Regardless of the abundance of worlds in our solar system, scientists still are not certain how planets are created. The Earth was naturally created 4.5 billion years ago. With the rise of the sun, small particles came together and became larger particles. Proceeding these events solar winds then swept away elements, such as hydrogen and helium, leaving only rocky materials. Like many other planets, earth was created from these materials. The first stage of earth’s creation was earth's core, with heavy elements colliding together. Then dense material that was originally colliding sank to the center due to the amount of pressure, while the lighter material stayed afloat and created the crust. Continuing the creation process, earth’s magnetic …show more content…
Most geologists believe that the key forming processes of the Earth was melting of much of the inner rock material. The foundation of the heat was radioactive minerals trapped in the Earth as it formed. Gradually, those minerals released heat as radioactive chemicals. The temperature rose until the rock melted. Once this occurred, heavy portions flooded downward toward the center, while low-density minerals floated toward the surface. Eventually, they solidified into a crust of low-density rock. A great example of a rock that floated to make the crust is feldspar. The creation of the core is crucial to earth’s formation. During its history, tectonic plate movement has had a vital role in shaping modern day …show more content…
Life evolved into multicellular organisms over a billion years later. In the last 570 million years of earth’s life, these organisms began to evolve, starting with arthropods, followed by fish about 530 million years ago, then land plants about 475 million years ago and then forests about 385 million years ago. It is reported that mammals didn't evolve until 200 million years ago and Homo sapiens only 200,000 years ago. So this means that humans have only been around for about 0.004% of the Earth's history. This in reference to the video The Earth through Time created by National Geographic. These changes are not easily summarized, but nevertheless it is still incredible how far life on earth has come. Earth has experienced five major extinctions with the most recent one being of 66 million years ago. Some scientists are arguing that we are currently experiencing another mass extinction, and that it is one of the most unique one yet because it is caused by
The Mantle makes up 70% of the Earth’s mass and is mostly solid but capable of flow, causing changes in the Earth’s surface.
The traditional theory about the Earth’s core suggest that the core of the Earth is a solid nickel and iron sphere surrounded by a fluid metallic magma. The rotation of the Earth is believed to create massive columns of magma to swirl in the core. These columns are believed to produce the Earth’s magnetic field. This theory is based on the assumption that the Earth’s core is cooling and will eventually cool completely and cease to produce energy and a magnetic field. However, this theory does not answer many ongoing mysteries about the Earth, such as why the Earth’s magnetic field periodically shuts down, and questions about the energy production of the Earth. It was apparent that a new theory was needed to explain the mystery of the Earth’s core.
Frankenstein was written by a woman named Mary Shelley. This story is considered to be one of the earliest examples of science fiction. Mary Shelley did not have a good life. There were always bad events occurring in Shelley’s life. Before the age of 30, Mary Shelley had lost her mother, sister, father, husband, and three of her four children. She battled depression all of her life and finally died in London at the age of fifty-four. After all of these terrible things that happened to her, people can probably understand how she came up with such a horror story like Frankenstein. In this novel, the main character is Victor Frankenstein. After Victor mother dies, he leaves and goes to England. In England is where he created this monster that he soon regrets. Victor abandons the creature, and the creature makes it his duty to find his creator and wreak havoc along the way. This horrifying sci-fi story could only be written and told by Mary Shelley, an individual that had such a horrible life.
In the beginning there was only darkness. For many millions of years this darkness remained. There were no stars, no sun, and no earth. But one day something very special happened. The darkness created light. It was a very small amount of light but it was just enough. The light became the husband of the dark. After a long while both the light and the dark became bored. The light began to insult the dark and the light replied with equally harsh insults. "You are not as beautiful as I!" said the light. "Ha! You are much uglier than I!" said the dark.
Over the course of 408 years, from when the thirteen colonies were first founded and today, the traditions of European and Native American culture have always varied significantly. From their religious to their political views, the European and Native American beliefs have many common characteristics as well as many dissimilarities. These differences and similarities are most evident when comparing their creation stories and their constitutions.
