Modeling the Rock Cycle
Students studying the rock cycle made the partial model shown below.
Arrows labeled 1 to 5 are shown in a clockwise direction. Arrow 1 points from a volcano to igneous rock. Arrow 2 points from igneous rock to smaller rock pieces. Arrow 3 points from the smaller rock pieces to sedimentary rock. Arrow 4 points from sedimentary rock to metamorphic rock. Arrow 5 points from metamorphic rock to the volcano.
Multiple Choice Question
Which statement describes the main source of energy that drives the rock cycle?
A.
The rock cycle is driven by thermal energy derived from the Sun and Earth's interior.
B.
The rock cycle is driven by chemical energy derived from Earth's oceans and atmosphere.
C.
The rock cycle is driven by kinetic energy derived from reactions between Earth's elements.
D.
The rock cycle is driven by mechanical energy derived from interactions in Earth's biosphere.
1 answer
The correct answer is:
A. The rock cycle is driven by thermal energy derived from the Sun and Earth's interior.
This statement accurately describes the main sources of energy that drive processes in the rock cycle, such as volcanic activity, weathering, and metamorphism. The Sun provides energy for weathering and erosion, while Earth's interior provides thermal energy that contributes to processes like melting and geothermal activities.
