ReplyDeleteEarth was formed the same way as all the other planets,sun,and stars were formed. The ball of gases changed from white to yellow, then yellow to red. It turned red because it give any light off. Earth started to cool down.Earth contracted and got very small. The gases changed to liquid. Heavy materials grew in the middle of the Earth. The Earth's liquid.

ReplyDeleteEarth formed like 4.54 billion years ago, and life appeared on its surface within almost one 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 earth was initially formed from the same disk of dust and gas from which the sun itself coalesced. When the mass of the earth increased so did the gravitational force it exerted. The impacts of large bodies and the decay of radioactive elements generated heat that melted the materials of the young Earth. The Earth was formed over 4 billion years before any life appeared.

The earth was a glowing ball of gases.The gases were very hot.After billions of years the earth cool down.The ball of gas stop spinning and the color changed.It change form white to yellow to red after this the earth got smaller.The gases change to liguid when the gases cooled down.Heavy material peacenpered the earth.Thats how the earth was born.
ReplyDeleteThe core has two parts one part is the inner core.The inner core has pressure so that metal are pushed together.The inner core is about 4,000ml underneath the crust. The inner core is 800ml thick. It also, couls reach 9,000 degrees farenheight
The other part of the core is the outer core.The outer core is made of iron and nickel.The outer core is 9,800ml beneath the earth surface.The outer core is a liquid layer.This is what i reseached about the core of the earth

The earth was form by volcanic gasses which gave the earth its shape and depth in volume the earth is made in layers . The bottom of the earth layer is named as the core .many believe the earth was made before anyone live to be estameted to have formed from 4.5 billion

Just how was the earth created? The Earth was formed in the same way the sun, planets, stars.At first the earth was a hot glowing ball of white and hot gases with a compresses and giving off a lot of heat.This probably happen million of years ago.Then finally the Earth cooled down.The ball of gas slowed down from spinning and the colors change from white and yellow to red to not giving off any light at all.

The Earth was formed the same way as all the other planets, sun, and stars. First the Earth was a hot glowing ball of white gases that was millions of degrees Fahrenheit. Then after a million years the Earth started to cool down. Then the ball of gas stopped spinning in motion and changed colors. The ball of gases changed from white to yellow, then yellow to red. It turned red because it give any light off.
ReplyDeleteAfter this happened the Earth contracted and got very small. The gases changed to liquid. Heavy materials grew in the middle of the Earth. The Earth's liquid material . Then the mantle was formed. That's how the Earth was formed.
The Core
The Core has two parts to it. One part is called the inner core. The other part is called the outer core. The inner core has temperatures and pressures so that the metals are squeezed together. The inner core begins about 4000 miles beneath the crust. The inner core is 800 inches thick and could reach 9000 degrees Fahrenheit , the pressures are 45,000,000 pounds per square inch.
The outer core is a liquid layer. It is 2,266 km thick. It is made of iron and nickel. It is above the inner core. Its outer boundary lies 1,800 miles beneath the Earth's surface. This is what I learned about the core.

ReplyDeleteThe Earth's formation started from the same disk of dust and gas from which the sun itself coalesced.The mass of the earth increased the gravity force extered and bombarded by objects from space in size from dust particles to small planets.The material started to incrase on the earth and large bodies generated the heat of the melted materials.
ReplyDeleteIt started to form a solid crust allowing liquid water to exist on the surface.The first life forms appeared between 3.8 and 3.5 billion years ago.It happened with radioactive elements and frequent asteroids,Earth lost heat to space and slowly cooled.Also with minerals it cooled down the Earth and segregated into an iron core and silicate mantle.
The core is a huge ball of liquid and solid iron.It protects us from the dangerous radiation of space.Sice it was mostly liquid heavier elements like iron and nickel were able to sink down into the planet and assemble the core. By Joel Gonzalez

Earth has been around for many years,one question many ask is how was it formed.Some have a religuse way of how it was created, some scientist say that it was created by a rok, the most biggiest theroy was the BIG BANG THEROY. Most belive thatthat that the earth was formed by a rock that exploted and made planets witch is called the BIG BANG THEROY. The earth was created by disk , dust and gas the sun created. The mass of the earth incressed and became bigger. With space's help gravite came along, it got bigger and bigger unff tobecome a planet that is my theroy. by ALPHA BARRY
ReplyDeleteThe one and only "BIG BANG THEORY" Great information Alpha! Your information is awesome. I enjoy reading your thoughts on how Earth was formed and the BIG BANG THEORY.

