Around 4.6 billion years ago, our universe was born by accretion from the solar nebula known as the Big Bang. As the sun heated up, this orbiting matter accumulated and unavoidable mass of larger bodies collide to successively create protoplanets with its own gravitational pull. During this period, Earth was nothing but molten rock from the collision with other bodies and volcanoes, temperature reaching over 2,000 fahrenheit. Not only that, but Earth then, would’ve been toxic to humans and modern life because of the lack of oxygen. Only carbon dioxide and nitrogen were presented and some water vapor. One massive planetary collision has thought to be the reason behind Earth’s tilt and the formation of the moon. As more and more meteors and other bodies continuously impact with the Earth’s surface, the Earth’s gravitational pull became stronger, giving the moon the ability to orbit the Earth. After 1 billion years of volcanic and other meteor activities, Earth finally was able to cool down and some form of life erupted. Before there was any sort of life, there was oxygen, before there was oxygen, there was water and till this day, theres no clarification on how Earth is the only planet in the universe, rich with water.There are several remarkable theories on how water came to existence billions of years ago. One is that from the gas from volcanic activities, the Earth rain for years and years, supplying it’s surface with 75% of water. Another theory is that water originated from the universe. H2O can not exist in outer space, but H and O can, separately. Hydrogen is the basic building material in the created in the Big Bang when our universe was newly formed. Oxygen exist in the process of star fusion, where stars get their energy from like the sun. If you combine H and O, you have H2O, water, which means there are enormous amount of water in space, but the only problem is, theres more hydrogen than there’s oxygen. For example, the sun only has 0.8% oxygen, the rest are mostly hydrogen and helium. The Earth was a suffocated place 2.5 billion years ago until oxygen level rose up. As mentioned in the previous text, Earth has been filled with water from who knows where, but it still lacks oxygen, the key to every living thing. Oxygen is also one of the greatest mysteries when it comes to its origin. It has been thought that oxygen was created from cyanobacteria. Cyanobacteria are single cell organisms, they are just a DNA that lives under water. Cyanobacteria are also the first life form that appeared on Earth, 3.5 billion years ago. These newborn single cell obtain their energy through a process called photosynthesis, where the sun is the main source of energy. Through photosynthesis, these living things, like today’s plants, it has the ability to produces oxygen and glucose, the key factor of the future generation species that would soon roam the Earth. As oxygen fills up the Earth’s atmosphere, many life forms appear. Despite bacteria being the first known life forms on Earth, scientists have discovered that sponges are also considered the earliest living thing on Earth. In 2012, the oldest evidence of a sea sponge found was a fossil discovered in a 760-million-year-old rock. This beat the previous record for oldest sea-sponge fossil, a 635-million-year-old sponge discovered in 2009. There may be still older fossils yet to find, but finding an older species is unlikely, as these simple organisms appear to be the progenitors of much more complicated life, including the first multicellular animals. First multicellular organisms arise from a single cell bacteria that generates multi-celled organisms, like plants, fungi, animals, and algae. Although there are many organisms, there is no clarification on how these cells came to be as animals, only theories. Roughly 600 million years ago, life evolves in the sea, plants and sea creatures dominated the Earth. Yet, for most of the Earth’s existence, the only form of life has...
...front of him, he couldn’t think so. This conflict between his doubting and reasoning mind and emotionally overflowing heart caused him to be resentful.
Why was Joe Morgan relieved to see Andrew Manson? Joe Morgan's wife was about to give birth to their child. Andrew was the doctor who was to carry out the delivery. Morgan was anxiously waiting outside for the news of his child. Since Andrew was able to save the child, it changed his outlook towards life. He was relieved to see him because he had saved Morgan's new born baby.
What dilemma was Andrew caught in? How did he resolve it? Post an hour's long and harsh struggle, the child that Andrew had helped to deliver was born lifeless. As he gazed down at the still form, Andrew shivered to think how he had failed to keep his promise of delivering the baby safely. He hesitated, he was torn between the desire to attempt to resuscitate the child and his obligation towards saving the mother who was in a desperate state after the birth of her child. The question at hand was whom to save, the stillborn baby or the mother whose heart was still beating. The dilemma was so pressing that he did not resolve it consciously, he blindly and instinctively chose to pay attention to Susan Morgan, the mother who now lay collapsed, with almost...
