Rocks and Minerals Review

Elizabeth is studying some rocks. One of the rocks has imprints of shells on it. Which type of rock does she MOST LIKELY have?

• Igneous

• Metamorphic

• Sedimentary

• Volcanic

Jacob is observing a metamorphic rock that splits into flat pieces, that forms slate. What natural forces within the Earth cause the formation of slate?

• Molten magma deep inside the Earth cools and slowly hardens over time.

• Heat and pressure cause the minerals to be deeply buried and squeezed into a more dense form.

• Lava erupts and runs down the side of a volcano, then cools and hardens.

• Sediments of once living things are deposited over time and become cemented.

Abigail has a rock in her collection that is very smooth and glassy. She knows that the rock was formed by lava that cooled very quickly after a volcanic eruption. Which kind of rock does Abigail have?

• Concrete

• Igneous

• Metamorphic

• Sedimentary

Jack is writing observations of different samples in his mineral collection. Which of the following terms can BOTH be used to describe luster?

• Hard and coarse

• Metallic and soft

• Grainy and rough

• Glassy and metallic

Which of these is NOT a physical property used to identify a mineral?

• weight

• hardness

• color

Mr. Smith's science class is making a chart of different kinds of rocks. Which types of rocks were MOST LIKELY formed deep within the Earth?

• Basalt

• Pumice

• Sandstone

• Marble

Jamie drew a poster for a science project. How can the students in Jamie’s class tell that the shale rock shown is a type of sedimentary rock?

• It was formed from layers of molten magma below the rock layers.

• There are pieces of fossils and shells in the layers of rock.

• The fossils in the rock show that the rock is igneous, not sedimentary.

• The shale was formed from heat and pressure from the surrounding rock.

Christina is testing some mineral properties to help her identify each mineral. For one test, she scrapes a mineral on a special plate to observe the color left behind. Which mineral properties is she MOST LIKELY using this test for?

• Cleavage

• Texture

• Luster

• Streak color

James is conducting several tests on minerals to help identify them. He uses a small hammer to break the mineral. Which property of the mineral might James be testing?

• Cleavage

• Texture

• Luster

• Streak color

Limestone is made up of many layers. Conglomerate is made up of small pebbles. Pumice is full of air pockets. Coquina is made up of tiny pieces of shells. Which of these rocks would be considered an igneous rock?

• Conglomerate

• Coquina

• Limestone

• Pumice
