Hello classmates! I want to give a brief explanation about the solar system. The solar system has eight planets the names of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune, Pluto. In the solar system, only the Earth's planet is alive. Earth has a lot of mines and reserves for example oil, gas, uranium, and so on. Earth has an ozone gas that protect ultraviolet rays from reaching the earth. Water is a source of life and humans and animals need it to live. The astronauts on the Mars planet saw similar earth for human life. Humans destroy the earth with unconscious activity.
