Science test- STARS

Question 1

Fusion

Answer 1

When 2 smaller atoms are forced together to become on larger atom.

Question 2

Difference between alive and dead stars

Answer 2

Alive stars are still fusing. Dead stars are not

Question 3

Nebula

Answer 3

A cloud of space dust mostly hydrogen and helium

Question 4

Small mass main sequence star

Answer 4

Fishing hydrogen into helium. 90% of its life

Question 5

Red giant

Answer 5

Fusing helium into carbon

Question 6

White dwarf

Answer 6

Left over core of a dead star

Question 7

High mass sequence star

Answer 7

Fusing helium. 90% of its shorter life

Question 8

Red super giant

Answer 8

Fuses heavier and heavier element up till iron

Question 9

Super nova

Answer 9

Huge explosion caused by fusing iron in the core robbing it out of energy and it collapses and explodes making all elements heavier than iron

Question 10

Neutron Star

Answer 10

Super massive ball of just neutrons

Question 11

Black hole

Answer 11

A super dense area with extreme gravity

Question 12

The 2 forces balanced in a star

Answer 12

Gravity pulling and fusion pushing out

Question 13

What element are most stars made out of

Answer 13

Hydrogen

Question 14

How do star get their energy

Answer 14

By fusing hydrogen and helium

Question 15

What does a star form

Answer 15

Nebula(a collection of elements or gas some times called dust)

Question 16

Why don’t large stars last as long as small stars

Answer 16

They fuse the elements they have much faster than small stars due to the increased gravity and increased pushing against the gravity

Question 17

Where are heavy atoms made

Answer 17

Atoms heavier than iron can only be made in super nova. This they are all made in super nova

Question 18

What is left behind after a super nova

Answer 18

Depending on the mass of the original star either a neutron star or a black hole

Question 19

What elements do low mass stars produce

Answer 19

Turns hydrogen into helium up to carbon nitrogen and oxygen

Question 20

What elements do high mass stars produce during their life

Answer 20

Heavier elements up to iron so carbon, nitrogen, oxygen, silicon, and all in between up until iron

Question 21

What event causes high mass stars to produce more types of elements

Answer 21

When a star fuses iron it will explode with a super nova and produce all elements heavier than iron. It will also send its material out into other nebula

Question 22

How are we made out of stars

Answer 22

All elements heavier than helium are made inside stars. We are made out of those types of atoms therefore we are made out of star stuff

Question 23

Mr Meyers favorite fact

Answer 23

Supernova spread out those heavier elements they “seed” with other nebula with heavier elem which then form new stars and planets
