ES 4 Online Education Roeder- SUMMER 2023 HOMEWORK # 7 –Greenhouse Gases and Rising Sea Level and their impact Please WATCH the videos posted this week, and do some independent research if needed. Answer in DETAIL and in a STRONG PARAGRAPH (5-6 Sentences), the following questions regarding Climate Change, Rising Sea Levels, the Greenhouse Effect and Greenhouse Gases 1) What is the difference between the Greenhouse effect and the ENHANCED Greenhouse effect? How do EACH have an impact of the planet? The Greenhouse effect is a natural process that warms the earth in order to sustain life on earth. The enhanced Greenhouse effect is caused by human activities. Emitting greenhouse gases trap heat in the atmpsphere, causing global warming. The greenhouse effect gradually increases in Earth’s temperature. The enhanced Greenhouse effect causes the planet to warm up faster, leading to more severe climate change. 2) In the video, Rising Sea Levels- Changing Planet , name 3 PHYSICAL IMPACTS of rising sea levels in some of the US' major coastal cities? Rising sea levels can cause significant problems in coastal cities. As the sea level rises, it can lead to more frequent and severe flooding, which can damage buildings, homes, and other infrastructure. Rising sea levels can also lead to the erosion of beaches and other coastal areas, which can ruin ecosystems and wildlife. The sea level rise can cause saltwater intrusion, which can contaminate freshwater sources and can even more environmental damage. Rising sea levels causes severe storm surges, powerful storms are already starting to happen here in the United States. 3) According to the video, Rising Sea Levels- Changing Planet , in DETAIL, explain what TWO events are causing sea levels to rise? A warmer climate that is heating the ocean causing the volume of water to expand, and melting land- based ice sheets and glaciers that are adding to the total amount of water in the oceans. Thermal expansion occurs when the ocean absorbs heat from the atmosphere and warms up. As the water warms, it expands and takes up more space leading to a rise in sea levels. As the Earth’s temperature rises, glaciers and ice sheets melt, and the water flows into the ocean, causing sea levels to rise. 4) According to the video. Rising Sea Levels- Changing Planet , Explain in DETAIL TWO ways that Arctic glaciers are melting? The Arctic is one of the regions most affected by climate change, and rising temperatures are causing glaciers to melt at an alarming rate. In addition to melting from above, caused by warmer temperature, glaciers in the Arctic are also melting from below. This is due to warm ocean water, which is causing the ice to melt faster that it can be replenished by snowfall. As the ice melts, it contributes to rising sea levels. 5) What impacts do Greenhouse gases have on: biodiversity , species habitat , human health , the economy ? Give some DETAILED examples of EACH.
