Auroras boreales: colores extraordinarios desde reacciones químicas

The video explains the phenomenon of auroras, which are stunning light displays visible at night. These occur due to the collision of solar particles with Earth's atmospheric atoms, resulting in light emission. The color of the aurora depends on the type of atom involved in the collision. The best places to observe auroras are near the poles, where Earth's magnetic field concentrates solar particles.

What is the initial cause of the aurora borealis phenomenon?

• The movement of tectonic plates

• The interaction between solar particles and Earth's atmosphere

• The collision of Earth's atmosphere with meteors

• The reflection of sunlight on ice

What happens to an electron when it is hit by a solar particle?

• It remains unchanged

• It moves to a lower energy level

• It disintegrates

• It jumps to a higher energy level

Which color is produced when solar electrons collide with oxygen atoms?

• Yellow

• Blue

• Green

• Red

Where are auroras most commonly observed?

• Near the equator

• At the poles

• In desert regions

• In tropical areas

Why are auroras more visible at the poles?

• Due to the concentration of solar particles by Earth's magnetic field

• Because of the cold temperatures

• Due to the presence of ice

• Because of the lack of sunlight
