Which Earth material has the highest specific heat? - correct answer Liquid Water (4.18; front
page of ESRT "specific heat of commons materials")
Which of these materials will require the LEAST amount of heat to raise its temperature 5 degrees?
-basalt
-ice
-lead
-granite - correct answer Lead (specific heat = 0.13; front page of ESRT "specific heat of commons
materials")
Which phase change of water requires the ADDITION of the GREATEST amount of heat?
-melting
-freezing
-vaporization
-condensation - correct answer Vaporization (heat energy GAINED = 2260 J/g; front page of ESRT
"properties of Water")
At what temperature is water's density 1.00 g/mL? - correct answer 3.98 degrees Celsius (front
page of ESRT "properties of water")
Lead-206 is the daughter isotope for which radioactive isotope? - correct answer Uranium-238 or
U-238 (front page of ESRT "radioactive decay data")
Which radioactive isotope has a half life of 1,300,000,000 years? - correct answer Potassium-40 or
K-40 (front page of ESRT "radioactive decay data")
A fossil bone contains C-14 and N-14 in the ratio 1:3. How old is the bone? - correct answer 11,400
years old
ratio 1:3 means it's 25% C-14 & 75% N-14
, C-14 went through 2 Half-Lives
2 x 5700 = 11400
(front page of ESRT "radioactive decay data")
What is the percentage by volume of oxygen in Earth's crust? - correct answer 94.04% (front page
of ESRT "average chemical composition of earth's crust, hydrosphere and troposphere")
A stream transports a sand grain 400 cm in 10 seconds. What is the rate at which the sand grain
moved along the stream bed? - correct answer 40 cm/second
Use rate of change formula
400 cm / 10 seconds = 40 cm/s
(front page of ESRT "equations")
Most of the bedrock exposed on the Allegheny Plateau was formed during which geologic time
period? - correct answer Devonian Period
p. 2-3 ESRT - match Allegheny Plateau location on p. 2 with geologic period on p. 3
In which landscape region would the OLDEST bedrock be found? - correct answer Adirondack
Mountains
use p.2-3 for matching locations with bedrock
OLDEST bedrock is at the bottom of the list (use p. 8 to find oldest geologic periods/eras)
Would limestone sedimentary rocks be found near Old Forge? - correct answer No, Old Forge is in
the Adirondack Mountains which has mostly metamorphic rocks
p. 2-3 ESRT - match Adirondack Mountains location on p. 2 with generalized bedrock p. 3
Which landscape region separates the Adirondack Mountains from the Catskills? - correct answer
Hudson-Mohawk Lowlands
p. 2 ESRT
Which landscape region is composed primarily of Cretaceous through Pleistocene weakly
consolidated gravels, sands and clays? - correct answer Atlantic Coastal Plain (Long Island)
p. 2 ESRT
