A[n] ___________ tide occurs when the sun, Earth, and the moon are inline.
spring
high
low
neap
What is a high tide?
Sea pulled TOWARD the moon where Earth is CLOSEST to the moon
Sea pulled AWAY from the moon where Earth is FARTHEST to the moon
Sea pulled AWAY from the moon where Earth is CLOSEST to the moon
You visited the beach at 12 pm (lunchtime) and it is low tide. If you return 6 hours later, what tide will you see?
high
low
none
spring
_______are daily changes in ocean water.
Waters
Tides
Colors
Earths
Which type of tide is represented in the picture?
Neap because the sun and moon are working opposite each other.
Neap because of the tidal bulges.
Spring because the sun and moon are lined up and working together.
Spring because that is where the Earth is its orbit.
What moon phases occur with neap tides?
New and full moon
First and new moon
Third and full moon
First and third quarter
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. What does the force of gravity depend on?
mass and weight
weight and speed
mass and distance
speed and distance
The rotation is responsible for what we call _________; the tilt on the axis influences the ________.
a day; a year
a day; seasons
a year; seasons
a day; the phases of the moon
Both the Moon and the Sun influence the tides on Earth. The moon has a much greater influence though. Why is that?
because the Sun is much less dense
because the Sun is gaseous, not solid
because the Sun is so far away from Earth
because the Sun is less massive than the Moon
As the planets have larger orbits, what happens to their orbital speed around the sun?
The larger planets further from the sun have greater orbital speeds.
The orbital speeds remain the same regardless of distance from the sun.
The orbital speeds of the planets decreases as they get further from the sun.
The orbital speed depends on numerous factors not just distance from the sun.
If Earth were not tilted on its axis, what change would we experience?
Day length would be less than 24 hours.
Both sides of the moon would be visible.
Temperatures would be constant year round.
The length of the year would be more than 365 days.
Large tides, called spring tides, are experienced in the Earth's oceans when the moon is in position

The temperature around Earth's equator stays about the same throughout the year. Why does this happen?
The temperature around Earth's equator stays about the same throughout the year. Why does this happen?
The equator receives less direct sunlight during the year.
The equator receives about the same amount of sunlight all year long.
The equator receives about the same amount of sunlight all year long.
