IN WHAT WAY DOES THE SUN SUPPORT ALL LIFE ON EARTH?

INDIRECTLY, MOST OF THE ENERGY ON EARTH COMES FROM THE SUN. WITHOUT THE SUN, WE COULD NOT MAINTAIN OUR AVERAGE SURFACE TEMPERATURE.

WHICH TWO ELEMENTS MAKE UP THE SUN ALMOST IN ENTIRETY?

HYDROGEN AND HELIUM

WHICH PROCESS IS THE SOURCE OF HEAT IN THE SUN AND WHERE DOES IT TAKE PLACE?

NUCLEAR FUSION IN THE CORE – HYDROGEN IS FUSED TO HELIUM

WHY WOULD HUMAN ASTRONAUTS ON A TRI TO MARS NEED TO BE CONCERNED ABOUT SOLAR WIND?

IF WERE INTENSE ENOUGH, IT COULD BE FATAL.

WHAT IS SOLAR WIND?

CHARGED PARTICLES KICKED OUT FROM THE SUN DURING CORONAL MASS EJECTIONS.

DESCRIBE HOW MOVEMENTS IN THE CONVECTION ZONE CONTRIBUTE TO SOLAR FLARES.

MAGNETIC LINES OF FORCE ARE GENERATED BY MOVEMENT OF CHARGED PARTICLES IN THE CONVECTION ZONE.

DO YOU THINK FUSION REACTIONS IN THE SUN’S CORE WILL CONTINUE FOREVER AND GO ON WITH NO END? EXPLAIN YOUR ANSWER. PBS VIDEO SECRETS OF THE SUN
