Earth information When an object the size of Mars crashed into the newly formed planet Earth around 4.5 billion years ago, it knocked our planet over and left it tilted at an angle. Earth's axis is the imaginary red line. Earth's Axis Is Imaginary In astronomy, an axis refers to the imaginary line that an object, usually a planet, rotates around. Earth's rotational axis is an imaginary straight line that runs through the North and South Pole. In our illustrations, Earth's axis is drawn as a straight red line. Ever since the impact around 4.5 billion years ago, Earth has been orbiting the Sun at a slant. This slant is the axial tilt, also called obliquity. Earth's obliquity angle is measured from the imaginary line that runs perpendicular to another imaginary line; Earth's ecliptic plane or orbital plane (see illustration). At the moment, Earth's obliquity is about 23.4 degrees and decreasing. We say 'at the moment' be...

History of Earth ________________ By _ earth information The history of Earth concerns the development of planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of Earth's past. The age of the Earth is approximately one-third of the age of the universe. An immense amount of geologicalchange has occurred in that timespan, accompanied by the emergence of life and its subsequent evolution. Earth formed around 4.54 billion years ago byaccretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost nooxygen and so would not have supported known forms of life. Much of the Earth was molten because of frequent collisions with other bodies which led to extreme volcanism. A giant impact collision wit...
