The solar eclipse on Sunday is considered a hybrid because it starts out as an annular solar eclipse and transitions into a total solar eclipse. 

An annular solar eclipse is when the moon is too small in the sky to cover the entire disk of the sun.  

Below is an example of an annular eclipse from NASA

At the bottom of the picture you can see the sun peaking out below the moon.  

On Sunday morning, according to Sky & Telescope, the solar eclipse switches from annular to total because of the way the shadow moves across the curvature of the Earth. 

"The shadow's footprint is also moving closer to the Moon due to Earth's curvature. So the appearance switches to and remains a total eclipse." says Sky & Telescope contributor Kelly Beatty.

A total solar eclipse is when the shadow of the moon completely blocks out the disk of the sun. Only the corona, the fiery outer layer of the sun can be seen around the disk of the moon. 

The moon and sun must be in perfect alignment, with the moon just the right distance from the Earth to block the entire disk of the sun.

Sunday's eclipse can be seen live from Africa and over the central Atlantic Ocean.
