When there was only water on Earth

Earth is an active geatomosphere world that has been transformed many times in various ways. It has been found that the continents have made their appearance relatively late on the planet and for a long time that lasted about 1.5 billion years, the continents have undergone several stages of shaping, joining together and segregation until the situation in which we know today .

The Oregon University team has conducted a new study on the geological evolution of our planet. According to the current theory, Earth was created about 4.5 billion years ago and as the new study states for about two billion years it was an aquatic world.

The Earth’s mantle was very warm and soft and therefore could not support the presence of land and much more the existence of mountain ranges. But at some point the mantle’s temperature was reduced allowing the first pieces of land to emerge from the sea. The collisions of these first pieces of land between them caused the creation of the first mountain ranges and plateaus on the planet.

According to the new study, the first pieces of land appeared 2.4 billion years ago and 300 million years after these pieces joined together to form the world’s first continent named Kenorland.

The presence of the continent caused a series of geathemospheric processes that led to the removal of large amounts of carbon dioxide from the atmosphere and the simultaneous increase in oxygen levels. This opened the way for more complex forms of life to be made on the planet than the bacteria that existed until then in the water.

The first algae, the first plants and the first fungi were made to appear, and then all went their way to creating new continents, but also to blossom life on the planet
