The question asks: “Air pockets can form in rapidly cooling magma or lava. In which type of rock would you expect air pockets? Igneous or Sedimentary or Metamorphic”
Step-by-step reasoning:
1. Air pockets form when gas bubbles get trapped as magma or lava cools quickly — like when lava erupts and hardens fast.
2. Rocks that form from cooled magma or lava are called igneous rocks.
3. Sedimentary rocks form from layers of sediment (like sand or mud) being pressed together — no magma involved.
4. Metamorphic rocks form when existing rocks are changed by heat and pressure deep underground — also not from cooling magma/lava.
5. So, air pockets only happen in rocks made from cooling magma or lava → that’s igneous rocks.
Final Answer:
Igneous
