Spyhill landfill site
400
Name at least two ways of disposing of garbage, and list at least one advantage and one disadvantage of both methods.
Landfilling and burning wastes.
Landfilling involves burying waste in designated areas, which is cheap and easy to manage, but it takes up a lot of space and can pollute soil and water. Burning garbage reduces its volume, which saves space and can produce energy, but it releases harmful gases and is more expensive.
400
Identify and explain one material that is difficult to recycle and why.
One material that is difficult to recycle is Styrofoam. It is hard to recycle because it is lightweight and bulky, making it expensive to transport and process. Additionally, it often contains food or other contaminants, which can make it unusable for recycling and result in it being sent to landfills instead.

Why should corrosive materials be handled carefully?
Corrosive materials can cause serious harm because they can burn skin, eyes, or damage other body tissues if they touch you. They can also damage surfaces, containers, and equipment if not handled properly. Being careful with corrosive materials helps keep people safe and prevents accidents or environmental harm.

How can knowing hazard symbols help you stay safe?
Knowing hazard symbols helps you stay safe by warning you about dangerous materials, like poisons, flammable items, or corrosive chemicals. These symbols show what precautions to take, like wearing gloves, keeping items away from flames, or avoiding skin contact. By understanding these signs, you can handle materials safely and avoid accidents or harm to yourself and others.

Name a personal action you can take to reduce waste at home.
Using reusable bags when doing shopping
Repairing items that are broken
Composting food scraps in the green bin
500
Explain how increased consumption and production of materials can impact the environment and propose two specific actions to reduce these impacts.
Increased consumption and production of materials can harm the environment by depleting natural resources, polluting air and water, and creating large amounts of waste. To reduce these impacts, people can recycle materials like paper, plastic, and metal to keep resources in use and reduce waste. Additionally, choosing reusable items instead of disposable ones helps cut down on the need for constant production and saves resources.

Explain how repairing an item before discarding it can help the environment.
Repairing an item instead of throwing it away helps the environment by reducing waste that ends up in landfills. It also saves natural resources and energy that would have been used to make a new item. By fixing things, we can use them longer and lower the demand for new production, which reduces pollution and helps protect the planet.
500
Explaine the environmental risks of dumping poisonous materials, like pesticides, into the ground.
Dumping poisonous materials like pesticides into the ground can harm plants, animals, and people by contaminating the soil and water. These chemicals can seep into underground water supplies or nearby rivers, making the water unsafe to drink or use. Poisoned soil can also harm plants and kill important insects, disrupting the balance of nature and making the land unhealthy for farming or living.

Explain at least two advantages and two disadvantages of composting.
Advantages of Composting:
Composting reduces waste by turning food scraps and yard waste into nutrient-rich soil, helping plants grow better.
It keeps organic waste out of landfills, which reduces harmful gases like methane that contribute to climate change.
Disadvantages of Composting:
Composting can take time and effort, as it needs regular care, like mixing and keeping the right moisture level.
If not done properly, compost piles can attract pests or create bad smells, especially if meat or oily foods are added.
