Núcleo (geología)

The video explains the core as the central, often hotter and denser part of structures like stars, planets, and galaxies. It focuses on Earth's core, highlighting the inner core's high temperature and pressure, which keeps iron solid. In contrast, the external core has lower pressure, allowing iron to be liquid.

What is typically found at the center of large structures like stars and planets?

• A liquid surface

• A central, hotter, and denser core

• A colder and less dense region

• A gaseous outer layer

What is the approximate temperature of the Earth's inner core?

• 5000 °C

• 6200 °C

• 7000 °C

• 8000 °C

Why does the Earth's inner core remain solid despite its high temperature?

• Because of the high pressure

• Due to the low pressure

• Due to the presence of water

• Because it is made of ice

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

• Gold

• Copper

• Iron

• Nickel

What happens to iron in the Earth's outer core?

• It turns into a liquid

• It evaporates

• It remains solid

• It becomes gaseous
