). The earlier basaltic crust was mostly lost due to the bombardment of asteroids. These were The following figure shows these layers of coal and sediment in the Cherokee Group of the Middle Pennsylvanian Series. . You also have the option to opt-out of these cookies. This event created the layered structure of our planet, with a solid metallic core, liquid metal mantle around it, with a solid crust forming later. Still, many Earth mysteries remain to be solved like the reason for occurrence of ice ages, the mechanism behind creation of the terrestrial magnetic field, its reversal, and much more. For all you fisherman out there, it was also known as the “Age of Fishes”. These climate changes set the stage for the recovery from the extinction of the Late Ordovician Period. Here, we will focus on the protoplanetary disk, which surrounded this central protostar, that eventually condensed to become our solar system. These continents drifted on a sea of mantle, causing plate tectonics. How the first unicellular life forms evolved in oceans, is still a matter of research. But opting out of some of these cookies may have an effect on your browsing experience. The Energy Conservation Law states that matter and energy This caused a decrease in the carbon dioxide of the atmosphere resulting in a climate cool down. Most minable coal seams in this area are from 1 to 3 feet in thickness with about a dozen seam at various elevations. As a result, these dense layers of wood and dead vegetation would eventually form into coal beds at the end of the Mississippian and throughout the Pennsylvanian periods. During the early Cambrian, the planet was recovering from the earlier Snowball Earth. In the southern part of the continent seed fern forests of the Glossopteris flourished. The third extinction event marked the end of the Paleozoic Era. trilobites. Not all that old considering the Earth is only 1/3 the age of the observable universe but very old compared to the time we have lived here. As the Earth cooled The latter half of this eon is known as the late heavy bombardment. In the early part of this era, geological strata started being laid down in shallow seas. 3rd Permian-Triassic Extinction – 96% of marine and 70% of Land species go extinct – 251 million years ago. ), an ozone layer, and the right mixture of elements in the atmosphere, especially oxygen, and a geologically stable planetary crust. They are eternal. If you have ever looked at the clay layers (called underclay) directly below the coal seam, you could still see the former upper topsoil layer know as the A-Horizon. While special creation believes in the existence of a supreme being who created the earth, organic evolution and materialistic theory believe in the progression of organisms from one state to another. Each cycle would deposit additional sediment over multiple layers of peat. This stratum is typical of that in Southeast Kansas and Southwest Missouri where most of my mining experience was located. During the Pennsylvanian (also known as the Upper Carboniferous) Period, Euramerica and Gondwana had already merged causing the mountain building of the Hercynian in Europe, the Alleghenians in North America, and the southwesterly extension of the Appalachians known as the Ouachita Mountains on the Arkansas and Oklahoma border. This stratum is clearly visible in many parts of our planet such as the Grand Canyon in Arizona, where the ages of the lower strata are as old as 2 billion years and the upper strata as young as 200 million years. The coal seams of Southeast Kansas and Southwest Missouri.

