Text 1
Many planetary scientists argue that the chaotic terrain on Jupiter's moon Europa, characterized by disrupted blocks of ice, suggests a thin ice shell (under 5 kilometers thick) that regularly breaches. This thin-shell model implies that Europa's subsurface ocean frequently interacts with the surface, allowing photosynthetic organisms to potentially thrive near fractures where sunlight penetrates, and facilitating the detection of oceanic biosignatures by passing spacecraft.

Text 2
Conversely, planetary geophysicist Dr. Clara Sterling and her team utilize thermal modeling to argue that Europa's ice shell is likely over 20 kilometers thick. Sterling contends that the heat generated by tidal flexing is dissipated primarily through solid-state convection within the ice, rather than melting it thin. According to Sterling, any chaotic terrain is the result of warm, buoyant ice plumes rising slowly through the thick shell, never actually exposing the ocean directly to the surface.

Based on the passages, is the following statement true or false?
Dr. Clara Sterling would argue that the chaotic terrain on Europa can be explained by geological processes that do not involve the subsurface ocean breaching the ice shell.

Cevap: Cevap

Cevap

True
The correct answer is True because Text 2 presents Dr. Clara Sterling's model, which attributes Europa's chaotic terrain to warm, buoyant ice plumes rising through a thick shell via solid-state convection. She explicitly states that this process does not expose the subsurface ocean directly to the surface, which confirms that she believes the terrain can be explained without the ocean breaching the ice shell.

Adım Adım Çözüm

1
Analyze the claim in Text 1 regarding Europa's chaotic terrain.
Text 1 states that planetary scientists view the chaotic terrain as evidence of a thin ice shell that regularly breaches, allowing the subsurface ocean to interact directly with the surface.
Understanding the baseline assumption that Text 2 will address.
2
Analyze Dr. Clara Sterling's counter-argument in Text 2.
Text 2 states that Sterling proposes a thick ice shell (>20 km) where heat is dissipated by solid-state convection. She argues that chaotic terrain is caused by rising plumes of warm ice that do not expose the ocean to the surface.
Identifying Sterling's specific explanation for the chaotic terrain.
3
Synthesize the two perspectives to evaluate the statement.
The statement asserts that Sterling would argue chaotic terrain can be explained by geological processes that do not involve the ocean breaching the shell. Since Sterling attributes the terrain to solid-state convection and rising ice plumes that never expose the ocean, she indeed argues that these non-breaching geological processes explain the terrain. Thus, the statement is true.
Drawing the logical connection between the two texts to determine the statement's validity.
