FAQs on Heat Budget Video Lecture - Geography for UPSC CSE
| 1. What is a heat budget and why is it important for the Earth's climate? |  |
Ans. A heat budget refers to the balance between the incoming and outgoing heat energy in the Earth's atmosphere and surface. It is important because it helps determine the Earth's overall temperature and climate. A positive heat budget can lead to warming, while a negative budget can result in cooling.
| 2. How is the heat budget calculated? | |
Ans. The heat budget is calculated by considering various components, including solar radiation received by the Earth, heat absorbed by the land and oceans, heat lost to space, and heat transferred through processes like convection and conduction. These factors are summed to understand the overall energy balance.
| 3. What factors can disrupt the heat budget? | |
Ans. Factors that can disrupt the heat budget include human activities such as deforestation, pollution, and greenhouse gas emissions, which can increase heat retention in the atmosphere. Natural phenomena like volcanic eruptions and changes in ocean currents can also affect the heat budget.
| 4. How does the heat budget relate to climate change? | |
Ans. The heat budget is directly related to climate change because an imbalance in the heat budget, primarily due to increased greenhouse gases, leads to global warming. This warming can result in significant changes in weather patterns, sea levels, and ecosystems.
| 5. What role do oceans play in the heat budget? | |
Ans. Oceans play a critical role in the heat budget by absorbing, storing, and distributing heat around the planet. They act as a buffer against temperature changes, influencing climate patterns and weather systems. Ocean currents help transport warm water from the equator to the poles, affecting regional climates.
