Answer 3

Dawn refers to the twilight before sunrise. It is recognized by the presence of weak sunlight, while the sun itself is still below the horizon. There are also more technical definitions of dawn, including the following:

Astronomical dawn  

the moment after which the sky is no longer completely dark, formally defined as the time at which the sun is 18 degrees below the horizon in the morning. [1]

Nautical dawn

the time at which there is just enough sunlight for the horizon and some objects to be distinguishable, formally defined as the time at which the sun is 12 degrees below the horizon in the morning. [1]

Civil dawn  

that time at which there is enough light for objects to be distinguishable and that outdoor activities can commence, formally defined as the time at which the sun is 6 degrees below the horizon in the morning. [1]

Dawn should not be confused with sunrise, which is the moment when the leading edge of the sun itself appears above the horizon.

so breaking dawn is when dawn first starts to come over the horizon. Breaking dawn is going to be an awesome book!!!! I think it refers to the time Bella finally gets changed into a vampire.
