5 Science Chapter 7
sphere of light; the surface layer of the sun; the layer visible to the observer on Earthni
the sun's atmosphere that has a colorful layer of gases that surrounds the sun's photosphere; visible only through a monochromator
a vapor blanket that surrounds the chromospheres and extends to about 249,000miles from the surface of the sun; visible only during a total solar eclipse
the blocking out of the sun's light that occurs when the moon comes between the sun and the earth
the obscuring of the moon that occurs when the earth comes between it and the sun; the moon is temporarily darkened as it passes through the earth's shadow
the pressure of atmospheric or compressed air; the total weight of air on some particular place on earth
the layer of gases surrounding a planet or moon;
a form of oxygen with three atoms of oxygen in its molecule instead of the two atoms found in in molecules of normal oxygen gas
a light visible on the horizon on especially dark and clear nights; cast by ions created when solar rays strip electrons from electrons from atoms of gases in the upper atmosphere
small solid pieces of rocky debris traveling through space; many meteoroids are fragments broken off asteroids
an atom that is either positively charged because it has lost some or all of it electrons, or negatively charged because it has picked up one or more extra electrons
a steady stream of subatomic particles speeding outward from the sun and through space at a million miles per hour
light display seen near the poles caused by the collisions of particles from the solar wind with molecules of air
How far away is the sun?
Layer of Earths's atmosphere closest to the Earth where weather occurs
Where do sunspots occur?
on the photosphere
the first phase after a new moon
meteoroids burn up in this layer
the first planet discovered in modern times. It was discovered by Sir Wm Herschel. It rotates on it's side.
largest planet with the big red spot
Earth's twin and brightest planet in the sky
planet with 7 rings and over 60 moons
royal blue planet where the wind blows hardest. It has a moon named Triton.
only planet suitable for life.
planet closest to the sun
the red planet.
innermost section of the sun
darker areas on the outer surface of the sun
where the light of the moon comes from
78% of the air is made of this gas
layer in the stratosphere that helps protect the earth from ultraviolet rays
topmost layer of the earth's atmosphere
scarce; thin and less dense
earth is surrounded by this field that protects it from harmful space particles
the northern lights
percent of nitrogen in the earth's air
