FAQs on Understanding Climate & Climate Changes Video Lecture - Class 7 Oxford Science: Chapter Notes, Worksheets & Tests
| 1. What is climate change and how does it differ from weather? |  |
Ans. Climate change refers to long-term shifts in temperature, precipitation patterns, and other aspects of the Earth's climate system. It is different from weather, which refers to short-term atmospheric conditions in a specific location. While weather can change daily or hourly, climate change occurs over a much longer time scale and affects larger regions or the entire planet.
| 2. How do greenhouse gases contribute to climate change? | |
Ans. Greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere and contribute to the greenhouse effect. This effect is necessary to keep the planet warm enough to sustain life, but human activities, such as burning fossil fuels and deforestation, have increased the concentration of these gases. This extra buildup of greenhouse gases intensifies the greenhouse effect, leading to global warming and climate change.
| 3. What are the main causes of climate change? | |
Ans. The main causes of climate change are primarily attributed to human activities. These include the burning of fossil fuels (coal, oil, and natural gas), deforestation, industrial processes, and agricultural practices. These activities release large amounts of greenhouse gases into the atmosphere, which trap heat and alter the Earth's climate.
| 4. How does climate change impact ecosystems and biodiversity? | |
Ans. Climate change has significant impacts on ecosystems and biodiversity. Rising temperatures can disrupt the natural balance of ecosystems, affecting the distribution and abundance of plant and animal species. It can lead to shifts in migration patterns, changes in flowering and breeding times, and increased risk of extinction for vulnerable species. Additionally, rising sea levels and extreme weather events can cause habitat loss and destruction, further threatening biodiversity.
| 5. What are the consequences of climate change for human societies? | |
Ans. Climate change has wide-ranging consequences for human societies. It can lead to more frequent and intense extreme weather events like hurricanes, droughts, and floods, which can result in loss of lives, displacement of communities, and damage to infrastructure. Climate change also affects agriculture and food security, as changing rainfall patterns and temperature extremes can disrupt crop production. Additionally, it poses health risks, including increased heat-related illnesses and the spread of diseases.
