ALREADY GRADED A+ 2025 – 2026
felsic - ANSWERS-1-20% ferromagnesian silicates, typically have
biotite and amphibole, have 0-35% k feldspar, 25-50% plagioclase
country rock - ANSWERS-The rock surrounding and intrusive magma
body, much of it sometimes can break off and fall into the magma
in a process called stoping. tends to make magma more felsic if it
happens
stocks - ANSWERS-a large irregular shaped pluton which area is 100
kilometers square or less
,Batholiths - ANSWERS-a large irregular shaped pluton with an area
which is more than 100km's squared. Often is only formed when a
number of stocks coalesce beneath the surface to create one large
body.
plutons - ANSWERS-upward moving magma, which has cooled
within the crust. Can vary according to the shape and relationship
to the surrounding country rock
sill - ANSWERS-a slab of volcanic rock formed when magma
squeezes between layers of rock. is concordant (parallel) with
existing layering
dyke - ANSWERS-a slab of internal volcanic igneous rock which is
discordant and not parallel to the existing layering
the mantle - ANSWERS-made up of iron and magnesium silicate
materials. Most of the mantle which surrounds the outer core is
solid rock, but is plastic enough to be able to flow slowly.
Surrounding that part of the mantle is a partially molten layer, the
asthenosphere, and the outermost part of the mantle which is rigid.
Asthenosphere - ANSWERS-
Lithosphere - ANSWERS-
,tectonic plates - ANSWERS-
the crust - ANSWERS-Earth's outermost layer. mostly composed of
granite on the continents and mostly of basalt beneath the oceans.
Is rigid. The crust and the outermost rigid part of the mantle
together make up the lithosphere which is divided into about 20
tectonic plates that move in different directions on earth's surface
Geothermal gradient - ANSWERS-the temperature increases in the
earth with depth. approximately 30 Celsius a kilometer
convection - ANSWERS-the primary driving force for the movement
of tectonic plates. the transfer of heat from the core to the mantle
causing convection, as cold from the core goes down creating
circular heating/cooling patterns. Where convection currents in the
antle are moving upward, new lithosphere forms and the plates are
pushed apart
age of earth - ANSWERS-4,570 million years old
Phanerozoic Eon - ANSWERS-the last 542 million years in geological
time
mineral - ANSWERS-a naturally occurring combination of specific
elements arranged in a particular repeating three dimentional
structure
, Atomic number - ANSWERS-the number of protons in an atom
atomic mass - ANSWERS-the number of protons plus neutrons in an
atom
cation - ANSWERS-a positively charged ion (when an atom during a
reaction loses electrons)
anion - ANSWERS-A negatively charged ion, when during transfer
when an atom gains one or more electrons in order to become a
negatively charged ion
Lattice - ANSWERS-3d structure which represents a mineral and its
unique combination of specific elements.
Halite (NaCl) - ANSWERS-mineral, that is also known as salt.
Granite - Igneous - ANSWERS-H: 6-7, S.G. 2.6-2.7, Streak: white,
Luster: Dull to Grainy with Sporadic parts Pearly and Vitreous
Color: Black, Grey, Orange, Pink, White
Very hard, granular, crystalline igneous rock which consists mainly
of quartz, mica, and feldspar and is often used as building stone
