started expanding. This expansion created what we know as the Universe. In such little time the Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing.
