Las Mareas

The video explains the phenomenon of tides, highlighting the gravitational pull of the moon and its effects on Earth. It describes how tidal forces cause water to rise and fall twice daily and how these forces also affect the Earth's crust and the moon. The video discusses the impact of gravity over distance and the role of the sun in tidal strength. It predicts future changes in the Earth-Moon system, including potential disintegration if the moon gets too close to Earth. The video concludes with a warning about the destructive power of tidal forces near black holes.

Why do we experience two high tides each day?

• Because the Earth rotates twice a day.

• Due to the gravitational pull of the moon being stronger on the side facing it.

• Because the Earth's crust moves up and down.

• Because the sun's gravity pulls the water twice a day.

What happens when the sun and moon align?

• The tides become weaker.

• The tides become stronger.

• The moon moves closer to the Earth.

• The Earth's rotation speeds up.

How do tidal forces affect the Earth's crust?

• They cause the crust to bulge.

• They make the crust sink.

• They cause the crust to crack.

• They have no effect on the crust.

What could happen if the moon gets too close to Earth?

• The moon would become a new planet.

• The moon would disintegrate.

• The tides would disappear.

• The Earth would stop rotating.

What is a potential effect of flying towards a black hole?

• Your spaceship would be torn apart by tidal forces.

• Your spaceship would become invisible.

• Your spaceship would become a star.

• Your spaceship would speed up.
