What primarily causes ocean tides on Earth?

Earth's rotation, which pushes water outward at the equator The Moon's gravitational pull, which is slightly stronger on the near side of Earth than the far side Wind patterns driven by the Sun's heat Earth's magnetic field interacting with the ocean's salt water

How many high tides does most coastline experience in approximately 24 hours?

One high tide and one low tide About two high tides and two low tides Four high tides and four low tides Tides happen once a week

What are spring tides?

Tides that only occur in the spring season Extra-strong tides that occur when the Sun, Moon, and Earth are aligned — at new and full moon Tides caused by underwater springs and volcanoes Weak tides that happen at the equator

What are neap tides?

Tides that are extra-strong near the equator Tides that happen every 24 hours Weaker tides with a smaller range that occur when the Sun and Moon are at right angles to each other (quarter moon phases) Tides caused by storms at sea

Why does the same side of the Moon always face Earth?

The Moon does not rotate at all The near side of the Moon is heavier, so gravity always pulls it to face Earth The Moon is tidally locked — Earth's gravity has slowed the Moon's rotation so it takes the same time to spin once as it does to orbit Earth The Moon spins once per year, which makes it appear stationary from Earth

How do tides affect Earth's rotation over millions of years?

Tides have no effect on Earth's rotation Tides speed up Earth's rotation Tides gradually slow Earth's rotation — days are getting slightly longer over time Tides cause Earth's axis to tilt more over time

Does the Sun also cause tides on Earth?

No — only the Moon causes tides Yes, and the Sun has a much stronger tidal effect than the Moon because it is so much more massive Yes, but the Sun's tidal effect is about half as strong as the Moon's despite the Sun being much more massive Yes, but only in winter when Earth is closer to the Sun

If you were standing on the Moon, what would Earth look like as it goes through its daily cycle?

Earth would rise and set once per day just like the Sun Earth would appear to hang nearly stationary in the sky and go through phases like the Moon does from Earth You would not be able to see Earth from the Moon Earth would appear tiny — about the size of a bright star

Which body in our solar system has the most extreme tidal forces acting on it?

Earth's oceans, which have the largest tides The Sun, which is pulled by all the planets Io, a moon of Jupiter, which is squeezed and stretched by Jupiter's massive gravity, causing intense volcanic activity Mars, because it has two moons pulling it in different directions
