100
A substance that cannot be separated or broken down into simpler substances by chemical means.
What is an element?
100
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
What is erosion?
100
a type of fossil that forms when sediments fill in the cavity left by a decomposed organism.
What is a cast?
100
the central part of the Earth below the mantle.
What is the core?
100
the bending, tilting, and breaking of the Earth's crust; the change in the shape of rock in response to stress.
What is deformation?
200
a solid whose atoms, ions, or molecules are arranged in a definite pattern.
What is a crystal?
200
a naturally occurring solid mixture of one or more minerals or organic matter.
What is a rock?
200
a fossilized mark that is formed in soft sediment by the movement of an animal.
What is trace fossil?
200
the thin and solid outermost layer of the Earth above the mantle.
What is the crust?
200
the body of molten rock that feeds a volcano.
What is a magma chamber?
300
a substance made up of atoms of two or more different elements joined by chemical bonds.
What is a compound?
300
the process in which material is laid down.
What is deposition?
300
a fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers.
What is index fossil?
300
the layer of rock between the Earth's crust and core.
What is the mantle?
300
the study of earthquakes.
What is seismology?
400
a naturally formed, inorganic solid that has a definite crystalline structure.
What is a mineral?
400
the series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes.
What is rock cycle?
400
the trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock.
What is a fossil?
400
the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
What is lithosphere?
400
a vent or fissure in the Earth's surface through which magma and gases are expelled.
What is a volcano?
500
The way in which a mineral reflects light.
What is luster?
500
the chemical makeup of a rock; describes either the minerals or other materials in the rock.
What is composition
500
a mark or cavity made in a sedimentary surface by a shell or other body.
What is a mold?
500
the strong, lower part of the mantle between the asthenosphere and the outer core.
What is the mesosphere?
500
a wave of energy that travels through the Earth, away from an earthquake in all directions.
What is seismic wave?
