• Make a 25 cm high mountain with some soil. A plant uses the energy provided by the sun to drive photosynthesis and provide food to grow. NASA/Apollo 17 crew; taken by either Harrison Schmitt or Ron Evans.

However, they are roughly 1000 times smaller than the smallest bacteria on Earth, so don't resemble any life thought to be possible. The ocean bodies and the seas contain salty water. That energy is used to convert elements, by living things, into a useable form. In this write-up, we discussed the factors that are responsible for the existing life on the Earth. State Three Factors That Have Made Life Possible On Earth. The possibility of life on Mars is a subject of huge interest in astrobiology due to its proximity and similarities to Earth.To date, no proof has been found of past or present life on Mars.Cumulative evidence shows that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms. As a by-product, oxygen is released which we then use as an energy source of our own.As we know that the Sun is the primary source of energy to the Earth, but the only planet that optimises the amount of heat and light which is necessary for the life process. In planetary science, the “Goldilocks zone” is the terminology for the band around a sun where temperatures are neither too hot nor too cold for liquid water to exist.If it was too close, the Earth would be too hot. how was the earths core discovered. Some are illustrated by the samples shown here. But you know what, if get more that amount of what we getting will not give more Vitamin D but causes serious issues on our skin and health.The major sources of fresh water are the rivers, ponds, springs and glaciers. The force of gravity doesn’t just keep us anchored to the ground, but also affects our biological system.The Earth and the Sun are equally important because without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rocks. Why Does Earth Have An Atmosphere Live Science. Only about 1% of the ultraviolet radiation that the Sun sends to Earth actually reaches the surface. The air content of carbon dioxide on the Earth is less than that of planets like Venus and Mars. seismic waves from a large earthquake that weren't passing though center of earth… 97.3% water is saline or salty in oceans and seas, 3% is fresh water that consists ice-cap, ground water, fresh water lakes, inland and salt lakes. There are many factors which make Earth suitable for life are discussed below:Water is very important for life because it contains the oxygen needed for life and allows life-providing molecules to move around easily. It regulates the temperature of water bodies, weather patterns and provides energy to the growth of plants. What Makes Earth So Perfect For Life Live Science. Optimistic Facts And Charts That Show The World Is Getting Much. Timeline The Evolution Of Life New Scientist. Things that make life on Earth possible: The Blue Marble – Earth as seen by Apollo 17 in 1972. Mars Pared To Earth Universe Today. The water of the oceans is salt or saline as it contains a large amount of dissolved salts. If this was the case, life on Earth would not be possible.The Earth receives enough energy from the Sun to allow water to exist as a liquid on the surface.Some type galaxies are too compact (stars so close to each other). It would lose all the oceans. This image, with the official NASA designation AS17-148-22727, became known as “The Blue … Plus, the moon causes the tides, and some biologists think life began in tidal pools. it avoid the galaxy’s perilous inner regions. Most of the salt is sodium chloride or the common table salt that we eat. Life emerged some 700 million years later, or about 3.8 billion years ago. There are five additional planets in our solar system, each as barren and dead as the last -- which makes Goldilocks seem downright amiable by comparison. Mars, although it can reach 25°c, is usually freezing and can be as cold as -140°c, a temperature which would freeze blood and water. One group of students designed an experiment to demonstrate the interaction between Earth spheres.
A gravitational field, a magnetic field that protects incoming comets and astroids, and the ozone layer that blocks harmful UV radiation.
