axis
An imaginary line that runs from the North Pole to the South Pole, and it includes the center of Earth.
Coriolis effect
The apparent deflection of a freely moving object like water or air because of Earth's rotation.
Where do we live according to the hemispheres?
Eastern and Western
What would Earth's magnetic field be like if the planet was solid and why?
there would be no magnetic field
geocentric model
Model used by the ancient Greeks that puts the Earth at the center of the universe.
rotation
The motion of the Earth spinning on its axis.
What would happen to the winds if Earth didn't rotate?
there would be no winds
what would you say to someone that thought the earth was flat. in other words, what would you show them as proof
that there are pictures, and people have been in outer space
What important role does the magnetic field play for our planet?
serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer
heliocentric model
A model proposed by Copernicus that put the Sun at the center of the universe.
What is the tilt of Earth's axis of rotation?
23.5
the Coriolis effect is caused by what?
earths rotation
what are the hemispheres?
northern, southern, eastern, and western.
how is the magnetic field made
convection in the liquid outer core.
moon
A celestial object that orbits a planet.
How often does Earth rotate on its axis?
24 hours
what is the direction of deflection in the southern hemisphere
upwards and right
what evidence is there that the earth is flat?
that the pictures are not authentic
can the poles flip?
yes
revolution
The Earth’s movement around the Sun in an orbital path.
What will happen to the seasons in 13,000 years and why?
june will be winter and December will be summer
the Coriolis effect happens because the earth is rotating beneath a moving object?
true or false
true
