Alisha thought about what she had learned in class. She wanted to explain the concept of global warming to her grandmother. Help Alisha give her grandmother a clear explanation by completing the following statements.(3 points) 3. Human activities like burning fossil fuels and deforestation cause concentrations of flammable gases in the atmosphere to increase. These chemicals act like a blanket, releasing thermal energy . Examples of these chemicals are carbon dioxide and methane . This causes a phenomenon called global warming , which means global temperatures are increasing . When this happens over a long period of time, it contributes to worldwide climate change .
4. This increase in global temperatures leads to the melting of polar ice caps and glaciers, causing sea levels to rise. This is because as the ice melts, the water from it flows into the oceans, expanding their volume. As a result, coastal areas around the world are at risk of flooding and being submerged by rising sea levels.
5. Furthermore, global warming also disrupts weather patterns, leading to more frequent and severe natural disasters like hurricanes, droughts, and heatwaves. This can have devastating effects on ecosystems, wildlife, and human communities, ultimately threatening the balance of our planet's delicate environment.
6. In order to combat global warming and its harmful effects, it is crucial for individuals, governments, and industries to take action to reduce greenhouse gas emissions and transition to cleaner, renewable energy sources. By working together to address the root causes of global warming, we can protect the Earth's climate and ensure a sustainable future for generations to come.
