Outer Space and Celestial Bodies Quiz

Outer Space

• Outer space is the region of the universe beyond Earth's atmosphere.
• It is vast and largely a vacuum, containing celestial bodies such as stars, planets, and galaxies.

Meteor, Meteorite, Meteoroid

• Meteoroid: A small, rocky or metallic body traveling through space.
• Meteoroids are typically much smaller than asteroids.
• Meteor: A meteoroid that enters Earth's atmosphere.
• The intense heat generated from friction with the atmosphere causes the meteoroid to vaporize, creating a streak of light across the sky.
• This is often called a "shooting star."
• Meteorite: A meteoroid that survives its passage through the atmosphere and lands on the Earth's surface.
• Meteorites are valuable to scientists because they can provide samples of material from asteroids and other celestial bodies.

Sun Part Labeling

• Core: The central region of the Sun, where nuclear fusion converts hydrogen into helium, releasing enormous amounts of energy.
• This energy fuels the processes throughout the Sun.
• Radiation Zone: A region surrounding the core where energy is transported outward primarily through radiation (a transfer of electromagnetic energy).
• Convection Zone: The outermost layer of the Sun's interior.
• In this zone, energy is transported outward primarily by convection (the rising and falling of hot and cool gas).
• Photosphere: The visible surface of the Sun.
• It's a layer of relatively cool gas, appearing as a bright yellow disk with granular structure called granulation.
• Chromosphere: A thin layer above the photosphere.
• It appears reddish and is best seen during a solar eclipse.
• Corona: The outermost layer of the Sun's atmosphere.
• It's extremely hot and extends millions of kilometers out into space.
• This is the source of the solar wind, a stream of charged particles.
• Solar Flares: Violent eruptions on the Sun's surface, often associated with sunspots.
• They release large amounts of energy and particles into space.
• Prominences: Large, bright, cloud-like structures of plasma extending outward from the Sun's surface, often along the lines of magnetic fields.
• Sunspots: Relatively cool, dark areas on the photosphere that are associated with intense magnetic fields.
• They are often found in groups and their appearance and activity cycles.
