Meteoroids - ANSWER Small bodies of debris from space which move into Earth's atmos-
phere and can then turn into meteors
Maritime Polar Air Mass (mP) - ANSWER A cold, moist air mass that formed over polar
oceans
Hot Spring - ANSWER A geological feature produced when water is heated by geothermal
activity and pushed to Earth's surface
Nutrients - ANSWER Substances in food and beverages that nourish the living things.
They support growth, produce energy, and maintain the organism
Streak - ANSWER The color of the mineral in powder form; obtained by dragging a piece
of the mineral across a piece of unglazed porcelain
Thermosphere - ANSWER A very thin layer of atmosphere which has high temperatures;
contains the ionosphere and exosphere
Specific Gravity - ANSWER The ratio of the density of the mineral to the density of water
Tenacity - ANSWER The mineral's ability to resist separation or breaking when subjected
to stress
Constructive Processes - ANSWER Processes that add new landforms to the surface of
the earth
1
, Taste - ANSWER The mineral's taste; only soluble minerals have a taste
Global Warming/Climate Change - ANSWER An overall increase in average global temper-
ature due to the greenhouse effect (the increasing amount of carbon dioxide in Earth's at-
mosphere trapping more heat)
Organic Material - ANSWER Dead plant and animal material in the soil
Metamorphic Rock - ANSWER Form when rock is subjected to great heat and pressure;
banding or stripes
Ionosphere - ANSWER A layer of ions and free electrons in the atmosphere; can reflect
and direct radio waves
Igneous Rock - ANSWER Rocks formed when magma or lave cools; air pockets or crystals
Troposphere - ANSWER The layer of gases closest to the earth where weather occurs
Nuclear Fission - ANSWER A process in which the nuclei of an atom is split, releasing a
massive amount of energy
Mineral - ANSWER A naturally occurring, inorganic solid with an orderly, network struc-
ture and definite chemical composition
Ozone Layer - ANSWER A layer of ozone in the stratosphere that blocks harmful ultravio-
let radiation from reaching the earth's surface
