Question

name:__ date: revisiting questions consider indigenous knowledge of inuit hunters and fishers and nasa omg findings to answer the questions below. 1. how might what we have learned help to answer the questions you had at the start of this lesson? 2. what have we figured out that could be used to revise our energy - transfer models? the model below shows how energy is currently moving in earths systems (high co₂, no berm). scenario 1 sun warm water direct contact air (increases in temp, particles move faster) radiation (visible light) glacier (increases in temp, particles move faster and melt) direct contact high co₂ (increases in temp, particles move faster) direct contact land (increases in temp, particles move faster) radiation (visible light) re - radiation (infrared) lesson 8 - 3/3/25 instructions for additional scenarios: show on the model (using words or pictures) how it would change in each scenario, then write a hypothesis in the suggested format for what would happen to polar ice and sea level in this scenario. scenario 2: how might decreased atmospheric co₂ affect polar ice melt below the glacier? (low co₂, no berm) this model is a revision of and addition to your lesson 6 model. hypothesis: if the amount of carbon dioxide in the system decreases, then_ because: scenario 3: how might the berm help slow polar ice melt as atmospheric co₂ causes temperature increases? (high co₂, with berm) this model is a revision of your lesson 5 model. hypothesis: if a berm is built on top of the fjord sill in front of the ilulissat glacier, then___ because:

Explanation:

1. Answer - Explanation Format

1. The knowledge from Inuit hunters, fishers and NASA OMG findings likely provides real - world observations and scientific data. This can help answer initial questions by filling in knowledge gaps, validating or refuting assumptions made at the start. For example, Inuit knowledge might offer long - term local observations about climate changes that can be correlated with scientific data.
2. The figure shows the current energy transfer model with high CO₂ and no berm. We have likely figured out new relationships between factors like CO₂ levels, temperature, and energy transfer between the Sun, air, land, water, and glaciers. This could include understanding how increased CO₂ affects particle movement and energy transfer, which can be used to revise energy transfer models.

For Scenario 2: If the amount of carbon dioxide in the system decreases, then the rate of polar ice melt below the glacier may slow down because lower CO₂ levels are associated with cooler temperatures (less greenhouse effect), which would reduce the energy available to melt the ice.
For Scenario 3: If a berm is built on top of the fjord sill in front of the Ilulissat Glacier, then the rate of polar ice melt may slow down as the berm can act as a physical barrier, reducing the interaction between warm water and the glacier, thus decreasing the energy transfer that causes melting.

Answer:

1. Knowledge from Inuit and NASA can fill knowledge gaps and validate assumptions.
2. New relationships between CO₂, temperature, and energy transfer can be used for model revision.

Scenario 2 Hypothesis: If the amount of carbon dioxide in the system decreases, then the rate of polar ice melt below the glacier may slow down because lower CO₂ levels mean less greenhouse - induced warming.
Scenario 3 Hypothesis: If a berm is built on top of the fjord sill in front of the Ilulissat Glacier, then the rate of polar ice melt may slow down because the berm can reduce warm - water - glacier interaction.
