How Does Life Giving Cycles Make Life Favorable on Earth?

When we hear the word Earth, the first thing that comes to our mind is that a terrestrial planet where there exists from microorganisms to highly sophisticated and intelligent human beings. Factors that are responsible for the current life on Earth.

The Earth and the Sun are equally important because without the heat and light of the Sun, the Earth would have been a lifeless ball of ice-wrapped rocks. It regulates the temperature, weather patterns of water bodies and provides energy to plant growth. The distance of the Earth from the Sun makes it a true reason for life because it receives the right amount of heat and light to allow life to form and support it.

Earth is the only planet that uses sunlight as a source of energy. That energy is used by living things to convert elements into a useful form. A plant uses the energy provided by the sun to drive photosynthesis and grow food. As a by-product, oxygen is released which we all use as our own energy source.

Importance of Earth’s Atmosphere

These are layers of gases around the Earth including the exosphere, thermosphere, mesosphere, stratosphere and troposphere. Air content and favorable atmospheric pressure also supported the lives of most creatures. The air content of carbon dioxide on Earth is less than that of planets like Venus and Mars. Therefore, the low amount of carbon dioxide helps in reducing the temperature of the earth and is absorbed by the plants during photosynthesis to produce oxygen.

Favourable Climatic Condition

Due to the moderate amount of carbon dioxide in the Earth, there is a suitable climate for the existence of all forms of life, which is necessary for the existence of life forms.


Water is very important for life because it contains oxygen necessary for life and allows life-giving molecules to move freely. It constantly changes its form through the water cycle. The process by which water continuously changes its form and spreads between the oceans, the atmosphere, and the land is known as the water cycle.

The major sources of freshwater are rivers, ponds, waterfalls and glaciers. Marine bodies and oceans contain saline water. The water of the oceans is salt or saline because it contains large amounts of dissolved salts. Most salt is sodium chloride or common table salt that we eat. Three-fourths of the Earth is covered with water. Only 3% is fresh water consisting of ice-caps, ground water and fresh water lakes.

Force of Attraction (Earth’s Gravitational Force)

Why does the water flow from the top down, why not float in the air; why don’t we float in the air and walk on the surface. The gravitational force of the Sun keeps our planet orbiting the Sun and the Earth holds firmly to all forms of life from topography through its gravitational pull.

Thus, Earth is the only planet that saves liquid water on its surface, which develops life forms through photosynthesis by taking energy from the Sun. It has a unique surface that is neither too hot nor too cold for the occurrence of complex biochemical processes. Read More…

Hi ! I am Ashok Sharma. I studied at Maharishi Dayanand University, Rohtak, Haryana, India. Reading and writing have been my hobbies since childhood. Do not try to plan everything in the very last detail. Just create it, publish it and get feed back from you. But if you really want to grow then you will need points of leverage and most of them come from knowing people. Change is going to be continuous. It is a beginning, not an end. It will be my constant endeavor to thank the readers for their love, guidance and interest that I can do better than ever……..
