Sheila is classifying the rocks in her collection. She knows that limestone often contains fossils. In which category of rock should she classify these rocks?

• igneous

• granite

• metamorphic

• sedimentary

Karen’s mom buys a pumice stone at the store. She uses it to smooth rough patches of skin on her feet. She accidentally dropped the pumice in her bath water and was surprised to see the stone float. Why does this kind of rock float?

• It is formed from quartz sands.

• it contains sediment from fish scales.

• It is a rock that has lots of bubbles or air-filled chambers in it.

• it is a metamorphic rock that is very lightweight.

May Ling is examining a piece of limestone with a hand lens. She knows that sedimentary rock has many properties. Which is a property of sedimentary rock?

• It contains no minerals.

• It is made of many layers.

• It is made from magma or cooled lava.

• It is made from the bacteria of live and dead plants.
