Q

How do scientists use sunspots to study solar weather?

A

They determine the possibility and chance of solar activity by amount of sunspots.

17
Q

Describe how energy is released in the sun’s core and is transferred through each layer to earth.

A

Nuclear fusion happens in the core, it radiates through the radiative zone, the convective zone transfers it outwards, the energy radiates through the photosphere, it radiates through the chromosphere, and finally radiates through the outermost layer the corona.
