What is everything that exists, including all matter and energy. The Universe In the core of the Sun, what is the process called where mass, in the form of hydrogen gas atoms combine and create Helium gas? Nuclear Fusion …………… ………are produced by the motion of electrically charged particles. These waves radiate from the electrically charged particles. They travel through empty space as well as through air and other substances. Electromagnetic waves Why does the Sun appear to rise and set each day? Because of Earth’s rotation on it’s axis. If the strength of the Sun’s magnetic field decreased, the temperature of the sunspots would……? Increase ! What is the distance from the sun to Earth One Astronomical Unit, or (93,000,000 miles. Abbreviated AU) What name is given to the Sun’s outer Atmosphere, that is so thin it can only be seen during a Solar Eclipse? Corona Areas of the sun that represent cooler spots are……..? Sunspots The Sun’s Atmospheric Layers Photosphere – Bottom Layer Chromosphere – Middle Layer Corona – Outer Layer What are the 3 layers of the Sun’s Atmosphere? The Photosphere What is the name of the layer where the sun's energy is released as light, and is visible to Solar Flare A ………. is defined as a sudden, rapid, outward eruption of electrically charged atomic particles. What surrounds the convective zone of the sun? ?????? What is the layer of the Sun’s interior where energy moves from atom to atom in the form of electromagnetic waves? What is the layer of the Sun’s interior where nuclear fusion takes place? What is the layer of the Sun’s interior where moving gases transfer heat energy that is carried to the surface? The Convection Zone The Sun’s Interior Layers 3. Outermost Zone ? 2. Middle Zone ? 1. Inner most ? Infrared radiation, visible light, ultraviolet radiation, are all part of this spectrum, and are in order, separated by increased frequencies and decreased wavelength? The Electromagnetic Spectrum Photosphere 1 Core 5 Sunspot 4 Corona 2 3 Solar Flare What is a huge collection of gas, dust, and billions of stars called? A Galaxy Sudden outward eruptions of electrically charged atomic particles from the sun are called? Solar Flares What do we call a group of stars that, when seen from Earth, form a pattern? A Constellation The Chromosphere This layer of the Sun emits a reddish glow as super-heated hydrogen burns off. The sun’s source of heat and light energy comes from what process involving what atom? Fusion of Hydrogen What would another name for the Northern and Southern lights be? A u r o r a s About how long does it take the sun’s light to reach the Earth? 8 Minutes The Sun, planets and their moons, and a large collection of smaller objects such as asteroids, comets, and meteors are together, called the…..? Solar System About how long does a sunspot cycle last? 11 years
