A tool used to view the planets from Earth
Telescope
The two factors that can change the gravitational pull between two objects.
mass and distance
This is the number of seasons we experience in a year.
4
This is the vertical invisible line of which the Earth rotates around, and it's tilted.
the axis
What does heliocentric mean?
Sun-Centered
Earth's rotation and revolution are in this direction
Counter Clockwise
The sun is the center of our solar system because
it has the most mass so it has the most gravity
These are the names of the four seasons
winter, spring, summer, fall/autumn
If a rotation of Earth gives us days and nights, what gives us years and seasons?
a revolution
What does geocentric mean?
Earth centered
The two days a year where day light and night time are equal
Equinox
When I travel to the moon one measurement of my body will change and one will stay the same. Name the measurement that will change.
weight
This angle of Earth causes different seasons.
tilt (23.5 degrees)
This term reflects the turning of an object around a single point or axis.
rotation
Who developed a stronger telescope and observed Jupiter's moons?
Galileo
The two resources we need from the sun to survive
light and heat
Objects falling on the moon hit the ground at the same time, while on earth this factor makes objects hit the ground at different times.
air resistance
This invisible line divides the Earth into a northern and southern hemisphere.
the equator
These are the two factors to change a planet's orbit
Mass and Distance
Who used the new information provided by the telescope to develop a heliocentric theory?
Copernicus
The speed of gravity's acceleration to Earth's surface
9.8 m/s^2 or 9.8 m/s/s
The term used to describe the outside of an object that is exposed to air, or why a belly flop won't allow you to sink into a pool.
Surface Area
These two seasons have indirect, less concentrated sunlight because of a sideways tilt of Earth to the sun
spring and fall
This is the EXACT amount of days it takes Earth to revolve around the sun one time
365 (1/4)
Who presented the theory of a geocentric solar system?
Ptolemy
