What are the Northern Lights?

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

• Auroras in the Northern Hemisphere

• A type of cloud formation that occurs at high altitudes

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

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

• The Sun's light reflects off the Earth's surface and creates the auroras

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

• Solar flares from the Sun are taken to the Earth by solar winds and those particles that interact with the Earth's magnetic field

• The Sun's gravity pulls the Earth closer to the auroras

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

• The Earth's magnetic field repels the solar wind particles guiding them towards the poles.

• The Earth's magnetic field has no effect on the production of auroras

• The Earth's magnetic field attracts the solar wind particles

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

Explain why the auroras have different colors?

• The colors of the auroras are a result of the Earth's magnetic field

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

• The colors of the auroras depend on the time of day they occur

• The colors of the auroras are caused by the different gases in the Earth's atmosphere at different altitudes.

Describe a mythological story or legend associated with the auroras. Why did the people think this?

• Ancient people believed that the auroras were fish that were swimming to light the way for struggling fish

• Ancient people believed that the auroras were a sign of impending doom

• Ancient people believed that the auroras were caused by dragons breathing fire

• Ancient people believed that the auroras were a reflection of the gods' anger

When and where would you see the auroras the best?

• During the day in the tropics

• During the night in the polar regions

• During the day in the polar regions

• During the night in the tropics

What is the main cause of the Earth's magnetosphere?

• Solar Winds

• Metal at the Poles
