100
Relative dating shows that rock layers closer to the surface are this age (younger or older).
What is younger?
100
Shown as an "H" on a weather map; pressure associated with good and clear weather.
What is High Pressure?
100

The deepest part of the ocean, where water pressure is greatest (starts with "t").

What is a trench?
100
Collection of rocks that are orbiting between Mars and Jupiter (two words: "a", "t").
What is the asteroid belt?
100
Property that can be discovered by dividing a sample's mass (from a balance) by its volume (from graduated cylinder) (starts with "d").
What is density?
200

Collapsed caves carved out of limestone by acid rain (water made acidic from dissolved carbon dioxide)  (starts with "s").

What are sinkholes?
200

Shown as an "L" on a weather map; pressure associated with bad weather and storms (like hurricanes, tornadoes, and thunderstorms).

What is Low Pressure?

200

The results of gravity of the Moon and Sun on ocean water (starts with "t").

What are the tides?
200
The cause of meteor showers on Earth, as it passes through the remains of this icy and rocky object (starts with a "C").
What is a comet?
200
Usage of crushed stone found in Virginia (starts with "c").
What is construction?
300

Circulation within the Mantle: material is heated by the core, rises, cools under the Crust, and sinks back to the core again (starts with "c").

What is convection?
300
Two forms of air masses on a weather map: one shown with blue triangles, the other with red circles.
What are Cold and Warm Fronts?
300
Causes of ocean currents (several correct answers).

What are density (denser water sinking), salinity (saltier water sinks), wind (pushes water), and temperature (colder water sinks)?

300
Location of Earth in the solar system (several correct answers).
Where are the inner planets, between Venus and Mars, the third planet?
300
The creation and movement of sediments through water, wind, ice, and biological activities. Two words: "w" and "e".
What are weathering and erosion?
400
Theory that describes how the Earth's lithosphere is broken into interacting pieces that produce volcanoes and earthquakes at their edges (two words: "p", "t").
What is the Theory of Plate Tectonics?
400

Effect of Earth's tilt (starts with "s").

What are seasons?
400

Shown through melted glaciers in temperate areas, this has varied through time; weather over much time (starts with "c").

What is climate?
400
Process of releasing energy through combining elements into larger atoms; occurs in the Sun (starts with "f").
What is fusion?
400

The ability of water to move through a layer or rock or clay (starts with "p").

What is permeability?
500

The process of a dense plate moving under another and melts; causes trenches and volcanoes (starts with "s").

What is subduction?
500

Drought (the lack of rain) and over-usage of groundwater through wells causes this underground surface of the zone of saturation to lower (two words, start with "w", "t").

What is the water table?
500

Tectonic boundary ("d") that causes ridges of volcanoes in middle of oceans as magma fills in between separating plates.

What is divergent?
500
Large stars explode in this stage to leave behind a neutron star or black hole (starts with "s").
What is a supernova?
500

Location in which intrusive igneous rock grains grow the largest because of slow cooling; insulated by ground.

What is underground?
