Warm-up (9-8-14)
• Determine the independent and dependent variables, as well as the control group, experimental group, and the constants in the following scenario.– Tim just started a new landscaping company. He decides to test how
well his lawn mower works to see if he needs a new one. He rents three high powered mowers from the store and tests them along with his current mower on the same size lawns.
• Earth Systems:– What do you find most interesting about the solar system?– Do you think that various phenomena in space impact or affect us here
on Earth? Why / Why Not?

General Notes on the Planets
• Solar system is made of 8 planets and other objects that orbit the Sun
• The orbits are elliptical, so a planet’s distance from the Sun will vary.
• Movement of a planet around the Sun is the revolution
• The spin of a planet on its axis is its rotation
![Page 20: Earth Systems. Warm-up (9-8-14) Determine the independent and dependent variables, as well as the control group, experimental group, and the constants.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649db95503460f94aa8f3d/html5/thumbnails/20.jpg)
General Notes on Planets
• Venus and Uranus display retrograde motion, meaning they rotate clockwise instead of counter clockwise
• Uranus is tilted on its side with its axis nearly parallel to the plane of its orbit.
• Four planets closest to the sun are the inner planets (Mercury, Venus, Earth, Mars)
• There is an asteroid belt in between the orbits of Mars and Jupiter
• The planets beyond the asteroid belt are the outer planets

Mars
• 687 days to orbit the sun• Diameter is half of Earth’s• Gravity is 2/5 that of Earth’s • Weak magnetic field• Similar axis tilt to Earth
– 4 seasons similar to Earth• Year is twice as long as Earth year (what does this do to
the seasons?)• Thin atmosphere
– 95% Carbon dioxide and 5% nitrogen and argon

Mars
• Thin atmosphere, so pressure is less than 1% that of Earth
• Polar ice caps – most likely water ice covered by frozen CO2
• Temperature difference between poles and soil = strong winds and swirling dust storms
• Largest volcano = Olympus Mons– Not related to plate motions
• Valles Marineris – canyon system as long as US• What happened to the water that once covered the
surface of Mars?

Jupiter
• Takes 11.9 years to orbit the sun• Rotates faster than any other planet (about 10 hours)• Largest planet – more than twice total mass of all other
planets combined• Strongest magnetic field• Interaction between solar wind and magnetic field causes
auroras• Jupiter radiates 2x as much heat into space compared to
what it receives– May come from original heat of formation and from contraction
due to gravity

Jupiter
• Great Red Spot– One of several spots– Photos indicate spots might be calm areas rotating
slowly in violent atmosphere• No thick, dense clouds• High temperatures and pressures in upper
atmosphere• Deep atmosphere is convective• What does this mean?
![Page 104: Earth Systems. Warm-up (9-8-14) Determine the independent and dependent variables, as well as the control group, experimental group, and the constants.](https://reader035.fdocuments.us/reader035/viewer/2022062421/56649db95503460f94aa8f3d/html5/thumbnails/104.jpg)
Saturn
• 30 Earth years to complete one orbit• Turns on its axis about every 10 hours• Colored zones and belts – areas of rising and sinking gas• Fewer belts than Jupiter• Lowest density – it could float!• Has source of internal heat – radiates out more heat
than it receives• Weaker magnetic field than Jupiter but stronger than
Earth• Rings are made of ice with some rock – remains of
asteroids, comets, small moons crushed by gravity

Uranus
• 84 years to complete one orbit• Average surface temp. is -200 degrees C• Turns on axis once every 17.2 hours• Axis of rotation is parallel to orbital plane
– It is tipped on its side!– Why did this happen?
• Magnetic field is present but is not tipped on its side– Difference is 60 degrees– Difference causes magnetic field to trace spiral pattern in
solar wind as planet rotates• Turquoise color due to methane gas

Neptune
• Rotates on axis 16.1 hours and takes 165 years to orbit sun
• Magnetic axis is tipped 47 degrees compared to axis of rotation– Also offset from the planet’s center– Scientists think motions of conductive material (maybe
water) generate the magnetic field• Harsh winds 2000 km/hr• Atmosphere is mostly hydrogen, some helium, and
small amount of methane

Stars
• Constellations: groups of stars– Typically named after mythology– 88 visible constellations– Not natural groupings– Varying distances from Earth– Apparent regular movement across our sky is
caused by Earth’s motions• Rotation and revolution
– Position changes with the seasons

Apparent Magnitude
• Measure of how bright a star appears to be to an observer on Earth
• Lower the magnitude number, the brighter the star is
• Faintest stars that are visible are sixth-magnitude stars
• Each magnitude differs from the next by a factor of 2.5– First magnitude star is about 2.5 times brighter than a
second magnitude star

Distance
• Astronomical Unit (AU) – average distance between the Earth and the sun– 150 million kilometers
• Nearest star to Earth is Proxima Centauri but is still more than 2.5 kilometers away if the Earth and Sun were dots 1 cm apart
• Light Year – distance that a ray of light travels in one year– 9.5 trillion kilometers
• Proxima Centauri is about 4.2 light years away from Earth
• Parallax – change in object’s direction due to a change in observer’s position– at different times of the year a nearby star doesn’t seem to be in
exactly the same position against the backdrop of stars
