What protects Earth from solar winds?

• The poles

• The moon's gravity

• The magnetic field and the atmosphere

• The tidal range

The hottest layer of the sun is the ______

• convective zone

• radiative zone

• core

• chromosphere

Dark areas on the sun's surface where plasma is cooler than the plasma around it. These areas give off less light.

• prominences

• radiation zones

• solar flares

• sunspots

Sometimes loops in sunspot regions suddenly connect, releasing large amounts of magnetic energy which heats the plasma to millions of degrees causing it to erupt into space. This eruption is called ___________ .

• solar flares

• prominences

• nuclear fusion

• the corona
