Negative Impacts
What is a landfill?
A landfill is a site for the disposal of waste materials by burying them.
What does it mean to reduce waste?
To reduce waste means to minimize the amount of waste created, often through careful consumption choices.
What happens if we consume more materials?
If we consume more materials, it leads to increased waste production.
What are solids in waste?
Solids in waste refer to any material that has a definite shape and volume, such as plastic bottles or food scraps.
What is the Particle Model of Matter
The particle model of matter explains that all matter is made up of tiny particles that are in constant motion.
What is burning waste?
Burning waste is the process of incinerating waste to reduce its volume and produce energy.
What is recycling?
Recycling is the process of converting waste materials into new products to prevent waste of resources.
Why is waste production increasing?
What are liquid wastes?
Liquid wastes are substances that are in liquid form, such as wastewater or oil.
How do particles behave in solids?
In solids, particles are tightly packed together and vibrate in place, giving solids a definite shape.
What are two negative impacts of landfills?
Two negative impacts of landfills are soil contamination and the production of greenhouse gases.
What is composting?
Composting is the process of turning organic waste into nutrient-rich soil through decomposition.
How does increased production lead to waste?
Increased production leads to waste because more products being made results in more byproducts and packaging waste.
What is gaseous waste?
Gaseous waste refers to harmful gases released into the atmosphere, such as carbon dioxide or methane.
How do particles behave in liquids?
In liquids, particles are close together but can slide past each other, allowing liquids to take the shape of their container.
Name one environmental issue caused by burning waste.
One environmental issue caused by burning waste is air pollution.
What does it mean to repurpose?
To repurpose means to use an item for a different purpose than it was originally intended for, thereby extending its life.
How can we measure waste production?
We can measure waste production by tracking the amount of waste generated in households or communities over time.
Give an example of solid waste.
An example of solid waste is a discarded piece of furniture or packaging materials.
How do particles behave in gases?
In gases, particles are far apart and move freely in all directions, filling the available space.
How do landfills impact local ecosystems?
Landfills can impact local ecosystems by harming wildlife and contaminating soil and water.
How can repairing items help the environment?
Repairing items helps the environment by keeping them out of landfills and reducing the need for new products.
What is a solution to reduce waste production?
A solution to reduce waste production is to adopt a zero-waste lifestyle that emphasizes reducing, reusing, and recycling.
How can gases be harmful to the environment?
Effect of Heat on particles
The effect of heat on particles is that heating causes them to move faster, increasing the space between them and weakening attractive forces.
