TeXes Science 7-12 Practice Test Questions Solved
Correctly to Pass
Fjord - Answer A long narrow inlet with steep cliffs created by glacial erosion (commonly found in
Washington State)
The Alps were formed... - Answer ...by the collision of the African and Eurasian continents (the alps are
not made of volcanic rock)
Three Main Types of Rocks - 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)
What are island arcs commonly made of? - Answer Basalt
What ozone layer benefits humans? How? - Answer The Stratosphere protects humans from radiation
Cloud Types - 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)
,El Nino - 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
Convergent Boundary - Answer when two tectonic plates run into one another, causing one to slide
beneath the other
Divergent Boundary - Answer when two tectonic plates pull away from one another, causing a "tear"
Transform Faults - Answer when two tectonic plates slide next to one another horizontally
Hot Spot - Answer when a lava melts through the crust, causing a volcanic eruption
Estuary - Answer where the mouth of a river/ stream meets the ocean (an area for diversity in wildlife
and an excess of nutrients)
Playa - Answer a large basin that remains when all the water evaporates out of a lake
Three Characteristics of Braided Rivers - Answer 1.) High-level of sediment
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? - Answer 4 cm/s
Electromagnetic Spectrum - Answer Radio -- Microwave -- Infared -- Visible -- Ultraviolet -- X-ray --
Gamma
Mnemonic Device: Red Martians Invaded Venus Using X-ray Guns
, Coulomb's Law - 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
Acceleration - Answer Change in Velocity divided by Time (D)/(S^2)
A ball is thrown upward. What is the magnitude and resistance direction as the ball rises? - Answer
Magnitude = g (9.8 m/s^2)
Resistance Direction = downward
Newton's Accomplishments - Answer Discover of Gravity
Three Laws of Motion
Newton's Three Laws of Motion - Answer 1.) Inertia - an object at rest will remain at rest and an object
in motion will remain in motion, unless acted upon by an external force
2.) Rate of Change - an object that is influenced by a force moves in relation to the force's magnitude
and direction
3.) Every action has an equal and opposite reaction
Vector vs. Scalar - Answer Vectors have magnitude and direction
Scalars solely have magnitude
