What are the scientific theories of how how the world was created? How ever the world was created, there are a few ideas on how the earth and it's creatures evolved. The Creation Sciences (the old earth [earth is 14 billion years old] and the new earth [earth is 10,000 years old]) both imply that the world was created by God, and no biological evolution occurred.

- The three main layers of the earth are the Core, Mantle and Crust. The Core is mostly made from iron and nickel, the Crust from oxygen, silicon and aluminum and the mantle sil…icon,oxygen,iron and magnesium. 19 people found this useful.

plate tectonics The theory, or idea, of plate tectonics says that Earth's outer layer is made up of large, moving pieces called plates. All of Earth's land and water sit on these plates. The plates are made of solid rock.

The Earth's Layers Lesson #1 The Four Layers. The Earth is composed of four different layers. Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron).

Layers of the Earth Facts Core of the Earth Facts. The core is made of two layers – the inner and outer core. When the Earth formed 4.5 billion years ago, the heavy substances sunk to the middle and these formed the inner core. The lighter ones are like air and water stayed on the top on the crust.he core is made of two layers – the inner and outer core.

- Five Serious Theories. 1  The Fission Theory: The Moon was once part of the Earth and somehow separated from the Earth early in the history of the Solar System. 2  The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.

- It was concluded that hot rock from the mantle was rising up through the lithosphere and pushing the sea floor—and the continents on either side—apart. This finding provided the mechanism to explain the purposeful movement of Earth’s plates and led to the development of the first theory of plate tectonics. Today Cooper is among a new generation of geologists who study what could be called “post” plate tectonics. Taking the field up a notch, she investigates similar processes on other planets and asks why Earth has plate tectonics in the first place.

- Earth’s crust is made of rock, and rock is made of natural substances called MINERALS. There are three main types of rock—sedimentary, igneous, and metamorphic rock. Each type is produced in different ways.

Plate Tectonics The theory of plate tectonics itself says that the Earth's lithosphere is made up individual plates that are broken down into over a dozen large and small pieces of solid rock.

What's the current theory of how the moon was formed? · just now. 1  Current theory is that a large 'wandering' planet, roughly the size of the moon impacted with the earth destroying the earth then a new earth and the moon formed. 2  Another planetary body, Orpheus, collided with Earth at an angle and sent debris into space. 3  There are lots of theories. 4  rock hit earth, moon formed.

Plate Tectonics Tectonic theories attempt to explain why mountains, earthquakes, and volcanoes occur where they do, the ages of deformational events, and the ages and shapes of continents and ocean basins.

7 Theories on the Origin of Life Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup? One theory involved a shocking start. Another idea is utterly chilling. And one theory is out of this world! Inside you'll learn just how mysterious this all is, as we reveal the different scientific theories on the origins of life on Earth.

StarChild Question of the Month for October 2001 Various theories had been proposed for the formation of the Moon. Below these theories are listed along with the reasons they have since been discounted. The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.

- In 1770's, James Hutton, Father of Geology (Scotland, 1726-1797) published `Theory of the Earth' in 1785. Demonstrated that Hadrian's Wall was built by Romans and that after 1500 years there was no change. Thus, he suspected that Earth was much older than 6000 years. This is the theory of uniformitarianism, that slow processes shape earth. Mountains arise continuously as a balance against erosion and weathering. Present is key to the past.

4 theories about how the moon formed Also known as the condensation theory, this hypothesis offers that the moon and the Earth formed together while orbiting a black hole. However, this theory neglects an explanation of why the moon orbits the Earth, nor does it explain the difference in densities between the moon and Earth. 4. Giant impact hypothesis

- Wegener's drift hypothesis also provided an alternate explanation for the formation of mountains (orogenesis). The theory being discussed during his time was the Contraction theory which suggested that the planet was once a molten ball and in the process of cooling the surface cracked and folded up on itself.

Science for Kids Some of them constantly moving! You can think of the Earth as being made up of a number of layers, sort of like an onion. These layers get more and more dense the closer to the center of the earth you get. See the picture below to see the four main layers of the earth: the crust, mantle, outer core, and inner core.

Layers of the Earth Facts There are always new theories coming out as measuring equipment and knowledge improves. Core of the Earth Facts The core is made of two layers – the inner and outer core. When the Earth formed 4.5 billion years ago, the heavy substances sunk to the middle and these formed the inner core.

The Earth forms The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called planetesimals. These objects collided repeatedly and gradually got bigger, building up the planets in the Solar System, including the Earth. The details of how the Earth formed are still being worked out.

Expanding Earth There are 3 forms of the expanding earth hypothesis. 1  Earth's mass has remained constant, and thus the gravitational pull at the surface has decreased over time. 2  Earth's mass has grown with the volume in such a way that the surface gravity has remained constant.

- This  theory was proposed independently by two scientists - A.I.Oparin, a  Russian scientist in 1923 and J.B.S Haldane, an English scientist,  in 1928.    5. Theory of Catastrophism   This theory on the origin of life is simply a modification of the  theory of Special Creation.

- L ithosphereAsthenosphere Oceanic crustMantle Partial melt Asthenosphere CrustMantle L ithospherePartial melt Plate Tectonics Plate tectonics theory describes how the lithosphere of the Earth is broken into various plates. These plates drift on the asthenosphere at very slow rates. As plates move away from each other the lithosphere thins and tears. At these divergent plate boundaries new oceanic lithosphere is created in the gaps from upwelling magma from the mantle.

Earth's crust Earth's crust is Earth's hard outer layer. It is less than 1% of Earth's volume. The crust is made up of different types of rocks: igneous, metamorphic, and sedimentary rocks. Below the crust is the mantle. The upper part of the mantle is made up of peridotite, a rock denser than rocks common in the crust. The crust and the upper mantle make up the lithosphere.
