QuestionAnswer
This theory claims that the earth is at the center of the universe geocentric theory
According to the geocentric theory, a planet did not orbit with the earth exactly at the center of its circular path. A circular path around an object located at the at a point other than the center of the circle eccentric orbit
The man who probably played the largest role in attempting to improve the geocentric theory Ptolemy
The main crystal spheres on which planets travel; proposed in the geocentric theory deferent
A modification to the geocentric theory to account for the temporary backward movement of the planets epicycle
Two major objections to the geocentric theory inaccuracy and complexity
This brought a rebirth of interest in culture including science Renaissance
According to this theory, the sub is the center of at least the solar system heliocentric theory
An astronomer who played a major role in the development of the heliocentric theory Nicholas Copernicus
The sun and all other heavenly bodies that revolve around it solar system
To an observer on Earth, another planet may seem to go backward in its orbit because the earth is traveling ____ in its orbit than the other planet faster
The Christian astronomer who formulated the three laws of planetary motion Johannes Kepler
Kepler’s major contribution to the Copernican heliocentric theory about the planets orbits elliptical orbits
Kepler believed that the primary goal of science is to lead men to God
The first person to use a telescope for astronomy Galileo
The English mathematician and scientist who formulated the law of universal gravitation Isaac Newton
Described the forces of attraction between masses of objects; force that holds planets in their orbits universal gravitation
Three physical factors that determine the force of gravity the mass of one of the objects, the mass of the other object, the distance between their centers of mass
The more massive a body is, ________ it has for another body greater gravitational attraction
If more massive heavenly bodies orbited less massive bodies, this would contradict the law of gravity
Earth’s movement around the sun revolution
Earth revolves around the sun and rotates on its axis
The line defined by an object’s rotation axis
The tendency for bodies in motion to remain in motion in the same direction at constant speed inertia
Earth is flattened at its poles
Earth is bulged at its equator
Of all the planets, why are Jupiter and Saturn the most bulged at the equator fastest spinning planets
Deflection of projectiles and the winds show that the earth is rotating
The Foucalt pendulum would not be deflected at all if it were located here equator
Evidence of the earth’s rotation is found in diagonal wind patterns, earth’s bulging equator, behavior of a Foucault pendulum
Most recent evidence that established that the earth moves and not the sun direct observation
How was the earth’s rotation observed directly astronauts on the moon saw the earth’s entire surface in each twenty four hour day
The path the sun appears to follow among the stars ecliptic
The angle between the earth’s axis and a line perpendicular to the plane of its orbit 23.5 degrees
During summertime in the Northern Hemisphere, the North Pole is tilted towards the sun
Could be used as evidence of the earth’s revolution occurrence of seasons
When it is summer in the Northern Hemisphere, it is ____ in the Southern Hemisphere winter
A day in which the sun’s overhead noon position appears to be directly above the equator equinox
How do day and night compare on the dates of the equinoxes day and night are equal lengths in all parts of the earth
A day which the apparent movement of the sun reaches its northern-most or southern-most limit solstice
The apparent shift in position caused by a change in the position of observation parallax
These are observed more often on the leading side of the earth in its orbit meteors
An astronomer’s observations and the theories he suggests depend on vantage point in the universe
