1. In three to five sentences, describe how the diagram of Earth’s carbon cycle demonstrates the interactions among the biosphere (plants), the lithosphere (ground), the atmosphere (air), and the hydrosphere (water).
2. In one to two sentences, explain how the loss of Arctic sea ice may affect the ocean currents and climate near the Western European coast.
3 sentences in question 1 and 1 sentence in question 2.
Explain for 6th grade.
1. The diagram of Earth's carbon cycle shows how carbon moves between the biosphere, lithosphere, atmosphere, and hydrosphere. Plants in the biosphere take in carbon dioxide from the atmosphere through photosynthesis and release oxygen. Animals in the biosphere consume plants and return carbon dioxide to the atmosphere through respiration. Carbon is also stored in the lithosphere as fossil fuels and minerals, and can be released back into the atmosphere through volcanic activity. Additionally, carbon dioxide can dissolve in water, forming a connection between the atmosphere and the hydrosphere.
2. The loss of Arctic sea ice can disrupt ocean currents and potentially impact the climate near the Western European coast. The melting ice can alter the temperature and salinity of the surrounding water, which can affect the flow of current systems like the Gulf Stream. Since the Gulf Stream helps regulate the climate in Western Europe, any changes could result in shifts in weather patterns and temperatures along the coast.
