Explorando la Tierra, el sol y la luna: mareas

The video explains the phenomenon of tides, which are the rise and fall of ocean levels every 12:30 hours, with high and low tides occurring every 6 hours. The gravitational pull of the moon on the Earth's water is responsible for these movements. The video illustrates how the moon's gravity causes high tides at the point closest to the moon and directly opposite it, while low tides form between these points. Additionally, the video discusses how the size of tides can vary depending on the time of year and the Earth's location.

How often do high and low tides occur?

• Every 6 hours

• Every 24 hours

• Every 3 hours

• Every 12 hours

What is primarily responsible for the occurrence of tides?

• The rotation of the earth

• The interaction between the moon and the earth

• The wind

• The sun's heat

What causes the water on Earth's surface to move towards the moon?

• The earth's rotation

• The sun's gravitational force

• The moon's gravitational force

• The earth's magnetic field

Where does low tide form in relation to high tides?

• Between the two high tides

• On the opposite side of the earth

• Directly under the moon

• At the poles

What factors can cause tides to vary in size?

• The time of year and location

• The temperature of the ocean

• The speed of the wind

• The time of day
