Earth surface (medium)
A large deposit of sand particles created by wind...
Heat that is transferred through space
radiation
A scientist who studies the atmosphere and predicts the weather
A geologic period when thick masses of ice from the higher latitudes move into the lower latitudes...
The Ice Age
A force of attraction that pulls objects toward each other...
Gravity
A moving mass of ice that forms across large geographic regions near the poles...
A continental glacier (if iceberg is answered, half points, if glacier is answered then that is fair.)
The large, single continental landmass that formed approximately 245 million years ago...
Pangea
A taiga biome
The curved path a celestial body takes to travel around another celestial body...
A moving mass of ice that forms at high altitudes on mountains...
An alpine glacier (if glacier is answered, that is fair.)
A boundary where two tectonic plates move away from each other...
A divergent boundary
An extremely large, tropical, rotating weather system that has winds of at least 119 km/h...
The climate zones greater than 66.5 degrees latitude north and south... (hint: the middle is tropical, after is the temperate, after is the...)
the polar zone
The moon phase when the near side of the Moon that is facing Earth is completely lit by the sun...
A full Moon
The very slow movement of soil and rock due to the pull of gravity...
A creep (downslide is not an allowable answer.)
The underwater mountain chain down the middle of the Atlantic Ocean basin that was formed by sea-floor spreading...
Mid-Ocean Range (Ocean range is acceptable)
A small weather system that has intense energy and creates heavy rains, high winds and lightning...
winds that blow mostly from one direction in a particular geographic region...
Prevailing winds
The counterclockwise rotation of a planet on its axis...
prograde rotation
A layer of rock that can both store ground water and allow it to move through the rock... (hint: it has the prefix aqua/aqui. Hint 2: water table.)
the aquifer
The northern continental mass formed when Pangaea broke apart approximately 180 million years ago...
Laurasia
A group of human-made chemicals that are known to breakdown ozone and cause atmospheric ozone depletion (hint: this is very difficult, it has elements in its name, carbon is in it, fluoro is in it, and chloro, is in it. NOT in order.)
Chlorofluorocarbons
The two days a year when the Sun's rays are most directly hitting the equator; neither hemisphere is tilted toward or away from the Sun... (hint: the earth is upright and being hit head on by the Sun's rays. hint 2: the word starts with E, ends with X)
