Geology Unit 3 Vocab Practice

What is the Law of Superposition?

• The layers are all of the same age

• The oldest layers are on top and the youngest layers are on the bottom

• The layers are randomly arranged

• The youngest layers are on top and the oldest layer is on the bottom

What is geology?

• The study of outer space

• The study of the Earth's physical make-up and processes

• The study of human history

• The study of plant life

What is relative dating?

• The process of breaking down rock at the Earth's surface

• The study of how sedimentary rock layers form and their relationships

• Placing a specific number of years on an event, organism, natural sample, artifact by radiometric dating techniques

• Placing events or organisms in chronological order based on their position in the geologic record

What is absolute dating?

• The process of breaking down rock at the Earth's surface

• The study of how sedimentary rock layers form and their relationships

• Placing a specific number of years on an event, organism, natural sample, artifact by radiometric dating techniques

• Placing events or organisms in chronological order based on their position in the geologic record

What is an isotope?

• The remains or impression of remains of a living organism preserved or petrified as rock

• A radioactive form of an element with the same number of protons but different numbers of neutrons

• A type of rock that forms from the cooling of molten rock at or below the surface

• Microscopic mineral grains formed by chemical weathering of rocks

What is a fossil?

• Microscopic mineral grains formed by chemical weathering of rocks

• A type of rock that forms from the cooling of molten rock at or below the surface

• A radioactive form of an element with the same number of protons but different numbers of neutrons

• The remains or impression of remains of a living organism preserved or petrified as rock

What is the rock cycle?

• The study of outer space

• An orderly classification system that gives the order in which geological processes, major events and life forms have happened on the Earth

• The process of breaking down rock at the Earth's surface

• An illustration of how three major rock categories are related to one another

What is the hydrologic cycle?

• An illustration of the relationships between condensation, evaporation and precipitation on the earth and earth's surface

• The study of outer space

• An orderly classification system that gives the order in which geological processes, major events and life forms have happened on the Earth

• The process of breaking down rock at the Earth's surface

What is weathering?

• The process of breaking down rock at the Earth's surface

• The study of outer space

• An orderly classification system that gives the order in which geological processes, major events and life forms have happened on the Earth

• An illustration of the relationships between condensation, evaporation and precipitation on the earth and earth's surface

What is an igneous rock?

• A type of rock that forms from the cooling of molten rock at or below the surface

• Microscopic mineral grains formed by chemical weathering of rocks

• A molten mixture of rock-forming substances, gases, and water from the mantle

• The remains or impression of remains of a living organism preserved or petrified as rock
