Landfills use two methods to prevent leachate from contaminating the ground water. What are these methods?

• Liners and leachate collection systems

• Incineration and recycling

• Composting and mulching

• Open dumping and burning

The process used to remove gases that are trapped inside of a landfill is called:

• Gas extraction

• Water filtration

• Soil compaction

• Incineration

'Biodegradable' means:

• Can be broken down by natural processes

• Cannot be broken down by natural processes

• Is made of plastic

• Is always harmful to the environment

'Nonbiodegradable' means:

• Can be broken down by natural processes

• Cannot be broken down by natural processes

• Is always useful to the environment

• Is a type of renewable resource
