Cards

Term
apparent magnitude
Definition
how bright a star appears when viewed from Earth.
Term
earth science
Definition
the 4 main sub categories of Geology, Astronomy, Oceanography, and Meteorology.
Term
observations
Definition
the use of the senses to gather and record information.
Term
expansion
Definition
was predicted by the Big Bang theory and helps establish the rate of expansion for the universe.
Term
red shift
Definition
The concept that the more distant an object is in space, the farther in its past we are observing its light
Term
expansion
Definition
the universe is both infinitely large and eternal, and space is neither expanding nor contracting.
Term
hertz Russel diagram
Definition
shows the relationship between a stars brightness and its temperature.
Term
astrophysics
Definition
The branch of astronomy devoted to the study of the physical characteristics and composition of objects in the sky
Term
jovian plaets
Definition
composed of liquid and frozen gases and orbit outside the asteroid belt.
Term
scientific law
Definition
A statement about what happens in nature that seems to be true 100% of the time
Term
nebula
Definition
used to describe objects believed to be fuzzy patches of luminous gas and dust
Term
nova
Definition
gets several thousand times brighter in a few days, and then fades to its original brightness over several months.
Term
natural science
Definition
includes all fields of natural science related to the planet we live on.
Term
senses
Definition
include the use of sight, hearing, or touch.
Term
cosmology
Definition
Answers sought by this field include; How did the Universe begin? When did it begin? Where did it come from? and How will it end?
Term
red giants
Definition
100 to 1000 times the size of the sun.
Term
geoscience
Definition
The science that deals with the earth's physical structure and substance, its history, and the processes that act on it
Term
theory
Definition
what a scientist believes is most likely true
Term
metaphysics
Definition
exploring the fundamental questions, including the nature of concepts like being, existence and reality.
Term
Binary stars
Definition
A pair of stars that are bound together by gravity
Term
corona
Definition
The continuous flow of charged particles released from the upper atmosphere of the Sun
Term
Galaxies
Definition
other galaxies outside our own galaxy.
Term
scientific theory
Definition
A suggested, testable answer to a well-defined scientific question
Term
absolute magnitude
Definition
the amount of light that a star actually emits
Term
geological science
Definition
the branch of geology that studies the materials, structure, and surface features of the earth and the geologic processes that form them.
Term
doppler effect
Definition
a light source that is moving away from the observer.
Term
model
Definition
makes things easier to visualize and understand.
Term
background radiation
Definition
This radiation is left over from an early stage of the universe like a distant flash from the Big Bang itself.
Term
supergiant
Definition
very large, cool, bright star.
Term
terrestrial planets
Definition
Mercury, Venus, Earth, and Mars are made of rock and dust
Term
experiment
Definition
the validity of a given hypothesis.
Term
Main sequence
Definition
When plotted on a graph that compares surface temperature to brightness, most stars with average mass, lie within a narrow band which crosses the graph diagonally from lower right to upper left
Term
big bang
Definition
the sun and planets condensed out of a large rotating cloud of dust and gas.
Term
physical object
Definition
something that is too complex, difficult or dangerous to observe or test directly.
Term
matter
Definition
Faster expansion of the universe would have produced more matter
Term
nova
Definition
means “new star”.
Term
red
Definition
the color of the longest wavelength
Term
geological history
Definition
The branch of Geology that tries to reconstruct the geologic events of Earth's past
Term
look back time
Definition
The amount by which you look into the past is equal to the distance to the galaxy measured
Term
delta Cepheid
Definition
this star brightens and then fades in a regular repeating pattern over time.
Term
relativity
Definition
first proposed and supported by Einstein.
Term
nebula
Definition
A large cloud of gas and dust in space
Term
factor
Definition
This is the “Effect” in a cause and effect relationship.
Term
supernova
Definition
Stars with very high mass expand into a supernova
Term
atmospheric science
Definition
the studies of the composition, processes and phenomena of the atmosphere.
Term
dependent variable
Definition
controlled and changed by the experimenter in order to see how it effects other factors.
Term
light-year
Definition
The distance a beam of light would cover in 1 year
Term
oceanology
Definition
The science that includes everything from the composition and movements of sea water to the plants and animals that live in it.
Term
structural geology
Definition
always in numeric (number) form.
Term
Big Bang
Definition
The current theory of how our solar system formed
Term
data
Definition
Recorded observations or items of information
Term
center of mass
Definition
orbit around a mutual fixed point in space called the center of mass.
Term
constellation
Definition
A formation of stars, like Orion or The Big Dipper
Term
astronomy
Definition
The science that studies celestial objects, space, and the physical universe outside of our planet.
Term
dependent factor
Definition
responds to changes in another factor.
Term
parrallax
Definition
used to measure distances to things that are relatively close. Large distances are measured in parsecs.
Term
meteorology
Definition
primary focus is forecasting the weather.
Term
observations
Definition
describe actions, color, textures, and other traits not easily measured.
Term
