Useful metals are often chemically combined with other substances forming ____________.

1. ores
2. slags
3. minerals
4. rocks

A ___________ is a rock that contains enough of the metal to make it worthwhile extracting.

1. common ore
2. minerals
3. limestone
4. metal ore

Metals can be extracted from their ores through processes. Which is NOT a method of extraction? ,

1. electrolysis
2. blast furnace
3. electroplating
4. reacting with more reactive material

In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a __________ process since oxygen is being removed.

1. oxidation
2. exothermic
3. reduction

😁 - I can do this! I am ready to try something new.
😅 - I am getting there! I need a bit of help. I am a bit unsure. I might need to practice.
😬 - I need help! I don't understand this. I am not ready to move on yet.
