  1. Explain the origin of the Earth’s motion based on the origin of the galaxy as its solar system?  Im going to go off the big bang theroy to explain earths orbit. There is a theroy that a nebula collided the gas dust particles together 

chapter 1.   Earths motion through space

  1. Explain planetary orbits, especially that of the Earth, using Kepler’s Laws.

Explain relative motion of the Earth in the solar system, the solar system in the galaxy, and the galaxy in the universe?  Kepler's laws states that the the sun acts as a foci for the planets to close in on but they never get there so they keep moving in a circular motion



  1. Explain relative motion of the Earth in the solar system, the solar system in the galaxy, and the galaxy in the universe?   the earth moves around the sun which is in the center of our galaxy and the galaxies have no specific directions, thats why the collide sometimes.

Explain precession?  the movement of something on its axis ex. earth and how it spins on its axis

barycenter.  the center of a mass of two or more bodies floating around each other 

nutation. inclantion on the axis of a object

EEn.1.1.2 Explain how the Earth's rotation and revolution about the Sun affect its shape and is related to seasons and tides.

Chapter 2 

  1. Describe daily changes due to rotation, seasonal changes due to the tilt and revolution of the Earth, and tidal impact due to the gravitational interaction between the Earth and moon.     time happens due to the rotation because as it rotates the sun wont it certain parts of the earth making it soft.           seasonal changes happens when the sun is further away causing winter or closer causing summer.          the moon changes the tides by interacting with the gravity of the water causing waves to sprout 
  1. Develop a cause and effect model for the shape of the Earth explaining why the circumference around the equator is larger than that around the poles. 

cause- the planet isnt a perfect sphere and it buldges around the equater and the poles dont get as much heat 


effect- the heat cause the equater to stretch more and the polar dont so they stay the same

      Chapter 3

  1. Compare combustion and nuclear reactions (fission and fusion).  Explain why fusion produces radiant energy of stars.
  2. fusion takes a high amount of energy and a dense amount of gravity and thats what stars need
  3.  fission splits into parts so it cant ever build up into anything
  1. Summarize how energy flows from the sun to the Earth through space. 
  2.  energy flows to earth through radiation and as it reaches plantets it heats them up up as it reaches them 
  1. Identify forms of energy (electromagnetic waves) produced by the sun and how some are filtered by the atmosphere (X-rays, cosmic rays, etc.)
  2. ultravilot radiation and the ozone filters them out the harmful chemicals and lets in the non harmfull ones

       Chapter 4

  1. Explain how solar energy is transformed into chemical energy through photosynthesis.
  2. plants get energy from sun and transform it into glucose which is what they eat
  1. Explain differential heating of the Earth’s surface (water temperature vs. land temperature). 
  2. there isnt much difference but land temperature is affected by where the sun hits, water is where the the heat spreads to different parts of the ocean 
  1. Explain how the tilt of the Earth’s axis results in seasons due to the amount of solar energy impacting the Earth’s surface.
  2. solar energy is heat and the amount of heat hitting the earth causes the seasons 

  1. Explain how the Earth’s magnetic field protects the planet from the harmful effects of radiation. 
  2. earth magnetc field keeps out dangoures space particles and if the do get in its at the poles so no plants get harmed

orbit- curved path of a celestial body around another


Rotation- spinning ex) earth on it's axis


revolution- how long it takes the earth to get around the sun


keplers law of motion- all planets move around the sun


Precession- slow movement of the earth on its axis


tilt- the earth has a slight tilt 


pole- the projection of earths axis


nutation- periodic inclanation of an object on its axis

Barycenter- mass of two or more objects floating around each other


neap tide- moon causing no difference between high and low tide


star- hot ball of gas in our universe


planet- astronomical body floating around a stat

electromagnetic waves- waves that can travel through space


axis- fake line in which something rotates


spring tide- tide just after a full moon

satellite- object that follows a planets pull


fission- two things coming together


fusion- two things coming apart


radiant energy- energy that comes of the sun and gives us heat
