Match the layer of the sun to an aspect of that layer

Draggable item		Corresponding Item
Chromosphere		Energy is released by fusion
corona		Energy is moved by photons being released, reabsorbed, and released again
Radiative zone		Energy is carried by moving atoms rather than photons
Core		transition layer where gases move from being transparent to opaque
Convection zone		thin layer with strong red-emission lines that can be seen during an eclipse
photosphere		third hottest layer of the sun that has lowest amount of energy because of its low density

What is your best explanation of a Neutrino?

Watch the following video. What questions do you have?

What are neutrinos?

Massive atomic particles

Nearly massless subatomic particles that rarely interact with matter

Large molecules found in space

Electrons with special properties

What makes neutrinos unique among subatomic particles?

They have an extremely large mass

They carry a strong electric charge

They can pass through matter with very little interaction

They are always stationary

Why are neutrinos important for understanding solar processes? A) B) They provide insights into nuclear reactions happening in the sun's core C) D) They measure the sun's rotation speed

They directly reveal the temperature of the sun's surface

They provide insights into nuclear reactions happening in the sun's core

They show the sun's magnetic field strength

They measure the sun's rotation speed

What happens in each layer of the sun
how fusion works
what is hydrostatic equilibrium?
What is the relationship between temperature and pressure?
how e=mc^2 works in terms of powering the sun
What is a neutrino?

I've got this
I'm fuzzy
Im so confused.
