Born of Earth till The Present Earth

Watched Discovery channel and came across this interesting programme, if not mistaken is "The born of Earth". It talks about how Earth was born and what happen after She was born till present Earth that we know today.

4.5 Billion years ago, Earth was collide with a planet of a size of Mars. Due to the massive speed and destructive collide, both planet joined as one. Then, Hydrogen gas and Oxygen gas combined to form water which covers the whole planet of earth, leaving the land under the sea.

Land was then born due to the eruption of volcano undersea. Volcano are active at the time cuz of the collision happened, the centre earth core gives a high pressure of magma to erupt. The magma then turns to solid and became land. This is when the 1st plate tectonics happened. Layers of laters of land were collide and covers each other to form a huge continent - Rohana ( I forgot wat's the term, but it sounds like this, will update this again.) Specialist found the land content of Rohana from U.S. + Afrika + Grand Canyon. Can you imagine how big is this continent?

Around 300mil ago, a larger continent was formed - Pangaea through the pushes of 2 or more continents together.

At that time, Sahara is not the largest dessert found on earth, there is a larger one, the father of sahara, located at the higest region of Pangaea. There were no life survive then Pangaea was created + no clouds can ever reach that height, therefore no rain.

Later on, Pangaea was then break into different continents and the land spreads a cross earth. Sea water were then cover the lands that are at lower level are now called the Atlantice Ocean. Angel Falls - highest waterfall was also created after the break apart of the largest continent, Pangaea.

90 million years ago, specialist found out that Grand Canyon were submerged under sea water b4. This is because of the move of plates at North America.

Specialist also found out that there are corals live below deep sea, which is an abnormal phenomenon. Specialist can only say is due to the melting of ice causes by the climate change during Ice age. During Ice age, 1/3 of world is covered with ice. Ice age occurs every few thousand years. Every ice age that happens, significant life changes after/during ice age too.

End of the programme, will our planet change again? will continents collide with each other to form a massive continent again? Specialist saying that at Alantic - have the most active volcano on earth - has begin to born new islands due to volcano eruption under the sea. Mount Augustine, stated the youngest island on earth - 12-14 months old, and this volcano is still very active, It may continue to grow again. Specialist also says that they don't know whether there is any lifeform exist in this world to face the next plate tectonics which will happen in a million years time.
