Question 5

how the moon was created

Answer 5

collision of a small planet with early earth making a small section break off and form the moon

Question 6

How are tides caused

Answer 6

Tides are caused due to the gravitational pull of the moon

Question 7

What does gravity do?

Answer 7

Pulls objects together and keeps us pulled towards the surface of the earth

Question 8

Answer 8

Earth moves between the sun and moon and blocks the light from the moon

Question 13

what is a nebula

Answer 13

large cloud of dust and gas mostly made of hydrogen

Question 14

Nuclear fusion

Answer 14

occurs when smaller nuclei fuse together to form larger nuclei

Question 15

how is energy in stars transferred?

Answer 15

radiation and convection

Question 15

how does nuclear fusion happen

Answer 15

gravitational forces pull cloud of dust and gas together as particles get closer they gain speed (kinetic energy) and collide with one another more frequently which increases temperature and pressure.

Question 16

stellar life cycle (low mass)

Answer 16

nebula (cloud of dust + gas) —> Prostar (almost a star very hot ) ——> main sequence (fusion millions of degrees Celsius) —–> red giant ——> white dwarf —–> nebula

Question 17

stellar cycle

Answer 17

nebula (cloud of dust + gas) —> Prostar (almost a star very hot ) ——> main sequence (fusion millions of degrees Celsius)——–> supernova (explode)

Question 18

high mass after super nova

Answer 18

Neutron star——> nebula

Question 19

very high mass after super nova

Answer 19

Blackhole
