Science Chap. 2 Sec. 2

Nuclear Fusion The process in which hydrogen atoms join together to form helium, releasing energy
Core The central part of the sun where nuclear fusion occurs.
Photosphere The inner layer of the sun's atmosphere.
Chromosphere The middle layer of the suns atmosphere.
Corona The outer layer of the sun's atmosphere.
Solar Wind A stream of electrically charged particles produced by the sun's corona.
Sunspot An area of the sun where the gas on the surface is cooler than the gas surrounding it.
Prominence A loop of gas connecting sunspots.
Solar flare An explosion of hydrogen gas from the sun's surface that occurs when sunspot regions suddenly connect.
How is energy produced in the sun's core? Through nuclear fusion, turning hydrogen into helium.
Name the three layers of the sun's atmosphere Photosphere, Chromosphere and Corona.
Name three features found on the surface of the sun. Sunspots, prominences, and solar flares.
Why do sun spots look darker than the rest of the sun's photosphere? Sunspots are areas of cooler gas, and cooler gas gives off less light.
How do sunspots change over time? By the changes in climate on earth.
What is a solar flare and how can it effect us? Solar flares occur when the gas on the surface of the sun explodes and connects sun spot regions. How it effects us is that when a solar flare occurs it gives off a lot of solar wind, which can effect us at the poles more than anywhere else by creating m
