| Galilei | Published strong evidence to support Heliocentric Model/Telescope |
| Newton | First to explain why planets and moons stay in orbit |
| Inertia | An object continues moving in a path until acted on by another force |
| Gravity | Force that attracts all objects to each other |
| Einstein | First to explain why Gravity has an effect on objects |
| relativity | The theory of _________ says time is the fourth dimension of space, and any object with mass actually warps space-time |
| Corona | Thin outer layer of the sun only seen during eclipses |
| Chromosphere | Swirling mass of flames and red light in the sun |
| Photosphere | Where light is released from the sun |
| Convective Zone | Where energy moves using convection in the sun |
| Core | center of the sun with the highest heat and pressure |
| Radiative Zone | area of the sun where energy radiates from atom to atom |
| Heliosphere | The sun's magnetic field |
| Sunspots | Pockets of strong magnetism on the sun |
| Rotation | The time it takes a planet to spin once on its axis |
| Revolution | The time it takes a planet to orbit around its star |
| Eccentricity | How oval or circular a planet's orbit is |
| Cancer | Tropic of _________ in the Northern Hemisphere |
| Capricorn | Tropic of _________ in the Southern Hemisphere |
| Solstice | When the sun reaches it's highest or lowest point in the sky |
| Equinox | When day and night are of equal time |
| Summer | When it is Winter in the Northern Hemisphere, it is this in the Southern |
| Giant Impact | __________ __________ Theory is the theory that A large protoplanet the size of Mars hit Earth during formation, and broke pieces off, which condensed into the Moon |
| Reflects | The Moon only ___________ light from the Sun. |
| Gibbous | The moon phase that is between 50-99% full |
| Lunar | The type of eclipse that happens when Earth prevents light from reaching the Moon |
| Solar | The type of eclipse that happens when the Moon prevents light from reaching the Earth |
| Tides | daily changes in sea level caused by gravitational pull of the Moon and Sun |
| Spring | The tides that happen when the moon is in line with the sun |
| Neap | The tides that happen when the moon is perpendicular to the sun |
| New moon | Moon is 0% full |
| Crescent | Moon is between 1% and 50% full |
| Quarter Moon | Moon is 50% full |
| Full Moon | Moon is 100% full |
| Waxing | getting bigger (more light) |
| Waning | getting smaller (less light) |
