Upto ordinary heights, the change in the distance of a projectile from the centre of earth is negligible compared to the radius of earth.
Hence, the projectile moves under a nearly uniform gravitational force and the path is parabolic. But for the projectiles moving to a large height, the gravitational force decreases quite decreasing variable force, the path of the projectile becomes elliptical.
