How does moon affect life on Earth? Earth's amazing gaseous atmosphere is responsible for making life possible on this, the third planet from the Sun. All life need some kind of food, water, the best atmosphere and temperature. Over a billion-years, hydrogen converted to helium at the core of the sun where the temperature is an unbelievable 15 millionC. The researchers found a distinct nitrogen isotopic signature in the dust that bathed the inner protoplanets within about 300,000 years of the formation of the solar system. This has traditionally been connected to Earth's proximity to the sun allowing liquid water to exist on its sur. Plus, the moon causes the tides, and some biologists think life began in tidal pools.

Nearly a decade ago, Martins and colleagues from the University of Kent in the U.K. simulated comet impacts onto a planetary surface. This property seems necessary to life in that all organisms grow or develop during at least some periods of their life cycles. According to Tom, there are three main ways in which the Moon impacts on life: time, tides and light. A new study has proposed our planet's richness in these vital materials is a result of being hit by a . Water Our Planets atmosphere contains water. A It is at a perfect distance from the Sun.
