Using Figure 1 above or Rock Cycle Interactive website, which answer choice is an INCORRECT statement?
*
1 point
Sedimentary rocks can become metamorphic rocks.
Metamorphic rocks can be broken into sediments that could become sedimentary rocks.
Igneous rocks can become metamorphic rocks when exposed to heat and pressure.
In order for a sedimentary rock to become a metamorphic rock it must be melted to magma first.
Existing sedimentary rocks can be broken into sediments and then become a new sedimentary rock.
The incorrect statement is: "In order for a sedimentary rock to become a metamorphic rock it must be melted to magma first." This statement is false because metamorphism can occur in a solid state, without the rock being fully melted into magma.
In order for a sedimentary rock to become a metamorphic rock it must be melted to magma first.
Well, that statement is incorrect because sedimentary rocks can indeed become metamorphic rocks without being melted into magma. They can undergo changes due to heat and pressure, which can transform them into metamorphic rocks. So, let's just say that statement is a bit melty and not very solid!
The incorrect statement is: "In order for a sedimentary rock to become a metamorphic rock, it must be melted to magma first."
To determine which answer choice is incorrect, we need to analyze each statement and identify any inaccuracies.
Statement 1: Sedimentary rocks can become metamorphic rocks.
This statement is accurate. Sedimentary rocks can undergo metamorphism due to the application of heat and pressure. Therefore, the first statement is correct.
Statement 2: Metamorphic rocks can be broken into sediments that could become sedimentary rocks.
This statement is also correct. Through weathering and erosion processes, metamorphic rocks can be broken down into small particles, or sediments, which can then be transported and deposited to form new sedimentary rocks.
Statement 3: Igneous rocks can become metamorphic rocks when exposed to heat and pressure.
This statement is true. Igneous rocks, whether intrusive or extrusive, can be subjected to high temperatures and pressure, leading to changes in their mineral composition and texture, resulting in the formation of metamorphic rocks.
Statement 4: In order for a sedimentary rock to become a metamorphic rock, it must be melted to magma first.
This statement is inaccurate. Sedimentary rocks can undergo metamorphism without being melted into magma. The application of heat and pressure is sufficient to cause the transformation of sedimentary rocks into metamorphic rocks.
Statement 5: Existing sedimentary rocks can be broken into sediments and then become a new sedimentary rock.
This statement is true. Sedimentary rocks can be eroded, transported, and deposited as sediment. Over time, these sediments can lithify and undergo compaction and cementation processes, resulting in the formation of new sedimentary rocks.
Therefore, the incorrect statement is:
"In order for a sedimentary rock to become a metamorphic rock, it must be melted to magma first."
