World history

Start of creation

Exactly when the world is created? There is no rocking start, so it is not right to say. However, it is believed that after the collapse of the solar system almost 100 million years, the result of a clash was the result of the earth. From today 4.54 billion years ago, the Earth named planet gets shape, a center of iron and an atmosphere.

Earth-Moon Clash

Earth's collision with an asteroid in the shape of a fairly good Mars named "Theia" The Earth is fairly slow but the atmosphere is destroyed and the destruction of the asteroid disappears. The ruins of it are made from the moon.

Molten lava sea

The world became hot due to the collision with Thier. Around the ocean going to melt lava. As the condition of Venus is now, then the condition of the Earth was the same. It is slowly cooling down the earth, the lava bundles are made from rock and water and the first sea in the earth. At the time, the world's oldest mineral, made of zircon They are approximately 4.4 billion years old.

First continent

Now the different continents of the world are sitting on top of all the tectonic plates. The primitive tectonic plate but was too small. Many gold and silver precious metals are available in them. The first continent was created almost 3.8 billion years ago.

The first breath of life

About 3.5 billion years ago, photosynthesis comes from the first oxygen. The first oxygen comes from stone-borne cyanobacteria or green leafy shawl. But it did not really do anything like that. Due to the presence of this oxygen, some bacteria die that can not tolerate the presence of oxygen. Thus, 2.4 billion years ago, oxygen was greatly increased in the world, which is called "Great Oxygenation Crisis".

One billion years in silence

After the first continent was created, there was not much in the world for a billion years. It's been a long time. The continents were stuck in a traffic jam - that's not a movement. At that time there was no improvement of life.

The Great Continent

One of the major continents is Pangea. Here the origin of the dinosaurs will occur. The other is Eurasia. Still, the researchers can find out on different mountains, just how many different regions of the world were connected together to create these huge continents.

Terrible winter

Around 750 million years ago, a great continent was separated from others. During this time the world was completely cold and transformed into a huge ice pellets. At this time the glaciers were covered with earthquakes. Even in the equatorial region there was glacier.

Life explosion

650 million years ago, the atmosphere began to grow again in oxygen and at this time different organisms are emerging. Along with unitary species, multicellular animals come together. During this time period, hunting and hunting emerge.

Extinction of animals

The biggest extinction event in the history of the world happened today in the Permian period 252 million years ago. Nearly 90 percent of the organisms are extinct in just 60 thousand years. 66 million years ago the cretaceous period was extinct, 85 percent of the organisms including dinosaurs. The reason for the extinction of the Permian period was due to a huge volcanic eruption in Siberia. Due to climate change, extinction has also been observed. 450 million years ago, the erosion caused a major ice age to 75 percent of the organism.
