Week 5

Page 2: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

lunar cycle

the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

Page 3: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

crater

a bowl-shaped structure at the top of a volcano or on a planet or moon

Page 4: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

gravity

the force that pulls objects toward each other

Page 5: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

tilt

to lean, tip, or slant to one side

Page 6: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

axis

an imaginary line that passes from the North Pole to the South Pole through

Earth’s center

full moon

the phase of the moon when the side turned toward the earth is entirely lit

Page 8: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

half moon

the phase of the moon when one half of the face turned toward the Earth is lit- can be either side depending on whether it is waxing or waning

Page 9: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

quarter moon

the phase of the moon when one quarter (one- fourth) of the face turned toward the

Earth is lit

Page 10: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

new moon

the phase of the moon when the side turned toward the earth is entirely dark

Page 11: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

rotation

the spinning of a planet or moon on its axis

Page 12: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

revolution

one complete trip of a planet around the sun

Page 13: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

orbit

the path that one object in space takes around another object in space

Page 14: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

waxing

The moon at any time after new moon and before full moon, so called because its

illuminated area is increasing

Page 15: Week 5. lunar cycle the 28 day period in which the moon’s orbit around the Earth causes it to reflect the sun in different phases

waning

The moon at any time after full moon and before new moon, so called because its illuminated area

is decreasing.
