Lines of Latitude are called parallels because the lines parallel, or run in the same direction as the equator. The equator is the imaginary line that is as far away from the North Pole as it is from the South Pole. Lines of Longitude intersect the equator at right angles but end at the North and the South Poles.

Yes...acceleration is the rate of change of velocity with time.....therefore when velocity is zero..definitely acceleration is zero. This is not exactly true; at an instant in time the acceleration can be non-zero while the velocity is zero. However, this would change the velocity to non-zero after any amount of time. An example of this is when you throw a ball into the air: at it's highest point, the velocity is zero (it changes from going upward to going downward, passing through zero for an instant). However the acceleration is downward the entire time.
