Which is a similarity between a neap tide and a spring tide?
Neap tides occur once a year in fall and spring tides once a year in spring.

Why is the timing of tides predictable?
because ocean water density is predictable
because the moon's path is predictable
because the sun's movements are predictable

Once a month, Earth passes directly between the moon and the sun. Is a solar eclipse possible during this time?
Yes, because new moons happen when Earth is between the moon and the sun, and solar eclipses happen only during new moons.
No, because new moons happen when Earth is between the moon and the sun, and solar eclipses happen only during full moons.
Yes, because full moons happen when Earth is between the moon and the sun, and solar eclipses happen only during full moons.
No, because full moons happen when Earth is between the moon and the sun, and solar eclipses happen only during new moons.

Taylor and Jose pulled their boat up onto the beach and went on a hike. When they returned, the beach was covered by water and the boat was floating offshore. What is the most likely explanation?
The spring tide came early.
The gravitational pull of the sun and moon decreased the tidal range.
The low tide receded and pulled the boat out to sea.
The water level rose due to the high tide.
