Solar Flares and CMEs Overview

The video tutorial discusses solar flares and coronal mass ejections (CMEs), explaining their characteristics and impacts. Solar flares are bursts of electromagnetic radiation from the sun, while CMEs involve large-scale ejections of plasma. Both phenomena can affect Earth, causing auroras and disrupting technology. The video also covers the classification of solar flares, highlighting the potential dangers of high-intensity flares.

What are solar flares primarily composed of?

• Plasma and electromagnetic radiation

• Solid particles

• Carbon dioxide

• Water vapor

What is the difference between a filament and a prominence?

• Filaments are bright, prominences are dark

• Filaments are on Earth, prominences are on the sun

• Filaments are gaseous, prominences are solid

• Filaments are dark against the sun, prominences are visible against space

What is a coronal mass ejection (CME)?

• A small solar flare

• A large explosion of plasma from the sun

• A minor solar event

• A type of solar wind

How do CMEs affect Earth's magnetic field?

• They have no effect

• They strengthen it

• They can cause magnetic storms

• They make it disappear

What natural phenomenon can be caused by particles from CMEs interacting with Earth's atmosphere?

• Volcanic eruptions

• Tornadoes

• Auroras

• Earthquakes

What was a significant impact of the 1989 solar storm in North America?

• Widespread power outages

• Massive earthquakes

• Increased temperatures

• Severe flooding

How are solar flares classified?

• By their duration

• By letter, indicating intensity

• By their color

• By their size

What does an X-class solar flare indicate?

• A very strong solar flare

• A non-existent solar flare

• A moderate solar flare

• A weak solar flare

What scale is used to measure the intensity of solar flares?

• Logarithmic scale

• Exponential scale

• Linear scale

• Geometric scale

What can happen to air traffic during a high-intensity solar flare?

• It can change direction

• It can be unaffected

• It can be grounded due to radiation exposure

• It can increase in speed
