Una Tierra gemela

The transcript describes how Earth's twin, Theia, collided with Earth, leading to significant changes. The collision increased Earth's size and gravity, allowing it to retain an atmosphere and develop a magnetic field, which protects against solar winds. The debris from Theia formed the Moon, stabilizing Earth's orbit and creating tides. These events were crucial for Earth's ability to support life.

What was the primary consequence of the collision between Earth and Theia?

• Theia became a new planet.

• Earth's orbit became unstable.

• Earth's size and gravitational pull increased.

• Earth's atmosphere was lost.

How does Earth's magnetic field protect the planet?

• By creating a stronger gravitational pull.

• By stabilizing Earth's orbit.

• By increasing the planet's temperature.

• By deflecting solar winds towards the poles.

What natural phenomenon is caused by particles hitting Earth's atmosphere?

• Earthquakes

• Volcanic eruptions

• Auroras

• Tornadoes

What role does the Moon play in Earth's stability?

• It increases Earth's gravitational pull.

• It stabilizes Earth's orbit and creates seasons.

• It causes earthquakes.

• It absorbs solar radiation.

How do the tides benefit Earth's ecosystems?

• They prevent volcanic eruptions.

• They create habitats for various species.

• They help regulate Earth's temperature.

• They provide a source of fresh water.
