The planet Earth is part of a dynamic solar system, interacting with a variety of celestial
bodies like asteroids, meteorites, comets, and the moon. The origin of the Earth along
its entire system has been researched for hundreds of years. Various scholars have
developed different theories and arguments on how the planet Earth evolved and changed
over time. In this chapter you will learn about the Earth. You will focus on its origin,
position in the solar system, shape, and size. The competencies developed will enable

The Earth is the only known planet in the solar system that supports life. Its surface is
made up of land and water bodies. The evolution of the Earth can be traced through
various assumption, including both theories and hypotheses, which explain about
the origin of the universe. A number of ideas, principles, and assumptions have been
developed by various scholars to trace the origin of the universe from which the planet

Earth is found. These assumptions have examined various processes through which the
universe, galaxies, stars, and planets were formed, and the changes that are still taking
place over time (Figure 2.1).
