Correct answers for connexus 6th grade 2022
1. The major cause of the greenhouse effect is option D - carbon dioxide in the atmosphere.
To get this answer, you need to understand the greenhouse effect. The greenhouse effect is the process by which certain gases, called greenhouse gases, trap heat in the Earth's atmosphere and prevent it from escaping into space. This leads to an increase in the Earth's temperature, known as global warming.
Out of the given options, carbon dioxide (CO2) is the most significant greenhouse gas that contributes to the greenhouse effect. When fossil fuels like coal, oil, and natural gas are burned for energy, they release carbon dioxide into the atmosphere. This increase in CO2 levels enhances the greenhouse effect and leads to global warming.
2. An effect of global warming is option B - rising sea level over a period of time.
To determine this answer, you need to understand the impacts of global warming. Global warming can cause the polar ice caps and glaciers to melt, which contributes to the rise in sea levels. As the temperature rises, ocean water expands, resulting in the flooding of coastal areas. This sea-level rise poses a threat to coastal communities, ecosystems, and infrastructure.
While options A, C, and D might be indirectly related to global warming, rising sea levels are a direct consequence of the Earth's increasing temperature due to global warming.
3. The form of energy that can be connected closely to climate change is option B - coal.
To find this answer, you need to associate energy sources with their impact on climate change. Coal is a fossil fuel that releases a significant amount of carbon dioxide and other greenhouse gases when burned for energy. These emissions contribute to global warming and climate change.
While options A, C, and D can have some environmental impacts, coal has the most significant connection to climate change due to the high carbon emissions associated with its use.
4. The choice that would have the smallest impact on climate change when purchasing apples at the store is option B - buying apples that have no packaging.
To determine this answer, you need to consider the environmental impact of each choice. While all the options might have some positive environmental aspects, buying apples that have no packaging has the smallest impact on climate change.
Options A, C, and D (buying locally grown apples, buying organic apples, and buying in large quantities) can all have environmental benefits, but reducing packaging waste, such as plastic or cardboard, helps to minimize the use of fossil fuels in the production and disposal of packaging materials.
5. The activities ordered from greatest to least impact to reduce consumption of fossil fuels is option C - drive alone to work, drive an electric car to work, carpool to work.
To determine this answer, you need to consider the energy efficiency and environmental impact of each activity.
Driving alone to work has the greatest impact on fossil fuel consumption because it involves solely relying on a non-electric vehicle. This typically leads to higher fuel consumption and emissions.
Driving an electric car to work comes next in the order, as electric vehicles help reduce fossil fuel consumption by running on electricity rather than gasoline or diesel. However, they still require energy for charging, which may come from fossil fuel sources depending on the electricity grid's composition.
Carpooling to work has the least impact on fossil fuel consumption among the options given, as it allows multiple people to share a single vehicle, reducing the number of cars on the road and overall fuel use.
Understanding the impact of transportation choices helps you prioritize options that reduce reliance on fossil fuels and contribute to combating climate change.
1. The major cause of the greenhouse effect is option D, carbon dioxide in the atmosphere.
2. An effect of global warming is option B, rising sea level over a period of time.
3. The form of energy that can be closely connected to climate change is option B, coal.
4. The choice that would have the smallest impact on climate change when purchasing apples at the store is option B, buying apples that have no packaging.
5. The correct order of activities from greatest to least impact to reduce consumption of fossil fuels is option A, walk to work, carpool to work, drive alone to work.
