hurricanes form over water, where it is difficult to observe them.

forecasters must consider a large number of variables that affect the path of the storm.

Explanation:

Btw this is the correct answer, and the other person that said this answer got a low rating...they got it right though.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
