how do earth, moon, and sun interact to create tides? Flashcards
what is gravity?
graivty is the attraction between objects, all objects produces gravity
what is mass?
mass is the amount of matter in an object
what is weight?
weight is how much gravity is pulling on the object
how do you measure mass?
balance
how do you measure weight?
scale
what causes moon phases?
the moon orbits the earth, and the earth orbits the sun, the sun shines on the moon, creating moon phases
the angle created by the earth, sun, and moon during new and full moon:
180°
the angle created by the earth, sun, and moon during 1st and 3rd quarter:
90°
how does the sun and moon create tides?
by their gravitional pull to earth’s ocean
how many tides per day?
2 per day
the total time it takes for moon to orbit earth:
24 hrs 50min
spring tides:
new moon or full moon, earth, sun and moon is at a 180º angle
neap tides:
1st quarter or 3rd quarter, earth, sun and moon is at 90º angle
how often does spring and neap tides occur per month?
usally 2 neap tides and 2 spring tides per month
why is during spring tides, the tides are higher than average
the earth, sun, and moon are in a 180º angle, the sun ehances the moon’s gravitational pull on earth’s ocean
