STAR LEVEL 3

What will happen if the temperature and pressure in the core of the Sun become too high?

• it formed a globe

• nuclear reaction will take place

• star is formed

• an explosion will occur

what will happen when a lot of heat is generated heat up the outermost layer of star?

• hydrogen within this layer starts to burn

• release hydrogen

• a star is formed

Particles in plasma such as electrons, protons and alpha particles the erupt from the Sun to outer space travel together at high speeds known as

• solar wind

• coronal mass ejestion

• solar flares

• The gases and dust particles in a nebula are pulled by a strong gravitational force which causes it to..

• form a globe

• form a helium gas

• form a dust and gases

In a star, a lot of heat is generated which will heat up the outermost layer of star. As a result,

• hydrogen within this layer starts to burn

• hydrogen released

• helium released

• ''Particles in plasma such as electrons, protons and alpha particles the erupt from the Sun to outer space travel together at high speeds known as solar wind.''

• This refer to:

• solar wind

• black hole

• neutron star

• white dwarf

star that is formed is known as a

• protostar

• massive star

• neutron

• - - - - - - - - - that are very strong can throw out matter from the Sun into space at speeds ranging from 600 km s^-1 to more than 1000 km s^-1

• prominence

• solar flares

• coronal mass ejection

The speed of ------------ is supersonic with values ranging from 250 km s^-1 to 750 km s^-1.

• solar wind

• prominence

• protostar

• The granules are the upper part of the convection zone of the plasma which is extremely hot with a with temperature as high as...

• 5800 Celsius

• 300 Celcius

• 4500 Celcius

• 9800 Celcius
