Term | Definition |
---|---|
atmosphere | the mixture of gases surrounding a planet |
biosphere | all the living things on a planet |
channel | a long, narrow groove that forms where water, lava, or other liquid flows |
claim | a proposed answer to a question about the natural world |
climate | general weather patterns over a long period of time |
compare | to notice how two or more things are alike or different |
crescent moon | a moon phase that looks like less than a half circle from Earth |
energy | the ability to make things move or change |
evidence | information about the natural world that is used to support or go against (refute) a claim |
exomoon | a moon outside of our solar system |
exoplanet | a planet outside of our solar system |
full moon | a moon phase that looks like a full circle from Earth |
geosphere | the solid part of a rocky planet |
gibbous moon | a moon phase that looks like more than a half circle from Earth |
habitable | having the conditions necessary to support life |
hydrosphere | all the liquid water and solid water (ice) on a planet |
illuminate | to shine light on an object and make it visible |
model | an object, diagram, or computer program that helps us understand how a system, or part of a system, works |
moon | a rocky sphere that travels around a planet |
new moon | a moon phase where the Moon is not visible from Earth |
ocean current | ocean water flowing in a continuous path |
orbit | the nearly circular path a smaller object (like the Moon) travels around a larger object (like Earth) |
pattern | something we observe to be similar over and over again |
prevailing winds | winds that move in one direction and are strong enough to push ocean currents |
quarter moon | a moon phase that looks like a half circle from Earth |
reasoning | the process of making clear how your evidence supports your claim |
scale | the relative size of things |
scientific argument | a claim supported by evidence |
solar system | the sun, the planets that orbit the sun, and other objects that orbit the sun |
system | a set of interacting parts forming a complex whole |
sun | the star that is the main source of light at the center of our solar system |
temperature | a measure of how hot or cold something is; the higher the temperature is, the more energy it has. |
terminator | the border between light and dark on the Moon |
transfer | to move energy from one object to another or one place to another |
year | the amount of time it takes for a planet to complete one orbit around a star or stars |
cause | an event or process that leads to a result or change |
claim | a hypothesis |
effect | a result or change that happens because of an event or process |
El Niño | a climate pattern where water near the equator gets hotter than usual and affects the weather around the world; El Niño happens in the Pacific Ocean |
gyre | a giant pattern of moving water that spans whole oceans and moves water from place to place in a circle |
latitude | the distance of a place north or south of the Earth's equator |
