Why is there 12 hours of daylight all year at Quito?

I think it's because it's on the equator, but I don't really get it

    You're right.

    The way the earth tilts, the sun appears to be farthest north when it's over the Tropic of Cancer. It's seen as farthest south when it's over the Tropic of Capricorn. This means that the sun appears near or over the Equator all year long.

    I used to demonstrate this to my classes by using a flashlight to represent the sun and approximating the tilt of the earth with a globe.

    This site has more information.
