Question 1
What is the power drawn by a 120-volt microwave
oven that is rated for 15 amps?
A) 0.125 joules
B) 8.0 watts
,C) 1800 watts
D) 135 joules
C) 1800 watts
Rationale: Power is calculated using the formula P =
IV (Power = Current × Voltage). Substituting the
given values: P = 15 A × 120 V = 1800 watts. Option
A uses an incorrect formula (R=V/I gives resistance),
B divides instead of multiplies, and D calculates
energy incorrectly.
Question 2
According to the theory of plate tectonics, the
energy that drives crustal plate movement
originates in:
A) Earthquakes
B) Lithosphere fluidity
C) Seafloor spreading
D) Mantle convection
D) Mantle convection
,Rationale: Mantle convection provides the driving
force for plate tectonics. Heat from Earth's interior
causes convection currents in the mantle, which
drag the overlying tectonic plates. Earthquakes and
seafloor spreading are results, not sources, of plate
movement.
Question 3
The time known as the "coal age" occurred during
which geologic era?
A) Mesozoic
B) Cenozoic
C) Precambrian
D) Paleozoic
D) Paleozoic
Rationale: The "coal age" refers to the
Carboniferous Period, which occurred during the
Paleozoic Era. During this time, vast swamp forests
covered much of the land, and their remains
, eventually formed extensive coal deposits. The
Mesozoic is known as the age of reptiles/dinosaurs,
and the Cenozoic is the age of mammals.
Question 4
Identify the best method of determining the age of
a single rock sample that contains no fossils.
A) Radioactive dating
B) Examination of mineral content
C) Application of the law of superposition
D) Crystal analysis
A) Radioactive dating
Rationale: Radioactive (radiometric) dating
measures the decay of radioactive isotopes within
the rock sample itself, allowing absolute age
determination without requiring fossils. The law of
superposition requires comparing rock layers,
mineral content determines composition not age,
