Is Mineral Evolution A Frame For Understanding Minerals And All The Stages And Process That Created Them?

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.

It took millions of years for the earth to form, but the modern world is destroying it by speeding the reactions.No one has time to wait for the crops to take time for its full nourishment. Scientists use chemicals, harmful chemicals to accelerate the reaction

Describe the important chemistry of early earth and how this may have given rise to life forms.

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

There are two types of minerals that we find in Earth - rock-forming and ore minerals.

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

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.

Anthropogenic materials refer to anthropogenic deposits that are the by-products of human activity such as manufacturing, mining, construction, and the waste disposal or the creation of landfills. Materials manufactured by humans such as glass, plastics, or metal alloys are geological markers of a new era because they have never been seen before in the earth’s history. These are permanent geological markers which indicate migration of peoples and the changes in human history. Therefore they are representative of a new era in which humankind have started to alter their environment for their own benefit instead of adapting to the existing environment to survive. These markers are also indicative of a new era of innovation, the creation of materials previously non-existent i.e plastics, show that humans have altered resources and materials to create their own environment most favourable to them through the use of new technology and tools. These materials will be preserved and will be able to help future generations distinguish different time periods of human existence and the various geological status of the earth. Therefore, it is only logical to begin to classify a new era beginning at the time where these materials have begun to make their way into the stratigraphy of the

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.

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.

The oxygen revolution: During the Proterozoic, biotic system were being established, which gave rise to biomass of the prokaryotic organisms like the “benthic and planktonic photosynthesizing organisms” Due to the vast developing diversity of environment, organisms could well adapt to these various environments, which increased the input of oxygen on Earth. Hence, in order for the oxygen to be accumulated in the atmosphere, Iron and Sulfur like oxygen-sinks had to be depleted.

The article I chose was “How Life and Luck Changed Earth’s Minerals” by Roberta Kwok on Wired.com. Recently, geologists have been wondering if the evolution of minerals is a predictable outcome due to Earth’s chemistry or if the evolution is a result of random chance (Kwok, 2015). They have also been wondering that if we found a planet similar to Earth, would the minerals and gemstones match up with our own. Mineral physicist Robert Hazen and his colleagues at the Carnegie Institute of Washington’s Geophysical Laboratory decided to tackle these questions in their research, and their findings have given us insight into the nature of mineral evolution.

In the beginning, impacts of very large objects were very common, some as big as Mars or half the diameter of Earth. Collision of large bodies orbiting Earth played a role in its initial tilt of spin axis, the length of its day, direction of spin, and the thermal state of the interior. This violent bombardment continued for 3.9 billion years. Final composition of Earth had several crucial structural effects. Enough metal was present early on to allow formation of an iron and nickel rich core that is partially liquid. This enables a magnetic field that deflects some harmful radiation from reaching the surface. Enough radioactive elements are also present in the core to maintain long term heating which drives plate tectonics. At 4.5 billion years ago, Earth separated into different layers: an inner core (made of iron and nickel), a land layer of lower density material, and an early atmosphere of carbon dioxide and steam. At 3.9 billion years ago, surface temperatures dropped to a range where liquid water could be maintained. Liquid water makes up approximately 75% of the planet's surface today which is roughly what it was then. The most important requirement for life as we know it is the presence of liquid water. This is the one substance that can serve as a universal solvent - that is, it can dissolve and transport minerals and

According to astronomical research and geological evidence, scientist indicate the universe is approximately thirteen thousand eight hundred and twenty billion years old. The first link to humanity started with a primate group called Ardipithecus. While our ancestors have been around for about six million years, the modern form of humans only evolved about two hundred thousand years ago. The age of the Earth is estimated about four point fifty four billion years because that is the age of the oldest rocks with fossil evidence of life on earth. The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are four point three billion years old. The study of the origin of life on Earth, more specifically abiogenesis, is the natural process of life arising from non-living matter. Life on Earth is believed to have began from organic compounds about three point eight to four billion years ago. Despite several competing theories for how life arose on Earth scientist only know when life first appeared on Earth and are still far from answering how it appeared. Since it is hard to prove or disprove them, no fully accepted theories of the origin of life exists.

Surprisingly, the clay held almost 30 times more iridium than the limestone layers above and below the clay. Similar layers in other parts of the world gave the same results. The conclusion was that a giant meteorite hit the Earth 65 million years ago and had released a large
