Earths position
The third planet from the sun
What is Earth
How long it takes plants to travel a complete orbit around the sun
What is a year/orbital period?
–the fusing of smaller, lighter hydrogen atoms to form a larger, heavier helium atom (which releases energy)
What is fusion
What is earths rotation on its axis
the wobble in Earth’s rotational axis
What is precession
Universe began as a point and has been expanding ever since
What is the big bang theory ?
All planets move in a elliptical motion with the sun at one focus
What is keplers first law
splitting of bigger, heavy atoms into smaller, lighter atoms
What is fission
This is the cause of seasons
What is the tilt of the Earth on its axis as it revolves around (orbits) the Sun
a change in the angle of tilt of Earth’s axis
What is nutation
Planets that revolve around the sun
What is the solar system?
A line that connects a planet to the Sun sweeps out equal (=) areas in equal (=) times.
What is Keplers Second law ?
Blocks Ultraviolet radiation from the sun
What is the ozone
The center of mass between a planet and the Sun
What is barycenter
Earth
Solar System (3rd planet from Sun)
Milky Way Galaxy (the Orion Arm)
Local Group (about 40 galaxies)
Supercluster (Virgo)
Universe!
What is the hierarchy of the universe
The square of the orbital period of any planet is proportional to the cube of the semi major axis of its orbit.
What is Keplers third law
transfer of energy through space by EM waves
What is radiation
Earth is turning back towards the sun
What is spring
In about 12,000 years because of this wobbling on the axis. Earths north star will now be facing vega
What is precession
The galaxy our solar system exists in
What is the milky way galaxy
The earth travels around the sun in this motion
What is an ellipse ?
the transfer of energy that occurs when molecules collide
What is conduction
This causes bulging at the equator
What is centrifugal force
This can cause earths tilt to increase or decrease causing a change in seasons
What is nutation
