SCIENCE: ROCKS AND MINERAL QUICK CHECK
UNIT 4 LESSON 3
ARE ROCKS CONSIDERED VALUABLE NATURAL RESOURCES?
1. NO, ROCKS ARE NOT VALUABLE BECAUSE THEY CONTAIN A LOT OF WASTE.
2. NO, ROCKS ARE NOT VALUABLE BECAUSE THEY ARE NONLIVING SOLIDS.
3. YES, ROCKS ARE VALUABLE BECAUSE THEY ARE USEFUL TO PEOPLE.
4. YES, ROCKS ARE VALUABLE BECAUSE THEY ARE PART OF EARTH'S CRUST.
3. YES, ROCKS ARE VALUABLE BECAUSE THEY ARE USEFUL TO PEOPLE.
The correct answers are:
3. YES, ROCKS ARE VALUABLE BECAUSE THEY ARE USEFUL TO PEOPLE.
4. YES, ROCKS ARE VALUABLE BECAUSE THEY ARE PART OF EARTH'S CRUST.
The correct answer is 3. Yes, rocks are considered valuable because they are useful to people. To arrive at this answer, let's examine the other options:
Option 1 suggests that rocks are not valuable because they contain a lot of waste. However, this is not a valid reason to determine the value of rocks. Some rocks may contain waste materials, but that does not diminish their overall value.
Option 2 states that rocks are not valuable because they are nonliving solids. While it is true that rocks are nonliving solids, this does not necessarily mean they are not valuable. Many nonliving solids like minerals and gemstones have significant value.
Option 4 suggests that rocks are valuable because they are part of the Earth's crust. This statement is partially true - rocks indeed make up a significant portion of the Earth's crust. However, being part of the Earth's crust alone does not necessarily make rocks valuable. The value of rocks comes from their various uses, as mentioned in option 3.
Therefore, the most accurate answer is option 3: Yes, rocks are valuable because they are useful to people. Rocks have numerous practical applications, including construction, manufacturing, and even jewelry-making.
