Zorluk: KolayIdentifying Points of Agreement

Two students discuss the source of heat that warms a deep-sea hydrothermal vent ecosystem.

Student 1
The ecosystem is warmed solely by geothermal energy from Earth's mantle, which heats the seawater as it circulates through subterranean crustal cracks. The sun has no role in warming this environment because solar radiation does not penetrate to these extreme ocean depths.

Student 2
The ecosystem's primary heat source is geothermal energy rising from Earth's mantle. However, minor warming also occurs due to warm, downwelling surface ocean currents that were originally heated by solar radiation.

Based on the descriptions of the two viewpoints, both students agree with which of the following statements?

  1. A
    Solar radiation has no impact on any water that reaches the ecosystem.
  2. Geothermal energy from Earth's mantle contributes to the warmth of the ecosystem.Cevap
  3. C
    Warm downwelling ocean currents are a source of heat for the ecosystem.
  4. D
    Geothermal energy is the sole source of heat that warms the ecosystem.

Cevap

Geothermal energy from Earth's mantle contributes to the warmth of the ecosystem.
Both students agree that geothermal energy from Earth's mantle contributes to warming the ecosystem. Student 1 states that the ecosystem is warmed solely by geothermal energy, while Student 2 states that geothermal energy is the primary heat source. Therefore, both agree on its contribution.

Adım Adım Çözüm

1
Analyze Student 1's position on the heat sources for the ecosystem.
Student 1 believes the ecosystem is warmed solely by geothermal energy.
To identify what Student 1 claims is warming the ecosystem.
2
Analyze Student 2's position on the heat sources for the ecosystem.
Student 2 believes the primary heat source is geothermal energy, but solar-heated downwelling currents also contribute.
To identify what Student 2 claims is warming the ecosystem.
3
Compare both positions to find the common claim.
Both students claim that geothermal energy warms the ecosystem, making it a point of agreement.
To determine the shared belief between both viewpoints.
