Earthquakes Both Volcanoes
* Richter scales and Mercalli scale  *can be destructive and cause death *Danger from hot lava, ash, 
to measure poisonous gases
* Destruction and danger is mostly from man made falling objects  * natural disasters *Less common than earthquakes
* Earthquakes happen everyday * Hard to know when they will happen * usually seen- know where, gives signs- smoke, ash, rumble, smell 
* Easier to know where than when- no warning * Found near faults * near convergent or divergent boundaries
* caused by the movement of plates
* after shocks or tremors
* more Earthquakes near transform boundaries or strike slip faults
  Space Reviewing Main Ideas:
  • Earth is spherical and bulges at the equator
  • Earth rotates once per day and orbits sun a little more than 365
  • Earth has a magnetic field
  • Seasons on earth are caused by the tilt of the Earth's axis and it orbits the sun

The Moon

  • Earth's moon goes through phases that depends on the relative positions of the sun, moon and earth
  • Eclipses occur when earth or the moon temp blocks sunlight from reaching the other
  • Moon's Maria are the result of ancient lava flows. Craters on the moon's surface formed impacts with meteorties, asteriods, comets
Exploring Earth's Moon
  • Clementine spacecraft took detailed photographs of the Moon's surface and collected data indicating the presence of water deep in craters
  • NASA's lunar Prospector Spacecraft found additionial evidence of ice.
                                     Visual Main Idea:
Mars sized object collides with Earth ----------causes
Part of Earth's crust and mantle to be vaporized and ejected----- which leads to
Ejected debris orbiting Earth, forming a ring of hot dust and gas----- which forms
The Moon when particles in the ring join together.
Impact Basin: impact crater- the depressionleft behind by an object striking the moon
Sphere- round 3 dimensional object its surface is the same distance from its center
axis- imaginary vertical line around where Earth spins
rotation- causes night and day spinning of the Earth on its axis
revolution- Earth's yearly orbit around the sun
ellipse- elongated closed curve
solsitice- day when the sun reaches its greatest distance North or South of the equator
equinox- occurs when the sun is directly above the Earth's equator
Moon Phase- different forms that the moon takes in its appearance
New Moon- when the moon is between Earth and the sun
Waxing- more of the illuminated half of the moon can be seen each night
full moon- occurs when all of the moon's surface facing earth reflects light
waning- less of its illuminated half each night
solar eclipse- occurs when the moon moves directly between the sun and Earth and casts a shadow over part of Earth
Lunar Eclipse- Shadow falls on the moon
Maria- dark, flat regions