...things to survive. A stable environment is the key to survival. Through-out many years, things Earths systems have been changing drastically. The outcomes of change can be good or bad. The Earth is warming faster than ever before, and humans are to blame. Ever since the industrial revolution, (which began during the mid-1800s) humans had affected the Earth’s atmosphere drastically. We have quickly attained a mass amount of geological force in terms of our ability to change the atmosphere so easily. Human population has been constantly escalating rapidly, ever since 1900. About 7 billion people are living right now! With such a large population, there has been an increasing need for products. Carbon Dioxide is a “Greenhouse Gas”. Greenhouse Gasses can trap heat in our atmosphere. Carbon Dioxide levels have increased by over 30% due to the large amount of coal and oil being burned. Adding more and more air pollution is making the air we breathe toxic. This is just one of the many examples of how the Earths systems are changing drastically.
Earth’s System Essay
Earth’s system and its changes contribute a lot to human life as we know it. There should be a balance in order for most living things to survive. A stable environment is the key to survival. Through-out many years, things Earths systems have been changing drastically. The outcomes of change can be good or bad. The Earth is warming faster...
1. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by scientists studying the salinities of the oceans, the rates of sedimentation, and models of cooling of different materials in order to calculate the Earth’s age. In 1862, William Thompson calculated the Earth’s age to be 98 million years and recounted that age to determine that it was actually between 20 and 40 million years old. He used a very good method but ended up being wrong on both counts because he was unaware of the existence and all the effects that radiation caused. There was another method of aging the Earth utilizing the relative positions of rock layers. Fossils were used as benchmarks, and understanding what rocks are older than others. This relative aging helped to develop a geologic time scale. The discovery of radioactivity allowed scientists to understand heat better. The radioactive decay of elements helps scientists calculate the age of an object by using the statistics of large numbers.
2. The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, as the Earth's Moon, may be the...
...Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world or the Blue Planet.
Earth formed approximately 4.54 billion years ago, and life appeared on its surface within its first billion years. Earth's biosphere then significantly altered the atmospheric and other basic physical conditions, which enabled the proliferation of organisms as well as the formation of the ozone layer, which together with Earth's magnetic field blocked harmful solar radiation, and permitted formerly ocean-confined life to move safely to land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist. Estimates on how much longer the planet will be able to continue to support life range from 500 million years (myr), to as long as 2.3 billion years (byr).
Earth's lithosphere is divided into several rigid segments, or tectonic plates, that migrate across the surface over periods of many millions of years. About 71% of the surface is covered by salt water oceans, with the remainder consisting of continents and islands which together have many lakes and other sources of water that contribute to the hydrosphere. Earth's poles are mostly covered with ice that is the solid ice of the Antarctic ice sheet and the sea...
...3.) List four facts that characterize the oceanic ridge system.
Four facts that characterize the oceanic ridge system are: firstly, it represents 20 percent of Earth’s surface, the oceanic ridge system winds through all major ocean basin like the seams on a baseball. Ridges vary in width from 600 miles to 2500 miles. The mid-ocean ridge represents an area where, lithospheric plates move apart and new crust is created by magma pushing up from the mantle . Also, the mid-ocean ridge system is an example of a divergent plate boundary.
4.) Briefly describe the process of continental rifting. Where is it occurring today?
As crust is pulled apart, rifts are formed and eventually become large enough for ocean to form. This is occurring today in the East African rift.
2.) Compare a continental volcanic arc and volcanic island arc.
In a continental volcanic arc mountains formed in part by igneous activity associated with subduction of oceanic lithosphere beneath a continent. In contrast, volcanic island arc is a chain of volcanic islands generally located a few hundred kilometers from a trench where active subduction of one oceanic slab beneath another is occurring.
1.) What is the age of the oldest sediments recovered using deep-ocean drilling? How do the ages of these sediments compare to the ages of the oldest continental rocks?
The age of the oldest sediments recovered using deep-ocean drilling is 180 million years. The age of these sediments...

...The Origin of the Earth, One of God’s Hidden Secrets
“Much of geology is pure speculation and is as such on the same basis as philosophy, or must be accepted on faith, as the truths of theology” (Rehwinkel 177). For geologists this means that any theory of how the Earth, atmosphere and life originated, takes faith to believe, whether it is the evolutionist’s view or the creationist’s view. Creationists believe that the Earth was created 6000-7000 years ago. This number is based on what the Bible says. Evolutionists believe that the Earth was formed 4.6 billion years ago. (Tarbuck 598) This number is based on the subjective choice of scientific evidence. Creationists have faith that the Bible is true and that there is an Almighty God who created everything. Evolutionists have faith in their theories about how the world works. Using theories based on how the world words today they try determine how the world worked in the pat.
What do Evolutionists say about the Origin of the Earth?
Where did the Geological Column of Earth come from?
According to evolutionists, the universe started from a single catastrophic event now called the Big Bang. Protons, neutrons, and electrons were formed, and they bonded to form helium and hydrogen. Helium and hydrogen collided and underwent nuclear fusion, creating stars in which the lighter elements were made. When the stars collapsed in a supernova, the...
