Cards (50)

  • The sun's temperature is 15 million degrees celsius
  • The sun is in it's main sequence estimated at 4.5 billion years old
  • The sun is mostly composed of Hydrogen and Helium
  • The photosphere is the glowing layer of gasses on the sun's surface
  • The chromosphere is found above the photosphere
  • the core is the inermost layer of the sun
  • the passage way for all energy being released from the core is called the radiative zone
  • Sunspots are the dark spots that are found on the sun's surface
  • Solar Prominences look like loops on the sun's surface
  • the sun's diameter is 1,400,00 km
  • the earth is 4x the moon
  • The moon rotates as the same rate as the earth
  • it takes the moon 27 earth days to complete one orbit around the earth
  • the moon's surface is a rocky surface due to impact of astroids, meteorites, and comets
  • Lunar Regolith is the gray powdery dust found on the moon's surface
  • Highlands are the light areas of the moon
  • Maria are the dark spots on the moon
  • Crust is the outermost layer of the moon
  • Mantle is divided into 2: Rigid Litosphere and Athenosphere
  • Core is the iinnermost layer of the moon and is surrounded by liquid iron
  • Troposphere is the lowest layer of the atmosphere, 10-50km above the Earth's surface
  • Stratosphere is the second layer which contains the ozone layer
  • The Mesosphere is the third layer, it is the coldest layer which causes meteors to burn here
  • The thermosphere holds the ionsphere
  • The Exosphere is thee outermost layer and contains hydrogen and helium gasses
  • The atmosphere is important because it filters solar radiations
  • The Earth is approx. 4.5 billion years old
  • The solid outer core of Earth is made of iron and nickel.
  • The Earth's inner core is a solid ball of iron
  • Glutenburg discontinuity is between the mantle and crust
  • The Mohorovic discontinuity is between mantle and core
  • the crust is the outermost layer and is 1% of the earth's mass
  • Continental crust can be described as old and thick
  • Oceanic crust can be described as young and dense
  • The rotation of the earth takes 24 hours to complete
  • The movement around the sun and takes 1 year to complete is called a revolution.
  • Equinox refers to a day with the equal day and night
  • the Tropic of Capricorn can be found at 23 1/2 S
  • The Tropic of cancer can be found at 23 1/2 N
  • The Artic circle can be found at 66 1/2 N
