Question

which of the following is true about recycling glass and aluminum?
energy is created in the recycling process.
recycled glass and aluminum always have different properties from the original materials.
recycling glass and aluminum reduces the amount of resources taken from the earth.
it takes more energy to recycle aluminum than to extract it from the ground.

Explanation:

• According to the law of conservation of energy, energy cannot be created or destroyed, only transformed. So the statement "Energy is created in the recycling process" is false.
• Recycled glass and aluminum can have similar properties to the original materials under proper recycling processes. So "Recycled glass and aluminum always have different properties from the original materials" is false.
• Recycling reduces the need to extract new raw materials from the Earth. So "Recycling glass and aluminum reduces the amount of resources taken from the Earth" is true.
• Recycling aluminum actually takes less energy than extracting it from the ground (bauxite). So "It takes more energy to recycle aluminum than to extract it from the ground" is false.

Answer:

Recycling glass and aluminum reduces the amount of resources taken from the Earth.
