6 Science - Planets Flashcards
The line on which an object rotates
Rotation axis
Is a day when earths rotation axis is the leaning along earth’s orbit
Equinox
Is a day when earth’s rotation axis is the most forward or away from the sun
Solstice
A spinning motion
Rotation
The motion of one object around the other
Revolution
Bright streaks of light around the craters
Rays
The impact of many objects
Highlands
When objects from space crashed into the moon
Craters
Large dark flat areas
Maria
When the entire moon moves through earths umbra
Solar eclipse
When the entire moon moves through earths umbra
Total lunar eclipse
The lighter part of a shadow where light is blocked
Penumbra
The central,darker part of a shadow where light is blocked
Umbra
When only part of the moon passes through earths umbra
Partial lunar eclipse
Occur at the tidal bulges
High tides
Occur between high tides
Low tides
The daily rise and fall of sea level
Tides
Weaker on one side, strong on the other
Tidal bulges
When large objects hit the earth it formed
Moon
Giant ball of hot gas
The sun
When the suns and moons gravitational effects combine
Spring tides
When the sun,earth,and the moon form a right angle
Neap tides
New moon,first quarter,full moon, last quarter
4 lunar cycle phases
When sunlight illuminates only the Moon’s near side – the side that always faces Earth – we call that a full moon. The rest of the month, we see a different amount of the daytime side of the Moon each day
How the 4 lunar cycle phase works
The earth’s spin axis is tilted with respect to its orbital plane.
Earths tilt and seasons
keeps Earth in orbit around it
Sun’s gravity and the earth
