Question

match the following definitions with the correct term.
the record and sequence of events in earths history
determining the specific age of an object
determining the relative order of past events without necessarily determining their exact age
the process by which an unstable atomic nucleus releases energy
a. absolute dating
b. geologic timescale
c. radioactive decay
d. relative dating

Explanation:

• The geologic timescale is a system that organizes the record and sequence of events in Earth's history.
• Absolute dating is used to determine the specific age of an object.
• Relative dating focuses on determining the relative order of past events without necessarily finding their exact age.
• Radioactive decay is the process where an unstable atomic nucleus releases energy.

Answer:

• "the record and sequence of events in Earth's history" → b. geologic timescale
• "determining the specific age of an object" → a. absolute dating
• "determining the relative order of past events without necessarily determining their exact age" → d. relative dating
• "the process by which an unstable atomic nucleus releases energy" → c. radioactive decay