How was the Earth created, why wasn't it a square, or triangle. This essay will help you understand earth's formation.
ReplyDeleteThe Earth's crust consists of 2 basic types, balsalt and granitic rock. Granitic rock is also known as continentil crust is found under various mountain ranges. The balsalt is also known as oceanic crust.
Continentil crust has a core foundation made up of very old granite, gneiss, schist, sedimentary, and volcanic rock. Some of these rocks go back about 3 billion years. Continentil crust ranges between 10 and 70 kilometers in thickness.
Oceanic crust is constantly being created at different oceanic ridges. Magam erupts on the ocean floor and pushes the old rock away. This type of crust is about 7 kilometers thick.
These 2 crust together help to form the Earth's core. They both have area where volcanoes are formed. When volcanoes erupt new land forms are created.

How I think the world was form was by a mistake. I think its really formed when gases and materials particulars that were found in outer space.
ReplyDeleteI believe Earth was a happy mistake, because look at us now, isn't it a good thing? In some way there was a huge big bang. In that big bang were small bacteria cells. Slowly evolution took place and then grew trees, grass, and other types of plants. Water was made and the bacteria from the big bang interacted with it and slowly grew as if they were those toys that would grow with water applied. The dinosaurs were made and the food chain was made too. Slowly, but surely, Earth grew to what we are today. But who ever said Earth was done evolving? We have a long time to go.
ReplyDeleteLets see if hover boards get created in 2015, or Back to the future is a lie.
I'm just going to reply to myself. If that's an issue, well it already happened. Plus you can't catch a person on a Narwhal that shoots lasers from its horn! I will evil laugh at your despair.
DeleteI agree with you Ariel we as earth have come a long way . Although I believe earth was Mayes by a collision .

ReplyDeleteThe Earth was formed 4.6 billion years ago from the same nebula cloud of gas and dust that the Sun and the eight other planets were formed. However, Earth then was very different from Earth now, and it would have been impossible for life to exist on it. In fact, it is only quite recently in the Earth's 4,600,000,000 year long life that life, resembling modern-day life, has been possible, first with the dinosaurs over 200,000,000 years ago and now with humans and other animals. The Earth is still being formed now. It still has a molten centre which causes volcanoes to ocassionally erupt, and plates on the surface are constantly "swimming" meaning that they collide with other plates and cause earthquakes.
Earth is still developing. Volcanoes still erupt, the earth still shakes, weather still forms landscapes. Creatures evolve. Some die out, some develop. The creatures that die out do so because they are not suitable for the planet's current conditions. Creatures that survive and flourish do so because they are more adapted to the new conditions.

and no i did not copy anybody
Deletemy opinion on how earth was formed was that many meteors clumped together making a big rock. this giant rock was traveling through space getting bigger and bigger. it slows down slowly, shaping the giant meteor in to a roundish planet. the meteor stops in the "Goldilocks" zone where life was possible since it wasn't to far from the star that is known as the sun. it wasn't to far, it was just right.
ReplyDeleteKedwin , I totally agree with your opinion
ReplyDeleteMy opinion on how rocks form is surprising, but cool. I never knew that rocks form from the earth's surface. I was quite interested with the different types of rocks there are.
ReplyDeleteThe creation of the Earth is closely tied to the formation of the solar system about five billion years ago. The solar system condensed from a huge cloud of gas and dust, with the Sun forming as part of the cloud collapsed in on itself under the influence of gravity to the point where nuclear fusion could begin. The Sun’s gravitational field attracted large amounts of material, which formed a disc-shaped structure around it, known as an accretion disc. The Earth, like the other planets, was created around 4.54 billion years ago when some of the material from this disc came together to form a spherical body. At some point early in its history, it is thought that a smaller planet collided with this body, increasing its size and resulting in the formation of the Moon.