(A Kansas Corporation), The Permian Period – The Seventh and Final Period of The Paleozoic Era – Lasting 48 Million Years – From 299 to 251 Million Years Ago – The Age of Earths’ Greatest Extinction, The Pennsylvanian Period – (The Second Sub-Period of the Carboniferous Period) Lasting 19 Million Years – From 318 to 299 Million Years Ago – The Age of the Giant Coal Swamps – First Reptiles Appear Laying Eggs on Land, The Mississippian Sub-Period – 1st Half of the Carboniferous Period Lasting 41 Million Years From 359 to 318 Million Years Ago, The Devonian Period – Lasting 57 Million Years From 416 to 359 Million Years Ago, The Silurian Period – From 444 to 416 Million Years Ago, The Ordovician Period – Lasting 44 Million Years From 488 to 444 Million Years Ago, The Cambrian Period of the Paleozoic Era – 542 to 488 Million Years Ago, The Proterozoic Era Lasting 1.958 Billion Years – From 2.5 to 0.542 Billion Years Ago, The 4.6 Billion Year History Of Earth – Hadean and Archean Era – Lasting 2.1 Billion Years – From 4.6 To 2.5 Billion Years Ago. Again we have science and scriptures in much agreement. That process accumulated sediment for more than 100 million years creating several thousand feet of rock, shale, and coal that compressed the sediment layers into rock and the peat layers into the various coal seams we have today. million years ago, Silurian Period from 444 to 416 The process of oxygenation of the Earth’s atmosphere is now underway. For instance, we know that Caleb was 40 years old when he was sent with the other spies to Canaan (Josh. Hawaii Volcanoes National Park. Water in the form of ice also impacted Earth and immediately vaporized into a newly forming atmosphere. This would cause a drop in the sea levels that drained the water from the top of the sediment layers that had developed during the flooding period. Some of these fossils can be seen in the above photo. The Precambrian Era, or Super Eon, spans from the time of the Earth's formation around 4,500 Ma, till the evolution of macroscopic shelled animals of the Cambrian Era. Since termites had not been created yet and bacteria, at that time, could not produce the enzymes needed to digest wood and dead vegetation, the peat accumulated to vast thicknesses. Age of the earth 101 evidences for a young age of the earth and the universe. and as the energy particles expanded they cooled and began to condense into Published: 4 June 2009, last updated 18 September 2019. This demarcation line formed 359 million years ago at the beginning of the Mississippian sub-period. The land is turning green with mossie forest, bacterial and algal mats from the Silurian period. Earth is our home and perhaps the safest place in the universe. Peat transformed into coal as a result of the heat and pressure created by the weight of the sediment layers. million years ago, Ordovician Period from 488 to 444 (, ) Also, there is a debate about whether life evolved on Earth or was seeded by impacting asteroids (called the. It shows more detail such as the formation of the Earth’s foundation, Moon, various rocks, fossils, and the progressive creation of various life forms. Leeches and scorpions also made their debut. By this comment, no divine origin is hinted. The melting of Snowball Earth and the lack of sea ice caused rising sea levels that flooded large areas of the continents with warm water creating shallow sea areas ideal for an abundant variety of aquatic life. Glaciers receded around the mid-Permian period as the climate gradually warmed, drying the continent’s interiors. It’s all relative. It can However, polar ice caps did dominate the southern pole.

Beneath the suburbs of north-east Cairo lie the ruins of Iunu, the Biblical On, or Heliopolis as it was known to the Greeks. up to 25 feet (10 meters) and became the dominant predators of this period. This drift would eventually lead to a collision with the equatorial continent of Euramerica to form Pangaea. The Creation. The rising sea levels would cause seawater to flow inland flooding the accumulated peat for long periods. It is affected by a number of factors such as speed, gravity, mass, and energy, all of which can slow or almost stop the flow of time to one observer, while another observer, not influenced by these factors, sees time flowing at a much faster rate. As the fraction of heavy elements in the whole content of our solar nebula was quite less, compared to Hydrogen and Helium, terrestrial planets like Earth are small, compared to the gas giants. Our instruments do not allow us to look back at the birth of Also coming on the scene were giant dragonflies (some with wingspans up to 2 ½ feet), more than 800 kinds of cockroaches with some reaching 3 feet in length. The following figure shows how the Snowball Earth would have looked. This period was relatively warm lacking any glaciers. This iron core is responsible for the magnetic field that surrounds the Earth protecting our atmosphere from solar winds. Creation of Earth. only be changed from one form to another. You would be on the single largest landmass of our planet’s history, the “C” shaped supercontinent of Pangea surrounding the Tethys Sea. 5th Cretaceous-Paleogene Extinction – 75% of all species go extinct – 66 million years ago. They always existed, exist today, and will exist periods of time call Eras or Eons. at 11.58 p.m. Our entire human history gets compressed in a time frame of less than 2 minutes! Reptiles that could better cope with these conditions rose to dominance.
