HELIOCENTRIC AND GEOCENTRIC

   For a long time scientist thought that earth is located in the middle of the solar system by many years thought that the sun revolve around the earth and other celestial bodies and this action is call Geocentric model  one of the scientists who support and believe in this model was Ptolemy II, the Catholic church was also in support of this idea they believe that God create the galaxy perfectly that sun revolve around our satellite  giving us all the things that we need. But after all a scientist come up that the Geocentric is not the perfect model for our planetary system. Than he thought that the globe is not located on the center of the solar system  and, the sun is located in the middle instead. Galileo Galilei was the scientist that he come up with this model that sun is located in the center of the solar system this model is called Heliocentric, one thing that proves this model is the right the because of  Parallax, Parallax means the different stars we see in different location this is called Parallax. This is a great evidence to support that earth goes and moves around the sun.

CRITICAL THINKING QUESTION ?

How do the Earth’s motions affect us each day? 

Every day our planet move on its axis or revolving around the sun, earth rotate on its axis giving us day day and night so our temperature can be measured giving us the enough sunlight for us to live and also to earth to be intact, if earth does not move our planet will be night one side and lighted the other side, if planet does not revolve or rotate half of our planet will be covered by ice and other half would be extremely hot and automatically we die because we can't live in this conditions.

How do the Sun, Moon and Earth interact?

There are celestial bodies that need of each other to be intact as earth needs the moon and needs of the sun also, earth needs the moon to reduce the velocity of the rotation so moon keeps the exact movement that we the human need in one day, earth needs the sun because most of the energy used by the human come from the sun, also we need sunlight because our bodies needs it.
