Question

The picture below shows an incorrect diagram of the rock cycle. an incorrect diagram of the rock cycle. the diagram contains three ovals containing rock types labeled a, b, and c, and six arrows connecting the rock types labeled 1 to 6. a (igneous rocks) in connected to b (metamorphic rocks) by 1 (weathering and erosion) and connected to c (sedimentary rocks) by 5 (heat and pressure). b (metamorphic rocks) is connected to a (igneous rocks) by 2 (melting) and connected to c (sedimentary rocks) by 4 (heat and pressure). c (sedimentary rocks) is connected to b (metamorphic rocks) by 3 (weathering and erosion), and connected to a (igneous rocks) by 6 (melting). how can the flaw in the diagram be corrected? by reversing the direction of arrows 1 and 2 by reversing the direction of arrows 5 and 6 by interchanging the labels inside ovals a and b by interchanging the labels inside ovals b and c

Answer 1

The diagram of the rock cycle should be corrected by interchanging the labels inside ovals B (metamorphic rocks) and C (sedimentary rocks). This change reflects correctly that sedimentary rocks can form from igneous rocks through weathering and erosion, and metamorphic rocks form from both igneous and sedimentary rocks through heat and pressure.

Step-by-step explanation:

The flaw in the rock cycle diagram can be corrected by interchanging the labels inside ovals B and C.

This adjustment accounts for the correct transitions between different rock types in the rock cycle: sedimentary rocks (not metamorphic) form from weathering and erosion (process 1) of igneous rocks.

On the other hand, metamorphic rocks are the result of heat and pressure (process 5) applied to either igneous or sedimentary rocks.

Therefore, by correctly labeling the transitions, igneous rocks become sedimentary through weathering and erosion, and either igneous or sedimentary rocks are transformed into metamorphic rocks under heat and pressure.

The processes of melting and solidification will still convert metamorphic or sedimentary rocks into igneous rocks.
