PRAXIS 5005 EXAM QUESTIONS WITH
VERIFIED SOLUTIONS
Igneous Rock - ANSWER-formed when hot magma cools beneath the ground
or
lava cools above the ground
forms crystal like/ glassy rocks
ex: granite, pumus, basalt
Sedimentary Rock - ANSWER-Changed by pressure
does not involve heat
Usually near water/ involves water
sometimes contain fossils
forms from previously weathered and erroted material which may have been igneous,
sedimentary, rock metamorphic rock.
ex: dolemite, limestone, sandstone
Metamorphic Rock - ANSWER-Has been changed by great heat and pressure
altered, partially remelted
ex: slate, marble
Plate tectonic theory - ANSWER-Lithosphere is made up of major and minor plates
Sit on viscous (thick fluid) part and move with it
Three types of plate boundaires - ANSWER-1. Transform boundaries: they slide past
each other causing friction/ earthquakes
2. Divergent boundaries: two plates that pull away from each other/ creates new crust
3. Convergent boundaries: plates push into each other/ one goes under called
subduction
Main causes for extinction - ANSWER-Climate change & Habitat destruction
If earth began 12 midnight & it is currently 11:59, when did humans arrive? - ANSWER-
11:59
Traits pass through - ANSWER-proteins?
, weathering - ANSWER-The breaking down of rocks and other materials on the Earth's
surface.
Erosion - ANSWER-the process of eroding or being eroded by wind, water, or other
natural agents.
Volcanoes - ANSWER-an opening in the Earth's crust through which molten lava, ash,
and gases are ejected.
earthquakes - ANSWER-sudden, violent movements of Earth's crust
current - ANSWER-A large stream of moving water that flows through the oceans
Tides - ANSWER-the regular rise and fall of the ocean's surface influenced by the
moon's gravity pulling on earth
water cycle - ANSWER-The continuous process by which water moves from Earth's
surface to the atmosphere and back
Evaporation - ANSWER-The change of a substance from a liquid to a gas
humidity - ANSWER-The amount of water vapor in the air
Precipitation - ANSWER-the falling to earth of any form of water (rain or snow or hail or
sleet or mist)
surface runoff - ANSWER-water that flows over land until it reaches lakes, rivers, or
other areas
Minerals - ANSWER-Nutrients that occur naturally in rocks and soil
organic material - ANSWER-Materials that were once part of living things
living organisms in soil - ANSWER-soil microorganisms play essential roles in the
nutrient cycles that are fundamental to life on the planet.
Nutrients - ANSWER-a substance that provides nourishment essential for growth and
the maintenance of life.
Crust - ANSWER-The thin and solid outermost layer of the Earth above the mantle. The
crust is cool, solid rock that floats on the denser rock beneath.
Mantle - ANSWER-The layer of hot, solid material between Earth's crust and core. The
mantle is hot, but not enough to melt rock into a liquid. Instead, the material here is like
hot Play-Doh. It can move, but only very slowly.
