Updated | 100% Correct
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
The atmosphere is composed of - ANSWER- 78% nitrogen
21 % oxygen
List earths atmosphere layers in order from lowest to highest. - ANSWER- Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
Moon phase: waxing - ANSWER- Two weeks where the moon goes from a new moon to a full
moon
After a full moon the moon is - ANSWER- Waning
What type of cells are animal and plant cells - ANSWER- Eukaryotic
Eukaryotic cells have a - ANSWER- Nucleus
Mendels laws are the laws of - ANSWER- Segregation (each parent contributes half) and the
law of independent assortment (traits are passed randomly)
Natural selection - ANSWER- The theory developed by Darwin that traits help give a species a
survival advantage are passed on to generations
Heterotrophs - ANSWER- feed off of a host
can only consume food/ cannot produce their own
the number of protons in the nucleus determines - ANSWER- the atomic number of the
element
atoms with neutral charge have an atomic number that is equal to - ANSWER- the number of
electrons
Atomic mass (A) - ANSWER- total number of protons(Z) and neutrons(N) in the nucleus
A= Z+N
Boyle's law - ANSWER- Gases contract when pressure is applied to them
