Use Table 1 and Figure 2 to describe the difference in atmospheric gases at each site. Explain how the flow of matter and energy differs in these two locations as a result of the concentration difference. Use evidence from any of the tables or figures to support your answer
The concentration of gases in the atmosphere available to the Spruce trees depends in the number of trees in each location.
How do the amount of trees in an area affect concentration of atmospheric gases?The atmosphere contains a mixture of gases such as carbon dioxide, water vapor, oxygen and nitrogen.
Plant such as trees are known to contribute to the amount of gases present in the atmosphere.
Trees remove carbon dioxide from the atmosphere and release oxygen into the atmosphere.
Therefore, the concentration of gases available tongue Spruce trees depends in the number of trees in each location.

The weathering that most likely played the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
What is the weathering process?Rock cliffs can be formed by a variety of weathering processes. One common process is erosion caused by the movement of water as seen here as water flows through the mountains. Over time, these agents of erosion can wear away the softer layers of rock, leaving behind the harder layers that form the cliffs. Physical weathering is caused by the action of natural forces such as water, wind, etc. For example, water can flow into cracks in rock and then freeze and expand when the temperature drops, causing the rock to break apart. Wind can also erode rock surfaces over time by carrying small particles of sand and other debris that scrape and wear down the rock.
Hence, here the largest role in creating the cliff was when water in the river broke down the rocks into smaller pieces, which is present in Option B.
