Earth is the third planet from the SUN and it is slightly larger than the size of Venus. The earth is seen as a tiny planet in the vast universe, which contains billions of stars, planets and moon as well as huge areas of space containing other smaller particles. There is no definite proof of how ancient events such as the earth’s formation took place.

FORMATION OF THE EARTH

The earth is thought to have formed about 4600 million years ago and it has been constantly changing and developing ever since. It probably started as a huge, swirling cloud of dust and gases. Over time, this cloud began to shrink and become solid. Heavy iron-rich minerals collected at the growing planet, eventually creating a core of iron.

It is believed by scientists that, the oceans where formed from huge rains in the early days due to periodic explosions of volcanos causing melted ice beds from the glaciers and deformation of land surface. During these explosion, gases such as methane, hydrogen and ammonia rose from these volcanos caused by the expansion of gases, shockwaves, heat and light producing chemical and nuclear reactions. Icy comets and rocky asteroids are believed to have landed on earth during those periodic explosions of volcanos from different galaxies.

THE CURRENT WORLD MAP AND ITS CONTINENTS
Here is the current world map indicating interval longitudes in 30 increment from the Equator moving both North and South.

The latter map indicates the different continents in a smaller scale. On the next paragraphs, we’ll discuss about the formation of early life on Earth.

THE FORMATION OF EARLY LIFE IN OCEAN
It is believe that, around 3,500 million years ago, simple life-forms generated from chemical composites, churning chemical waste, hydrogen and oxygen producing low levels of carbon dioxide and energy into the atmospheres. These simple life-form organisms ranges from green-like plants such as water lilies, coral ridge life organisms and fresh water organisms continue to produce oxygen and carbon dioxides into the atmosphere. The atmosphere produces layers of cloud barriers preventing most of the sun’s ultraviolet rays from reaching the earth’s planet surface.

THE FORMATION OF THE SHAPE OF THE CONTINENTS
After the formation of the Earth, the landmasses appeared. The earth’s turbulence coupled with the circulation and explosion of the volcanoes flowing into the oceans created movements and splits of landmasses and body of water forming continents. Depending on the size of these body of water, they are classified as oceans, seas and rivers and lakes.

Dates associated with the formation landmasses were 250 million years and after the splits, there was just one giant landmass called PANGAEA. PANGAEA began splitting around 225 million years ago forming what are called today as continents.

The shapes of the Earth splits ranging back 250 million years ago.
