What makes a planet in a habitable zone able to sustain life? The suns rays sustains all existence on the planet, it shines upon us, warms our planet, the seas, the climate, it influences the weather, it causes dry periods and ice ages, it causes wind, which blows within the earth and determines our weather. The environment content and favourable atmospheric pressure also supported existence on most creatures. 15 Goldilocks Factors That Allow Life on Earth to Exist A look at 15 factors that allow life to thrive on Earth. Video advice: What a planet needs to sustain life. But so far, scientists have discovered the oldest evidence of life, which dates back to a period of 3.5 billion years. To maintain order and survive, a living organism must have a continual source of energy like food or chemical interactions with the environment. earth is the only planet with life. Our atmosphere contains water vapor which helps to moderate our daily temperatures. The idea of co-evolution of biology and the physical environment where each influences the other was suggested as early as the mid-1700s, but never as strongly as Gaia, which claims the power of biology to control the nonliving environment. And obviously, the impact energy is going to be enough to break molecular bonds and create more complex molecules, she says. Exactly why is Earth stand out? 3 reasons Earth is unique 1) only known planet that has liquid water on the surface 2) an atmosphere that contains a large portion of oxygen 3) only planet known to suppot lifr Why do scientist study the characteristics that make life on Earth possible?

There would be no other form of life. carbon dioxide is needed by. Then there's our lack of understanding of how life enabled the big jump from just having prebiotic chemistry to actually having biology, says Martins. The system consists of the land, oceans, atmosphere and poles. And that organic matter was brought to Earth early in Earths history, she says. Our atmosphere contains water vapor which helps to moderate our daily temperatures. Martins says once Earth cooled enough to harbor liquid water on its surface, our planet have hit a critical stage where life could begin to form. But, the largest stars, known as hypergiants, have lifetimes of only a few million years. C It is very close to Mars. Those are the brightest electromagnetic occasions recognized to exist in the World. How many habitable planets are there? We are confident there is no possibility of existence in the world, stated Durch planetary researcher Sara Seager. Nutrients, atoms and molecules, are the necessities for building living cells (Bennett, 2012, p. 510). (Hint: Constraints for example i1 = x1 + 5 20 are extremely needed. The moon: The Earth has a slight tilt and teeters like a top as it spins, which can cause drastic shifts in climate over the course of thousands of years. When we heard the term Earth, the first things came up in our mind that a terrestrial planet where all forms of life: from basic living micro-organisms to highly sophisticated and intelligent human beings exists. This helps to build an overall suitable temperature condition, by avoiding extreme hot or extreme cold,conditions. How does that work together? Much less than does light, at least in our current evolutionary era, but many theorize that geothermal energy (heat from the earth's core) was the first source of energy to power life. Life depends on this for moving the chemicals it needs for growth, maintenance and reproduction: 1)The habitable zone: Earth is at the right distance from the Sun to have liquid water on its surface, and for the atmosphere to be at a reasonable temperature for life to occur. I'm not so sure if we will ever know exactly how life started on Earth and when, says Martins. there is gravity and loads of nutrients.
