  • What are the 4 days each year when the direction of the Earth’s rotation axis is special relative to the Sun called?
    March Equinox, June Solstice, September Equinox, December Solstice
  • autumn begins in Northern Hemisphere; spring begins in Southern Hemisphere
    September Equinox
  • days in the northern hemisphere are shortest and nights are longest- winter begins
    December Solstice
  • the lighter part of a shadow where light is partially blocked
    penumbra
  • Equinox or Solstice- about 12 hours of daylight and 12 hours of darkness everywhere on Earth
    Equinox
  • the large, dark, flat areas on the Moon
    Maria
  • What is the sequence of Moon phases called? And How long does it take for each sequence?
    lunar cycle; one cycle takes 29.5 days or slightly more than 4 weeks to complete.
  • How do the Moon and the Sun affect Earth’s oceans?
    The positions of the Moon and the Sun in relation to Earth cause gravitational differences that produce tides
  • an occurrence during which the Moon moves into Earth's shadow
    Lunar Eclipse
  • Solar or Lunar? only can occur during a New Moon, when Earth and the Sun are on opposite sides of the Moon
    Solar Eclipse
  • spring begins in Northern Hemisphere and autumn begins in Southern Hemisphere
    March Equinox
  • the line on which an object rotates
    rotation axis
  • Why does Earth orbit the Sun?
    The pull of the Sun’s gravity keeps Earth revolving around the Sun in a nearly circular orbit
  • How many days does it take for the Moon to make one full revolution around the Earth?
    27.3
  • How many days it takes the Earth to make one complete revolution around the Sun?
    365.24 days
  • days in the northern hemisphere are longest and nights are shortest- summer begins
    June Solstice
  • Light from the Sun and other wide sources casts shadows with two distinct parts. What are they?
    Umbra and Penumbra
  • the portion of the Moon or a planet reflecting light as seen from Earth
    phase
  • Solar or Lunar? can only occur during the Full Moon phase
    Lunar Eclipse
  • occur when the Sun and the Moon form a right angle with Earth; high tides are lower and low tides are higher
    Neap Tides
  • How many days does it take for the Moon to make one full rotation?
    27.3
  • an occurrence during which the Moon's shadow appears on Earth's surface
    solar eclipse
  • phases of the Moon during which less of the Moon's near side is lit each night
    Waning Phases
  • the spin of an object around its axis
    rotation
  • phases of the Moon during which more of the Moon's near side is lit each night
    Waxing Phases
  • What direction does the Earth rotate?
    counterclockwise- west to east
  • What causes the seasons?
    Earth's tilted axis
  • What are the 8 different Moon phases?
    New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent
  • Why is Earth warmer at the equator and colder at the poles?
    Energy from the Sun becomes more spread out as you move away from the equator;Regions near the poles receive less energy than regions near the equator
  • Solar or Lunar? Earth is in a line between the Sun and the Moon
    Lunar Eclispe
  • the orbit of one object around another object
    revolution
  • when Earth's rotation axis is tilted neither toward nor away from the Sun
    Equinox
  • occur when the Sun, Earth, and the Moon are in a line; higher high tides and lower low tides
    Spring Tides
  • the path an object follows as it moves around another object
    orbit
  • the periodic rise and fall of the ocean's surface caused by the gravitational force between Earth and the Moon, and between Earth and the Sun
    Tide
  • How long does it take the Earth to make a full rotation?
    about 24 hours- helps produce Earth’s cycle of day and night
  • Solar or Lunar? occurs only when the Moon moves directly between Earth and the Sun.
    Solar Eclipse
  • the central, darker part of a shadow where light is totally blocked
    umbra
  • when Earth's rotation axis is tilted directly toward or away from the Sun
    Solstice
