Earth Sun Planets Solar System [appearing pictures with notes] [2]

• The Earth revolves [orbits] around the Sun.
  • 
• We know this because we see different constellations throughout the year.
  • 
• A constellation is a group of stars in a particular shape that has been given a name.
  • 
• The Earth's orbit is not a circle more of an oval.
  • 
• The Sun is not at its centre but more to one side.
  • 
• During its orbit around the Sun the Earth is sometimes closer to the Sun than at others.
  • 
• As the Earth moves closer to the Sun it speeds up [due to gravity].
  • 
• Gravity is a force of attraction.
  • 
• Mass matters, the more massive an object is, the stronger its gravity.
  • 
• As the Earth moves away from the Sun it slows down.
  • 
• Gravity gets weaker the farther you move away from an object.
  • 
• The Earth itself rotates in a circular motion at about 15 degrees per hour.
  • 
• We know this by Star Trails when photographing the night sky with a time lapse camera.
  • 
• Stars leave streak marks where they were at each time a picture was taken.
  • 
• The Earth rotates on its axis [an imaginary line running north-south through the planet].
  • 
• The Earth rotates west to east on an angle of 23 degrees from the upright.
  • 
• All of the other planets rotate at different angles as you can see from this picture.
  • 
• Wind is effected by this rotation.
  • 
• In the northern hemisphere, they rotate anticlockwise and are called hurricanes.
  • 
• In the southern hemisphere, they rotate clockwise and are called tropical cyclones.
  • 
• Let's recap what we have covered............
  The Earth revolves [orbits] the Sun. We know this because we see different constellations throughout the year. A constellation is a group of stars in a particular shape that has been given a name. The Earth's orbit is not a circle more of an oval. The Sun is not at its centre but more to one side. During its orbit around the Sun the Earth is sometimes closer to the Sun than at others. As the Earth moves closer to the Sun it speeds up [due to gravity]. Gravity is a force of attraction. Mass matters, the more massive an object is, the stronger its gravity. As the Earth moves away from the Sun it slows down. Gravity gets weaker the farther you move away from an object. The Earth itself rotates in a circular motion at about 15 degrees per hour. We know this by Star Trails when photographing the night sky with a time lapse camera. Stars leave streak marks where they were at each time a picture was taken. The Earth rotates on its axis [an imaginary line running north-south through the planet]. The Earth rotates west to east on an angle of 23 degrees from the upright. All of the other planets rotate at different angles. Wind is effected by this rotation. In the northern hemisphere, they rotate anticlockwise and are called hurricanes. In the southern hemisphere, they rotate clockwise and are called tropical cyclones.
