What are island arcs commonly made of? --CORRECT ANSWER--
Basalt
What ozone layer benefits humans? How? --CORRECT ANSWER--
The Stratosphere protects humans from radiation
Cloud Types --CORRECT ANSWER--Cumulonimbus -
thunderstorms
Cumulus - white, cotton-like, fluffy clouds
Cumulostratus - thin clouds at a high altitude
Stratus - thin clouds at a low altitude, fog
(sometimes produces a drizzle of flurry)
Page 1 of 38
,El Nino --CORRECT ANSWER--a natural phenomenon when the
clouds of the Eastern Pacific are minimal and the ocean becomes
significantly warmer; thus causing increased evaporation and
condensation
Fjord --CORRECT ANSWER--A long narrow inlet with steep cliffs
created by glacial erosion (commonly found in Washington State)
The Alps were formed... --CORRECT ANSWER--...by the collision
of the African and Eurasian continents (the alps are not made of
volcanic rock)
Three Main Types of Rocks --CORRECT ANSWER--Igneous -
Obsidian, Basalt, Granite (made from lava/ volcanic activity)
Metamorphic - Slate, Gneiss, Phyllis (made under extreme pressure
and temperature)
Sedimentary - Limestone, Shale, Sandstone (made from weathering
and erosion)

,Convergent Boundary --CORRECT ANSWER--when two tectonic
plates run into one another, causing one to slide beneath the other
Divergent Boundary --CORRECT ANSWER--when two tectonic
plates pull away from one another, causing a "tear"
Transform Faults --CORRECT ANSWER--when two tectonic plates
slide next to one another horizontally
Hot Spot --CORRECT ANSWER--when a lava melts through the
crust, causing a volcanic eruption
Estuary --CORRECT ANSWER--where the mouth of a river/ stream
meets the ocean (an area for diversity in wildlife and an excess of
nutrients)
Playa --CORRECT ANSWER--a large basin that remains when all
the water evaporates out of a lake
Three Characteristics of Braided Rivers --CORRECT ANSWER--1.)
High-level of sediment
Page 3 of 38
, 2.) High width-to-depth ratio (it is wide and shallow)
3.) The banks of the river are extremely erodible
A 400g cart moving at 12 cm/s collides with a still cart that weighs
800g. What speed are they both traveling at now? --CORRECT
ANSWER--4 cm/s
Electromagnetic Spectrum --CORRECT ANSWER--Radio --
Microwave -- Infared -- Visible -- Ultraviolet -- X-ray -- Gamma
Mnemonic Device: Red Martians Invaded Venus Using X-ray Guns
Coulomb's Law --CORRECT ANSWER--The relationship between
distance and attraction/repulsion in electricity
Like charges repel more strongly as they move closer to one another
Unlike charges attract more strongly as they move close to one
another
