Metamorphism increases the _____.
a) hardness of rocks
b) coloration of rocks
c) chemical composition of rocks
d) volume of rocks
e) porosity of rocks
Just need to know if my answer or right or wrong. Thanks! :)
a
yes
a) hardness of rocks
To determine if your answer is correct, let's evaluate each option:
a) Hardness of rocks: Metamorphism can indeed increase the hardness of rocks. When rocks undergo metamorphic processes, the minerals within them can recrystallize, forming new mineral structures that are often more compact and have a greater resistance to scratching and abrasion.
b) Coloration of rocks: Metamorphism can sometimes lead to changes in the coloration of rocks due to the formation of new minerals or the rearrangement of existing ones. However, coloration is not a primary characteristic of metamorphism.
c) Chemical composition of rocks: Metamorphism can cause changes in the chemical composition of rocks as existing minerals react with each other under high temperature and pressure conditions. This can result in the formation of new minerals or the alteration of existing ones.
d) Volume of rocks: Metamorphism typically involves the application of intense pressure to rocks, which can cause them to become more dense. As a result, metamorphism generally reduces the volume of rocks rather than increases it.
e) Porosity of rocks: Porosity refers to the amount and size of the openings or spaces between individual particles or grains in rocks. Metamorphism can lead to the compaction of rocks, reducing their porosity.
Based on the information provided, option a) "hardness of rocks" is the most accurate answer. Metamorphism often increases the hardness of rocks through the recrystallization of minerals. Therefore, your answer is correct!
