This is the measure of how bright a star would be if located 10 parsecs from Earth
What is Absolute Magnitude?
100
This is a permeable layer of rock and sediment that stores and carries groundwater in sufficient quantity to supply wells.
What is an aquifer?
100
This is a clay-like substance made of aluminum oxides and hydroxides; it is the chief ore of aluminum.
What is bauxite?
100
This is a type of vaporization of a liquid that occurs from the surface of the liquid into a gaseous phase that is not saturated
What is evaporation?
100
This is soil that formed from parent material left by winds, rivers, glaciers, or soil that itself was moved from its original location.
What is transported soil?
200
This is the temperature at which saturation occurs and condensation begins; it is a measure of the amount of water vapor in the air.
What is dew point?
200
These are different words that both mean a large underground chamber.
What are cavern and cave.
200
This is a white or colorless mineral consisting of calcium carbonate; it is a major constituent of sedimentary rocks such as limestone, marble, and chaulk.
What is calcite?
200
The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor
What is transpiration
200
This is the distance light travels in one year (9.5 trillion kilometers)
What is a light-year?
300
This is the value at which the universe is at balance and expansion is stopped.
What is critical density?
300
This is a combustible (can catch fire) black or dark brown rock consisting mainly of carbonized plant matter; widely used as a fuel source.
What is coal?
300
This type of rock is formed through the cooling and solidification of magma or lava.
What is igneous rock?
300
This is the rapid cycling of water vapor into the atmosphere by evaporation from the Earth's surface or rapid transpiration from plant leaves.
What is evapotranspiration?
300
This is a break in the lithosphere along which movement has occurred.
What is a fault?
400
This is a straight line passing from side to side through a body or figure, especially a circle or sphere.
What is diameter?
400
This is the area of a seabed around a large landmass where the sea is relatively shallow compared with the open ocean.
What is a continental shelf?
400
This type of rock is formed through the deposit and solidification of material transported by water, ice, and/or wind. Limestone and shale are common types of this rock.
What is sedimentary rock?
400
This is the pattern a mineral's ions or atoms form if there is enough time and room to grow; they are arranged in an orderly pattern that repeats over and over.
What is crystal shape.
400
This is a mass of rock, ice, dust, and gas traveling around the sun, usually in a highly irregular orbit.
What is a comet?
500
This is the amount of water vapor in the air at a given time and place.
What is humidity?
500
This is a technique that involves the use of a special hollow drill to remove cylindrical samples from sediment or rock for analysis.
What is core sampling?
500
This type of rock was once one form, but was changed to another form due to the influence of heat, pressure, or some other agent without passing through a liquid phase.
Marble is this type of rock.
What is metamorphic rock?
500
This is the final life stage of an extremely massive star, with a gravitational field so intense that not even light can escape from it.
What is a black hole?
500
This is the tendency of a mineral to split along planes of its crystalline structure where bonds are weakest.
