Comparing Venus, Earth, and Mars Below is a list of some information about the three planets, Mercury, Venus, and Earth. Liquid water. Gaia HypothesisP. Earth is similar to Mars because we know that life is possible The sun is the source of energy for most of earth's processes. The internal structure of living organisms represents order. But, the largest stars, known as hypergiants, have lifetimes of only a few million years. Third Rock: There's a reason we've found life on Earth and nowhere else. This would have happened over a maximum period of 200 or 300 million years after the first microorganisms, and would have caused the early extinction . According to Tom, there are three main ways in which the Moon impacts on life: time, tides and light. 6 THINGS THAT MAKE LIFE ON EARTH POSSIBLE. interconnected independent factors connected to tectonics dependent on the Sun The sun keeps the engine running for the water cycle: evaporationcloud formationprecipitation.

Our atmosphere contains 21% oxygen, which is necessary for us to breathe, 78% nitrogen, SCORPION-xisa [38] 2 years ago 5 0 Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. Planet" because it is the only known planet that has large amounts Without sun, these wouldnt work. More recently, the terms Gaian science or Gaian theory have become more common than the original Gaia hypothesis because of modifications in response to criticisms and expansion of our scientific understanding. The fossil record informs us that existence on the planet has lasted a minimum of 3. Importance of Liquid Water. The Earth has a suitable climate for the existence of all forms of life because of moderate amount of carbon dioxide, which is the driving factor for the survival of life forms. blasting their planets with bursts of radiation.
