The top layer of the earth is called the crust, this is made up of tectonic plates which shift and move in direction, it is the collisions and abrasions caused by the friction forces eroding the edges of these plates which push us the crust, and pour out lava and other rock causing the mountain ranges to form, this process continually happens and over millions of years has changed the surface of the planet, created vast mountains and continents. The lower spaces are those which the oceans fill, and the higher regions above sea are the continents.
At convergent boundaries magma is formed where water from a subducting plate acts as a flux to lower the melting temperature of the adjacent mantle rock.
I seen someone yelling doing the chicken dance around the room they were looking at the camera with the chicken mask it was the funniest thing I ever seen
