Minerals – Earth’s Jewels
Igneous and Sedimentary Rocks
Metamorphic Rocks and the Rock Cycle
Explain how sediment becomes sedimentary rock.
Sediment is pieces of broken rock, shells, mineral grains, and other materials that are deposited deep in the ocean, where it piles up over time. As more layers of sediment pile up, the layers underneath are compacted. Water flows through the sediment and acts like glue. It is the compacted layers that eventually become sedimentary rock.
Which changes metamorphic rock into sediment?
A. compaction and cementation
B. heat and pressure
D. weathering and erosion
The answer is D. Over time, weathering and erosion change metamorphic rock back into sediment.
List the different properties that are used to identify minerals.
Crystal, cleavage and fracture, color, streak and luster, hardness, and specific gravity are used to identify minerals.
Rank the four minerals from softest to hardest.
The correct order is: talc, gypsum, fluorite, and quartz.
Explain why intrusive igneous rocks have large, visible crystals.
Intrusive igneous rocks are formed by magma that is forced upward toward Earth’s surface, but never reaches it. The hot magma sits under the surface and cools very slowly. The cooling is so slow that the minerals in magma have time to form large crystals.
When a mineral splits into pieces with smooth, regular planes, it is said to have _______.
D. specific gravity
The answer is A. Cleavage is a way that rock can break. When rocks break with smooth, regular planes, they have cleavage. Rocks that break into pieces with jagged, rough edges, fracture.
What type of rock is formed after a geyser erupts?
A. chemical rocks
B. detrital rocks
C. organic rocks
D. volcanic rocks
The answer is A. When a geyser erupts, mineral-rich water evaporates. The minerals are left behind and they eventually form chemical rocks.
Where do extrusive igneous rocks form?
A. Earth’s surface
B. inside Earth
The answer is A. Extrusive igneous rocks form when melted rock material cools on Earth’s surface.
Which is most abundant in Earth’s crust?
The answer is B. Feldspar is a type of silicate mineral.
Which is a mineral sold for profit?
The correct answer is D. A mineral that contains a useful substance that can be sold for profit is called an ore.
