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 only happen 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.

because winds are predictable
because the moon's path is predictable

underwater earthquakes, volcanic eruptions, or landslides
the gravitational pull of the moon on the water at Earth's surface

A
B
Which shows a lunar eclipse?
A
B
Which statement is true?
Water moves around the globe, moving the sea level up and down in different places.
Earth rotates around inside the water, in and out of the tides.
The moon's pull on the tides is the same as the sun's pull on the tides.
The moon's pull alone determines the tides because the sun's pull never changes.
The moon's pull on the Earth's tides is always constant. So is the sun's. It's only their relationship that creates the change in tides.
