Life is sustained on Earth, from a scientific stand point it is a delicate balance of nature. The right amount of heat and cold, sun and dark, water and dryness, the changing of the seasons, the rotation of the earth, there are a million different tiny aspects that make life possible and all of those things have to line up perfectly for it to be possible.
From a Christian stand point God created the above laws of nature thereby sustaining life on Earth. The delicate balance is proof of a creator.

∙ 14y agoGenerally by being in the right place at the right time.
The earth occupies a place in the solar system generally referred to as the "Goldilocks" zone, e.g. near enough to the sun to capitalize on the heat from the sun (planets further away are much cooler) but not near enough to the sun that the atmosphere is burned off.
Besides the right place, we also need air to breathe, and the earth has an atmosphere (consisting of primarily nitrogen and oxygen).
We have water on the planet, which life, as we know it, require to exists.
We have a magnetic field which shields us from harmful radiation and which is created by the molten, active iron core.
This hot molten iron core is also responsible for plate tectonics. Without the moving continental plates which are constantly recycled, we would probably have not had the length of time with stable, moderately warm temperatures required for life to take hold.
Therefore, the answer is not a simple one item, but a number of fortune events.

Soils sustain life by using organic material for nutreints.
What is everything that is alive on earth made of?
Earth is only made of rock and has gravity.
What is structure 3 and how does it help sustain life?

What kind or energy drives all the processes important to life on earth?
If you mean living processes, then the answer is Sunlight. If you mean geological processes, then the answer is decay (nuclear fission) of radioactive isotopes in the Earth's core and Sunlight. If you mean tidal processes, then the answer is kinetic (rotational) energy transfer.
What is the difference between the earth and the stars?
Stars are suns and cannot sustain life. Earth is well, earth, and it CAN sustain life.
What must you do to sustain life on earth?
we can sustain life on earth if we keep on recycling and pick up rubbish.
What three interconnected factors sustain life on earth?
Life on Earth is sustained through the flow of energy from the sun, the cycle of matter through the biosphere, and gravity. These factors are essential to all biotic processes.
Is life on earth possible?
While Earth can no doubt sustain life in the case of humans and every animal alive to date, it is still a question as to whether earth can sustain life or not.
What is the difference between earth and a star?
star is a huge mass of gas, where as earth is a planet
What are the three features of Earth that allows it to sustain life?
In order for earth to sustain life it has the magnetic field, plate tectonics, and active volcanoes.
What are the features of the earth are necessary to sustain life?
Apart from water, you need oxygen in the air to sustain life on earth. With these two indispensable features, both mankind,animals and botanical reserves sustain life on this planet.
How does gravity make satellites orbit the earth?
Gravity provides the centripetal force to sustain orbits, F= mGM/r2
What must a planet have to sustain life?
To sustain life, a planet must have oxygen and a variety of gases, plant life, strong enough gravity　ａｎｄ　ｅｎｏｕｇｈ　ｃｌｅａｎ　ｗａｔｅｒ．
What planet is known to sustain life?
No planet except the planet Earth is known to sustain life till date.
What is the planet that could not sustain human life?
Earth is the only planet in our solar system that can sustain human life.
What are 3 processes that sustain life on earth?
The flow of high quality energy, the cycling of matter and gravity
