Ответы
1. **Global Warming**: Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily the emission of greenhouse gases like carbon dioxide (CO2) from burning fossil fuels, deforestation, and other industrial processes.
2. **Greenhouse Effect**: The greenhouse effect is a natural process where certain gases in Earth's atmosphere, such as water vapor, CO2, methane, and nitrous oxide, trap heat from the sun, keeping the planet warm enough to support life. However, human activities are increasing these gases, enhancing this effect and leading to more warming.
3. **Unfavorable Activities**: Activities that negatively change the biosphere's composition include deforestation, burning fossil fuels, industrial farming, and production processes that release large amounts of CO2 and other greenhouse gases into the atmosphere.
4. **Preventing Greenhouse Effect**: To prevent the worsening of the greenhouse effect, we can reduce greenhouse gas emissions by switching to renewable energy sources, improving energy efficiency, reforesting, and adopting sustainable agriculture and transportation practices.
5. **Changing Water Circulation Patterns**: Water circulation patterns are changing due to the warming of the oceans, which affects currents and can lead to altered weather patterns, such as more intense and frequent storms or droughts.
6. **Disappearing Coastal Land**: Rising sea levels, primarily caused by the melting of polar ice and the expansion of warming ocean water, can lead to the disappearance of coastal lands and contribute to the loss of habitats and increased flooding.
7. **Warming Affect on Biological Communities**: Yes, warming affects biological communities by altering habitats, food sources, and the timing of biological events like migration and breeding, which can disrupt ecosystems and lead to species decline or extinction.
8. **Correspondence between Greenhouse Effect and Global Warming**: There is a direct correspondence; the enhanced greenhouse effect, due to increased concentrations of greenhouse gases from human activities, leads to global warming by trapping more heat in the Earth's atmosphere.
