Waxing crescent
How can you tell if the moon is waxing?
The light is on the right
The light is on the left
The sun is behind the moon
When the light is moving
When the Moon passes directly between the Sun and the Earth it causes what phenomena?
A lunar eclipse
A new moon
A solar eclipse
A full moon
When there are extreme high tides and low tides it is called a _________ __________
High tide
Spring tide
Full moon tide
Neap tide
What kind of tide is happening?
Low tide
Spring tide
Neap tide
Weak tide
Neap tides occur during which moon phase?
Full moon
Crescent moon
Quarter moon
New moon
How does increasing distance effect the gravity between two objects?
it increases the gravitational pull
It prolongs the gravitational pull
It destroys all gravitational pull
It decreases the gravitational pull
Objects with more mass have a ______________ gravitational pull.
Weaker
Equal
Stronger
Normal
What kind of tide is shown in the picture?
Spring tide
Full moon tide
High tide
Neap tide
Spring tides happen during which moon phases?
The quarter moon
The crescent moons
The full moon and new moon
The gibbous moons
When the high tide is not so high and the low tide is not so low it is called a _____________ tide.
Spring
Neap
Chill
Moderate
Why does the moon have a stronger gravitational pull on Earth than Mars?
The moon is bigger than mars
The moon is more important than mars
The moon much closer than mars
The moon is heavier than mars
Which picture is showing a lunar eclipse?
Top picture
Bottom picture
Neither
Define and explain how the celestial phenomena in the picture occurs?
Solar eclipse, when the sun is blocked by the moon
Partial eclipse, when the sun is partly blocked from the Earth
Lunar eclipse, when the Earth blocks the sun from the moon
Linear eclipse, when the Earth, sun, and moon align
Why are the tides more extreme (spring tides) during the full moon and the new moon?
Because the suns gravitational pull is stronger than the moon
Because the gravitational pull of moon and sun are combined
Because the Earth is spinning on a tilted axis, tipping the oceans that direction
Because the moon is closest to the Earth at that time
What causes the oceans tides?
The gravitational pull of the sun and the moon
Earths gravity
The Earths rotation
Moon phases
During a Neap tide, high tides and low tides are much less extreme, why?
The moon is only half full at that time
There is a lunar eclipse happening
The suns gravity pulls in the opposite direction of the moons gravity, and reduces the overall gravity on Earths oceans
The gravitational pull of mars is counteracting the gravitational pull of the moon.
Which wave has more energy?
The top one
The bottom one
They are equal
Once static electricity is generated through friction, why does the balloon stick to the cats fur?
Because the electrons are flowing from the cat to the balloon
Friction put electrons from the cat onto the balloon, the (+) charged cat fur is attracted to the (-) balloon
Both the cat the balloon are (-) and like charges are attracted to each other
The cat is really dirty and sticky so the balloon is caught on its fur
