Well the Earth is round because of gravity. Everything has gravity, even a pebble, however the force is so weak compared to earths gravity it is not effective.
When bits if rock started joining together 5 and a half billion years ago, they started forming a large piece of rock. As this got over a certain size, its own gravity caused it to become a sphere, and that's how its got it's basic shape.
However the earth has also been shaped by meteors hitting the surface, tectonic movement (earthquakes) and (mainly) volcanoes, which create a new surface when the lava cools down.
That's a very brief explanation, sorry if it isn't good enough.
