Assesment Q's for ALL!
100
One of the common minerals that make up most of the rocks of Earth's crust.
What is a rock-forming mineral?
100
Clastic, organic, and chemical.
What are the three major groups of sedimentary rocks?
100
Florida and Hawaii.
What are the only two places in the U.S. that have coral reefs?
100
A series of processes on Earth's surface and in the crust and mantle that slowly change rocks from one kind to another.
What is the rock cycle?
100
Meta: change, morphosis: form.
What does metamorphic mean?
200
A rock that is made up of Quartz, Feldspar, Hornblende, and Mica.
What is Granite?
200
Building and sculpture (like the Lincoln Memorial).
What are the main uses for metamorphic rock?
200
A structure of calcite skeletons built up by coral animals in warm, shallow ocean water.
What is a coral reef?
200
Sedimentary, Metamorphic, and Igneous rocks.
What are the rocks included in the rock cycle?
200
Limestone.
What type of rock is made up of ancient coral?
300
A dark-colored rock that is low in silica.
What is Basalt?
300
Erosion, Deposition, Compaction, and Cementation.
What is the series of processes that form sedimentary rocks?
300
Over thousands of years.
How long does it take for a coral reef to form?
300
Erosion, deposition, heat and pressure, melting, and volcanic activity.
What are the proceses in the rock cycle?
300
Small, solid pieces of material that comes from rocks or living things.
What is sediment?
400
When a rocks grains are large and easy to see.
What is course-grained?
400
Origin, texture, and mineral composition.
What are the three things geologists use to classify igneous rocks?
400
Tiny relatives of jellyfish that eat by catching microscopic creatures that float by with their tentacles.
What are coral animals?
400
Plate movements start the rock cycle by helping to form magma, the source of igneous rocks. They also cause faulting, folding, and other motions of the crust that help to form sedimentary and metamorphic rocks.
What is the role of plate tectonics in the rock cycle?
400
Particles of minerals or other rocks which give a rock it's texture.
What are the grains of a rock?
500
Igneous Rock, Sedimentary Rock, and Metamorphic rock.
What are the three major groups in which geologist classify rocks into?
500
Hard, dense, durable, abrasive.
What are some characteristics that make igneous rocks useful?
500
Coral Reefs would grow upward too.
What would happen to a coral reef if sea level rises above it?
500
Magma, Igneous, Sedimentary, and Metamorphic Rocks.
What are the four steps in the rock cycle?
500
Building materials and tools.
