Climate Change
| Question | Answer |
|---|---|
| How do scientists differentiate between climate and weather for a given area? | They measure of time used to observe atmospheric conditions in a specific area. |
| What factors about the physical orientation of the Earth influence climate? | Natural forces like the ocean, sun and human activities. |
| What is the definition of "Population" | Organisms of the same species living in a particular area. |
| What is the definition of "Species"? | All of the populations of organisms that are similar in appearance and have the ability to interbreed. |
| What is the definition of "Community"? | Populations of different species interacting in a given area. |
| What is the definition of "Ecosystem"? | Interaction of a community and the physical environment (such as climate). |
| What is "Biosphere" defined as? | The sum of the regions of the Earth (water, surface, atmosphere) where living organisms are found. |
| What types of weather events related to climate change do scientists have the strongest evidence to support? | Hurricanes, Droughts, Heatwaves, and Flooding. |
| What Are Greenhouse Gases? | Gases that retain heat in the lower atmosphere, causing the greenhouse effect. |
| What is the relationship between greenhouse gases and energy? | Producing energy releases these gasses and those gases turn into trap heat. |
| What are the Earth's greenhouse gases? | Water Vapor, Carbon Dioxide, Methane, and Nitrous Oxide. |
| What processes naturally add and utilize carbon dioxide to the atmosphere? | Respiration and Decomposition. |
| Why are methane levels of such a concern related to the greenhouse effect? | They remain in the area for years and a very long time. |
| Identify the primary sources of methane. | Fossil fuels, Animals, and Waste (Man made and Natural). |
| What is the source of Water Vapor? | Natural processes associated with the water cycle. |
| What is the source of Nitrous Oxides? | Agricultural practices such as the use of fertilizers and the burning of fossil fuels. |
| What i the source of Ozone? | Natural processes and the interaction of solar energy with pollutants in the lower atmosphere. |
| What is the source of Chlorofluorocarbons (CFCs)? | Compounds used in refrigerants and to make spray propellants. |
| What is some of the current evidence that the climate is changing? | Glaciers and Snow Caps melting. |
| In what ways does increased carbon dioxide affect ocean water and then marine organisms? | It gets rid of the carbonic acid which they use to create shells and sea levels rise. |
| Explain how the properties of water are linked to climate change and weather. | High heat absorption and thermal expansion, creates heat sinks. |
| Can you describe how glaciers have changed since the 1970s globally? | They have been decreasing due to the heat in those areas. |
| How are sea levels related to global ice melt? | Ice melts are the primary reason for the rising sea levels. |
| How does an increase in both the number and severity of extreme weather events connected to climate change? | A warmer atmosphere and warmer oceans load the global weather system with extra energy and moisture. |
| How is carbon linked to all life? | Basic building block and helps form all organisms. |
| How is the structure of carbon related to its characteristics? | Directly determines the unique chemical versatility, bonding geometry, and macroscopic material characteristics. |
| What type of bonds does carbon form to build organic molecules? | Covalent bonds. |
| In what ways is carbon used and essential to living organisms? | Is the backbone of creating and helps form proteins, carbohydrates, lipids, dna and RNA. |
| What processes can remove carbon from the atmosphere and put it back into the biotic portion of the ecosystem? | Photosynthesis. |
| Can you identify what natural and man-made processes add carbon to the atmosphere? | Decomposition, Respiration, Volcanoes, Ocean, Wildfires. |
| How do reservoirs trap the carbon molecule and what human activities release it at accelerated rates? | Natural carbon reservoirs trap carbon through biological, chemical, and physical processes, while human activities accelerate its release primarily through burning fossil fuels and deforestation. |
| Define "Photosynthesis". | The process where plants, algae, and some bacteria turn sunlight, water, and carbon dioxide into food and oxygen. |
| Where do plants exchange gases and capture sunlight? | Stomata. |
| Can you give a description of the organelle responsible for photosynthesis? | The Chloroplast . |
| What are the key structures related to Photosynthesis? | Thylakoids, Grana, Stroma, and Chlorophyll. |
| Can you briefly describe the function of the light reactions and Calvin cycle in photosynthesis? | Otosynthesis converts light energy into chemical energy through light-dependent reactions, which produce ATP and NADPH, and the Calvin cycle, which uses these molecules to fix carbon dioxide into glucose. |
| How is light energy trapped by photosynthesis for use by living organisms? | The energy is trapped by chlorophyll in chloroplasts, converted into ATP and NADPH, and then stored in the chemical bonds of sugars produced in the Calvin cycle. |
| What is a "Carbon Footprint"? | A carbon footprint is the total amount of greenhouse gases, especially carbon dioxide, produced by a person, group, activity, or organization. |
| How is a person's or group’s Carbon Footprint determined? | It is determined by measuring emissions from activities such as transportation, electricity use, heating, food choices, and consumption of goods. |
| What can a Carbon Footprint score reveal? | It can show how much greenhouse gas a person or group contributes to climate change and which activities produce the most emissions. |
| When desertification occurs what are some of the underlying factors and results? | It can result from drought, climate change, deforestation, overgrazing, and poor farming practices. It can lead to loss of fertile soil, reduced vegetation, food shortages, and loss of habitats. |
| Why are such significant changes occurring to coral reefs worldwide? What factors are contributing to these rapid changes and losses? | They're being affected by warmer ocean temperatures, ocean acidification, pollution, and other human impacts. Warmer water can cause coral bleaching, which can damage or kill coral. |
| How does climate change affect communities of organisms? | Climate change disrupts communities of organisms by altering species distributions, biodiversity, community structures, and ecosystem dynamics, often forcing adaptation, migration, or extinction. |
| Why are invasive species sometimes so successful upon introduction | This is because they combine rapid reproduction, broad environmental tolerance, competitive advantages, and the absence of natural enemies in new ecosystems. |
| What are some of the underlying problems with prolonged drought and increased heat waves? | Over Heating, Health Issues, Water Scarcity, Air Quality, etc. |
| What is a vector in terms of disease and how are they impacted by climate change? | Any living organism, moften an arthropod like a mosquito, tick, or flea, that can carry and transmit a pathogen (virus, parasite, or bacterium) from one host to another. |
| How does climate change affect individuals and species? | Climate change affects both humans and wildlife by altering habitats, increasing health risks, and threatening species survival and ecosystem stability. |
| Why is the Calvin cycle said to be independent of light? | Because its chemical reactions do not directly require photons, although it relies on ATP and NADPH produced by light-dependent reactions to proceed. |
