Question

the diagram shows an incomplete rock cycle. which rock types belong in circles 1, 2, and 3? choose the correct answer. 1. igneous 2. metamorphic 3. sedimentary; 1. metamorphic 2. igneous 3. sedimentary; 1. sedimentary 2. igneous 3. metamorphic

Explanation:

To determine the rock types in the rock cycle diagram:

• Circle 1: Igneous rocks form from cooling magma/lava. They can undergo heat and pressure (metamorphism) or melting.
• Circle 2: Metamorphic rocks form from existing rocks (igneous, sedimentary, or other metamorphic) under heat and pressure. They can melt or be weathered/eroded.
• Circle 3: Sedimentary rocks form from weathered/eroded materials (sediments) that compact/cement. They can undergo heat/pressure (metamorphism) or be weathered again.

The first option matches: 1. igneous, 2. metamorphic, 3. sedimentary.

Answer:

1. igneous
2. metamorphic
3. sedimentary
