People in the past did not know what the Earth looked like because the technology was not advanced. Why do some people think the Earth is flat? The Earth is the only planet where life lives, and the presence of water and air necessary for the survival of life characterizes it. Subsequently, the impact of the asteroid reduced the Earth’s temperature, resulting in the formation of a primitive sea, and over time, life in the primitive sea (Alden, 2019). The impact of many asteroids increased the size and mass of the Earth, and the Earth became a sea of magma. Several materials, such as dust, were then combined around the Sun’s orbit to create a primitive planet, an asteroid. What is the history and characteristics of the Earth?įirst, nebulae in the solar system were formed, and these nebulae rotated and contracted to form the primitive Sun.
