Las capas de la Tierra

The video explores the Earth's structure, starting from the inner core, a solid sphere of iron and nickel, to the outer core, which is liquid. It then describes the mantle, the thickest layer, and the crust, where we live. The crust is divided into plates that move slowly over the mantle, a process known as plate tectonics.

What is the innermost layer of the Earth made of?

• Gold and silver

• Iron and nickel

• Lead and tin

• Copper and zinc

Which layer of the Earth is in a liquid state?

• Crust

• Inner core

• Mantle

• Outer core

How thick is the Earth's mantle approximately?

• 2000 km

• 1000 km

• 500 km

• 3000 km

What is the Earth's outermost layer called?

• Crust

• Core

• Mantle

• Lithosphere

How much do the Earth's plates typically move each year?