The relative age of the earth is not often seen as a topic of controversy. Much of the scientific data published in school textbooks and taught to students indicate an age on the order of billions of years. Radiometric dating, as well as geological rock studies, have been used as evidence to support such a large expanse of time. However, a small but determined minority, mostly composed of fundamentalist Christians, has been vehemently challenging this age.
When the modern person ponders the formation of human beings, our mind automatically goes to Adam and Eve, whom were the first man and woman created by God according to the Book of Genesis. Before there was Adam and Eve, diverse cultures came up with myths about the construction of humans. These myths included: “The Song of Creation” from the Rig Veda, An African Creation Tale, From the Popol Vuh, and A Native American Creation Tale “How Man Was Created” Each one of these legends gives a diverse perspective on the creation of human beings.
Earth has gone through five fully major extinctions before. We currently are in the process of Earth’s sixth mass extinction. This mass extinction is closely related in severity to the extinction of the dinosaurs. Earth’s extinctions are broken into three different areas. The first area was the large number of animals caught by hunter-gathers. The discovery of agriculture led to the second area of extinction, wildlife habitats. These wildlife habitats were destroyed due to humans starting to stay in one area.
Modern humans have been on this planet, for approximately 200,000 years, while our ancestors have been around for about six million years. “...and the ancestors of modern humans may have survived because of traits such as large brains that helped them adapt to unstable, shifting landscapes...”
Earth was formed 4.8 billion years ago (3) . It became the home for hazelnuts because it had an atmosphere and environment which allowed for life to prosper in later years. Earth’s surface was once composed of a single landmass, known as Pangaea (1).Over time it was broken up into seven different plates which were free to move as a result of movements in the hot, semi-liquid magma beneath the...
Igneous rocks are formed from the ejection of earth’s volcanoes. Deep down inside earth’s mantle there lies hot magma. Magma is molten rock that is kept below the surface. This mixture is usually made up of four parts: a hot liquid substance which is called the melt; minerals that have been crystallized by the melt; solid rocks that have made themselves tangled in the melt because of loose materials, and finally gases that have become liquid. Magma is created by an increase in temperatures, pressure change, and a alter in composition. When this magma is ejected from earth’s crust it earns a new name called lava. The lava hardens and becomes an Igneous rock.
The Earth is a home for mankind, a planet sustaining life, and it is also a giant magnet! Magnets in general, no matter what type of magnet it is, have two end faces called poles. Poles are where the magnetic force is most effective. These two poles are known as the north pole and the south pole. Magnets also create a magnetic field from the particles within the magnet. The Earth resembles this same structure. The earth has a geographic north pole and a geographic south pole. Since opposites attract in magnets the south pole of the core of the earth points towards the geographic north pole of the earth and the north pole points towards the geographic south pole of the earth. The core of the earth serves the same purpose as the particles in m...
Earth system refers to the earths interacting physical, biological, and chemical processes. The system consists of land, oceans, atmosphere and poles. The earth system has four spheres, including the geosphere, the hydrosphere, the atmosphere, and the biosphere. The geosphere refers to the solid parts of the earth system, including earth’s rocky crust, mantle, and the metallic core. Within the geosphere is the lithosphere, which only refers to the uppermost layers of solid earth. The uppermost layers of solid earth are the oceanic and continental crust rocks. Just below the crust is the mantle, which is composed mostly of magnesium and iron silicate minerals. The mantle accounts for about 2/3 of the
The interior structure of the earth is made up of crust, the mantle and core (inner core and outer core). Earthquakes occur on the crust. Crust forms the external layer of the earth surface. On the crust, the plate tectonics forces are in charge of causing the abrupt earth movements. Due to the existence of an immense temperature and concurrent pressure difference in the outer layer and inner layer of the earth, convection currents occur at the mantle. This energy results from overwhelming decomposition of radioactive substances contained by the rocks found at the interior of the earth. The developed convection currents lead to movement of lava; cold lava finds its way to the interior of the earth crust, while the molten lava which is generally hot, leaves the interior of the earth to the outside of the earth crust. These kinds of circulations occur at different locations of the earth surface and consequently results in segmentation of the earth due to movement in different directions.
