¿CREES que SABES algo de CIENCIA?

The video explores various scientific questions, including why the sky is blue, the nature of black holes, gravitational waves, the life cycle of stars, why the sun shines, plate tectonics, dark matter, and quarks. It aims to understand what people know about these topics, encouraging open discussion and exploration of scientific concepts.

What is one reason the sky appears blue?

• Reflection of the ocean

• Scattering of sunlight by the atmosphere

• Absorption of red light

• Presence of blue gases

What is a black hole?

• A large planet with strong gravity

• A void in space with no matter

• A dense mass that attracts everything, including light

• A star that has exploded

What are gravitational waves?

• Waves caused by the movement of tectonic plates

• Ripples in space-time caused by massive objects

• Waves emitted by the rotation of the Earth

• Waves of light from distant stars

What happens when a star runs out of energy?

• It becomes a black hole

• It turns into a planet

• It goes supernova and may become cosmic dust

• It simply disappears

Why does the sun shine?

• It absorbs energy from nearby planets

• It is made of glowing gases

• Because it reflects light from other stars

• Due to chemical reactions on its surface

What causes the movement of continents?

• Wind and water erosion

• Plate tectonics

• Gravitational pull from the moon

• Volcanic eruptions

What is a quark?

• A unit of energy

• A small planet

• A fundamental particle that makes up protons and neutrons

• A type of dark matter
