It's due to the earth's gravitational pull or force....

Becaus of Gravity my friend.
Gravitation is a phenomenon through which all objects attract each other. Modern physics describes gravitation using the general theory of relativity, but the much simpler Newton's law of universal gravitation provides an excellent approximation in many cases.
There is no Gravity on the Moon.... did you know that? So if you throw something upwards there, it will NEVER come back to the ground...

You did not think about this while shiting. Its bcoz of gravitational force. it is the phenomena in which the earth pulls all the objects towards itself, even we stand on the ground bcoz of gravity. if you want that the things thrown upwards do not come back, you just have to throw the objects with a force of 11.2km/s. simple isnt it?

Because of earth gravitational force. But if thrown with a high speed it will not return to ground.(speed must be sufficient to reach the space where the gravitational force is nil.)

It is simply due to gravitational pull.and may be the force with which ball thrown up may be less than the force of gravity, and once ball is thrown up word you have no control over its speed, force etc.

this is bcoz of gravitational force bteween d object n d earth.
although if an object is thrown wid more than a speed of about 11.2 km/s it can escape d earth's gravitational field n can be established in an orbit around d earth (satellite)

every one telling that gravity.Just imagine ,think in my way Universe, it formed due to big bang theory.its an big explotion forming no of stars this stars combine to form a galaxy .galaxy has many no stars sun it is one of the biggest star in our galaxy and it is center of our galaxy .yhe force the caused when exploding made the galaxies to spin around itself example(if u spin a ball it will rotate for some time and stop.same thing happens here our galaxy will spin around for some crores of year .being sun is our center it also spins around itself (example fill bucket full of water and put your hand in the middle and make it to rotate the water u will see the twister like in center it will suck everything while rotating).same as this princple sun is trying to pull towards it and this cause our planet to rotate the sun.revolving is the same princple as the ball rotating, for planets.every planents has its own gravity force as we had grown in earth we manage or tend to devolope oppsite or attraction force .if we had grown in mars we would devolope to manage attraction force present in the mars or either in moon moon. earth has three layers magma in center and rock deposits and sands rock deposits as magma is the semi solid which is nearly 10000 degree celcius causes these rock deposits to float and the magma because of its heat devolops pressure and it tends rotate the magma core if they tend to find any weak layer it erupts as valcano.may be this can also cause gravity

bcuz of the gravitional force or pull of the earth
