Astronomy Quiz

What are the Northern Lights? How are they formed?

• A phenomenon caused by the reflection of sunlight off the moon's surface

• A natural light display in the Earth's sky, predominantly seen in the high-latitude regions

• A result of volcanic activity deep within the Earth's core

• A type of cloud formation that occurs in the upper atmosphere

What is the magnetosphere?

• A sphere of magnets

• The Earth's magnetic field due to iron core

• It's what holds everything down on the Earth

What is the Sun's role in the production of auroras on Earth?

• The Sun's gravity pulls charged particles towards the Earth's poles

• The Sun emits a solar flare that is carried to the Earth by solar winds

• The Sun's heat causes the Earth's atmosphere to glow

• The Sun's magnetic field interacts with the Earth's magnetic field to create colorful lights

What is the Earth's magnetic field's role in the production of auroras on Earth?

• The Earth's magnetic field reflects sunlight towards the poles

• The Earth's magnetic field traps charged particles from the Sun and they move towards to poles

• The Earth's magnetic field generates heat that causes the atmosphere to glow

• The Earth's magnetic field creates a barrier that prevents auroras from occurring

Explain why the auroras have different colors?

• The colors of auroras are determined by the temperature of the Earth's atmosphere

• The colors of auroras are caused by the reflection of sunlight off the moon's surface

• The colors of auroras are determined by the type of gases in the Earth's atmosphere

• The colors of auroras are caused by the interaction of the Earth's magnetic field with the solar wind
