Relative and Absolute Age

What is the difference between relative age and absolute age in geology?

• Relative age determines the sequence of events, while absolute age provides a numerical age.

• Relative age provides a numerical age, while absolute age determines the sequence of events.

• Both relative and absolute age provide numerical ages.

• Both relative and absolute age determine the sequence of events.

Which method involves determining the age of a fossil by comparing its placement with that of fossils in other layers of rock?

• Relative dating
• Radiometric dating
• Stratigraphic correlation
• Carbon dating

What are the two ways geologists express the age of a rock?

• Geological mapping and mineral analysis
• Sedimentary and igneous classification
• Relative dating and absolute dating
• Fossil dating and radiometric dating

Define Relative Age in geology.

• Relative age is a geological age of a rock or fossil in relation to other rocks or fossils, rather than in terms of absolute age.

• Relative age is the exact number of years since a rock or fossil was formed.

• Relative age is determined by the chemical composition of a rock or fossil.

• Relative age is the age of a rock or fossil based on its color and texture.

Define Absolute Age in geology.

• Absolute age in geology refers to the age of a rock, fossil, or geological event in years and provides a specific time frame for when an object was formed or an event occurred.

• Absolute age in geology is the estimated age of a rock or fossil based on its position in the Earth's strata.

• Absolute age in geology is the age of a rock or fossil determined by the type of minerals it contains.

• Absolute age in geology is the age of a rock or fossil determined by the color and texture of its surface.

What type of rock are fossils most often found in?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Volcanic rock

What does the Law of Superposition state about the layers of rock?

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

• All layers are of the same age.

• The age of layers cannot be determined.

What is an extrusion in geology?

• A type of sedimentary rock

• Lava that hardens on the surface and forms igneous rock

• Magma that hardens under the surface of the Earth in rock layers.

• A fault line
