Earth Day Quiz! Test Your Facts And Knowledge! Trivia

Explanation
The refrigerator uses the most energy among the given household appliances. This is because it runs continuously to keep food and beverages cool, maintaining a low temperature inside. The compressor and motor of the refrigerator consume a significant amount of electricity to maintain this cooling process. On the other hand, the toaster, dishwasher, and washing machine are used for shorter periods of time and do not require continuous energy consumption like the refrigerator.

Explanation
The clothes dryer uses the second most amount of energy among the given household appliances. This is because clothes dryers typically consume a significant amount of electricity or natural gas to generate heat and dry the clothes. While a hair dryer may use a lot of energy in a short period of time, the clothes dryer is used for longer durations and therefore consumes more energy overall. The microwave and computer, on the other hand, typically use much less energy compared to a clothes dryer.

Explanation
For every degree above 20C that you set your household thermostat in the winter, the heating costs rise by 5%. This means that if you increase the temperature by one degree above 20C, the heating costs will increase by 5%.

Explanation
A typical shower uses approximately 100 litres of water.

Explanation
The average Canadian uses 36,000 L of water each year for toilet flushing. This is because toilets require a significant amount of water to effectively flush waste down the drain. Given that toilets are used multiple times a day by each individual, the water usage for this purpose adds up quickly over the course of a year.

Explanation
By turning off the tap while brushing teeth or washing face, one can save a significant amount of water. The average amount of water saved by doing so is 11 liters. This is because leaving the tap running while performing these activities can result in a wastage of water, and by turning it off, one can conserve this amount.

Explanation
Composting is a process in which organic waste, such as food scraps and yard trimmings, is broken down by microorganisms into a nutrient-rich soil amendment. By composting, a significant portion of household waste that would otherwise be sent to landfills can be diverted. This reduces the overall volume of waste generated by a household. The correct answer, 50%, suggests that composting can reduce household waste by half, indicating that a substantial amount of waste can be effectively managed through this environmentally friendly practice.

Explanation
On average, a household wastes 14% of their food purchases. This means that out of every 100 units of food purchased, 14 units are wasted. This could be due to various factors such as spoilage, expiration, or simply buying more food than needed. It is important for households to be mindful of their food consumption and try to minimize waste in order to save money and reduce environmental impact.

Explanation
Approximately 50% of the chemicals that are used to protect lawns, gardens, and crops from insects and pests end up in our drinking water. This suggests that a significant portion of these chemicals are not effectively contained or filtered out before reaching our water sources. The presence of these chemicals in our drinking water raises concerns about potential health risks and the need for improved methods of pesticide management and water treatment.

Explanation
Livestock for meat production is the most wasteful type of food production in terms of resources used. This is because raising livestock requires a significant amount of land, water, and feed. The process of producing meat also leads to a higher carbon footprint compared to other food production methods. Additionally, livestock farming contributes to deforestation and water pollution. Therefore, choosing alternative food sources such as plant-based options can help reduce resource waste and environmental impact.

Explanation
One busload of passengers takes the equivalent of 40 cars off the road during a typical rush hour. This means that if all the passengers on the bus were to drive their own cars instead, it would require 40 cars to accommodate them. By taking the bus, these passengers are reducing traffic congestion and the number of cars on the road, resulting in less pollution and a more efficient transportation system.

Explanation
Keeping your tires inflated to the proper pressure can improve gas mileage by about 3.3%. This is because when tires are underinflated, they create more rolling resistance, which requires more energy and fuel to overcome. By maintaining the proper tire pressure, the rolling resistance is minimized, resulting in improved fuel efficiency.

Explanation
The correct answer is 70% because it indicates that a significant amount of waste in landfills has the potential to be recycled. This suggests that there is a large portion of waste that is not being properly managed and could be diverted from landfills through recycling efforts.

Explanation
Aluminum cans take approximately 100 years to decompose. This is because aluminum is a durable material that does not easily break down in the environment. It takes a significant amount of time for natural processes, such as weathering and oxidation, to break down the can into smaller pieces and eventually decompose it completely. Therefore, it is important to recycle aluminum cans to reduce the amount of waste in landfills and minimize the environmental impact.

Explanation
The average family of four people uses around 1000 plastic bags per year. This number is often cited as an estimate for the amount of plastic bags used by a typical family. Plastic bags are commonly used for grocery shopping, storing items, and other purposes, contributing to their high consumption. However, it is important to note that this number can vary depending on individual habits and practices.
