¿Qué temperatura tiene el núcleo de la Tierra?

The video explains the structure and significance of Earth's core, composed of iron and nickel, and its role in generating the planet's electromagnetic field. It describes a laboratory method to simulate core conditions using a hydrogen gas cannon to recreate high pressure and temperature. The experiment measures the temperature at which iron melts during a high-speed collision, providing insights into the core's conditions. The findings suggest that the core is a significant heat source, hotter than the surface of the Sun.

What is the primary composition of the Earth's core?

• Silver and gold

• Copper and zinc

• Aluminum and magnesium

• Iron and nickel

How do scientists simulate the conditions of the Earth's core in a laboratory?

• By heating water to extreme temperatures

• By freezing metals to low temperatures

• By using a vacuum chamber

• By using a large cannon to create high pressure

What is the initial pressure in the hydrogen-filled tube used in the experiment?

• 10 times atmospheric pressure

• 1000 times atmospheric pressure

• 100 times atmospheric pressure

• 200 times atmospheric pressure

What speed does the projectile reach in the experiment?

• 8 km per second

• 5 km per second

• 10 km per second

• 12 km per second

What does the color of the light emitted during the experiment indicate?

• The pressure inside the cannon

• The speed of the projectile

• The density of the iron

• The temperature at which iron melts
