The changing alignment of the Earth, the Moon, and the Sun impacts conditions on Earth. Earth rotation, revolution, and tilt influence the change from day to night, the seasons, and the passing of a year. The gravitational pull on the Earth from the Sun and the moon influences the changing ocean tides. The alignment of the Earth, the Moon, and the Sun also create lunar and solar eclipses that can be seen from Earth. Take a look at the picture below. This is a picture of Earth rising that was taken from the space shuttle in orbit around the moon- remember, perspective is everything!
