100
The difference in the date
What is Varience
100
This is a Supercontinent when all Earth land was connected 200 million years ago
What is Pangaea
100
This is a metal sphere which is lowered on cables to the deep ocean floor
What is Bathysphere
100
This is 78%- plants use nitrogen as nutrients
What is Nitrogen
100
the universe is expanding as all galaxies move apart
What is Hubble law
200
This is a proposed explanation
What is Hypothesis
200
This is a Super ocean surrounding Pangaea 200 million years ago.
What is Panthalassa
200
This is the deepest features on the earth, found where subduction occurs
What is Trenches
200
This is the surface layer - very warm, contains all weather and life on Earth
What is Troposphere
200
This is the massive sphere of gasses that produces its own energy
What is a star
300
This is a conclusion that doesn't have 100% proof but is accepted to be true
What is law
300
This is heated material in the asthenosphere rises and sinks as it becomes hotter and colder. This causes the plates above to move
What is Convection currents
300
This is the flat-topped seamounts from erosion of waves (covered up islands)
What is guyots
300
This is gasses allow sunlight to heat the earth and then they hold onto the heat (infrared energy)
What is The green house effect
300
This is spheres of matter that are smaller than planets and revolve around planets
What is the moon
400
This is Slightly wider at the equator, due to faster rotation
What is oblate spheroid
400
This is when one plate moves under one another causing magma to be produced and makes volcanoes
What is subduction
400
This is the Amount of salt is dissolved in water, listed in ppt (parts per thousand) Average is 35 ppt
What is Salinity
400
This is cold air mass moving into a hot air mass- produces heavy rains and sometimes storms
What is cold front
400
This is "dirty snowballs" made of frozen gasses and debris, typically have large, irregular orbits
What is comets
500
This is Earth traveling around the sun once in a year.
What is revolution
500
This is made from a collection of smaller rocks or sand
What is Clastic
500
This is the weaker high and low tides due to perpendicular alignment of the sun, moon, and earth
What is neap tides
500
This is when is forms over land at the poles = clouds or precipitation if humidity is present
What is continental polar
500
this is the plant that has a horizontal rotation
What is neptune
