Weather Things: Aurora and Unique Phenomena

The video explores various atmospheric phenomena, including the aurora borealis, the colors of snow and glaciers, and the creation of mirages. It explains how light interacts with the atmosphere, ice crystals, and water droplets to produce these effects. The video also discusses how these phenomena help meteorologists understand weather patterns and atmospheric conditions.

What causes the aurora borealis to appear in the sky?

• Scattering of blue light in the atmosphere

• Reflection of sunlight by ice crystals

• Absorption of light by water droplets

• Interaction of high-energy particles from the sun with the atmosphere

Why do glaciers often appear blue?

• The presence of blue minerals in the ice

• Blue light is scattered the most in glacial ice

• They absorb all colors except blue

• They reflect only blue light

How does a mirage form on a hot roadway?

• Light bends due to temperature differences and air density

• Light is absorbed by the road surface

• Light is reflected directly from the road

• Light is scattered by dust particles

What causes the sun or moon to appear flattened when rising or setting?

• The reflection of light by water bodies

• Light from the top of the disk travels faster than from the bottom

• The presence of clouds in the atmosphere

• The curvature of the Earth

How do atmospheric colors help meteorologists?

• By predicting rainfall patterns

• By gauging moisture, cloud height, and air stability

• By measuring air pressure

• By determining wind speed
