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
Answer
Brief Explanations:
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:
- igneous
- metamorphic
- sedimentary
