It may also determine which ascending impulses are to be blocked and which are allowed to pass to other centres in the brain. The olivocochlear bundl

A Day on Earth - by StudyJams
As the Earth rotates, light from the sun hits different parts, giving us day and night.  During its orbit, the Earth's tilt on its axis also causes two hemispheres to be different distances from the sun, and that gives us seasons.  Learn more about the Earth's rotation with this cartoon animation from StudyJams.  A short, self-checking quiz is also included with this link.
