The Earth's gravitational field is important primarily because it keeps the Earth in orbit around the Sun, which sustains life. Without gravity, life would cease to exist.
Is earth the only planet you can live on?
Yes because it is only planet with right amount of heat from the sun and hence sustains life.
Why do you live in a house?
We live on earth because it is the only planet that can support life. Other planets are too far from the sun whereas others such as mercury are too close to the sun. Earth has just the right stable temperature for human, plant and animal life.
What are all the ways the sun may be defined?
The Sun is the star around which Earth and the other bodies in the Solar System orbit. It is an important source of light and heat for life on Earth.
How does the sun sustains life?
The sun generates enormous amounts of heat which then travels to the earth, raising the temperature of the earth to that which can sustain life which is at an average of 15oC on the Earth's surface. The light generated by the sun provides energy for the reaction of photosynthesis without which sugars cannot be synthesized, and therefore food and consequently life cannot exist. The immense mass of the sun causes it to attract comets, giant meteoroids, larger asteroids etc which can be on a collision course with the earth, thereby reducing our chances of being wiped out like the dinosaurs (who were killed by odds one in a million of a meteoroid of that size crashing into the Earth) Hope this helps!
What are two ways the sun can hurt life on earth?
It can burn things and dump giant rasins on things and crush them
What is primary source of light?
The primary source of light on Earth is the Sun. It emits light and heat energy through a process called nuclear fusion in its core. This light sustains life on our planet and allows for photosynthesis to occur in plants.
How does the sun affect life on earth?
Without the sun there would be no life on earth because the sun gives heat and life energy that if it is missing, Earth would be totally freezing and without life. The 5 branches of living things cannot survive without the sun.
Is the sun bad for the earth?

Could there be life on earth without the sun?
