Verified step by step guidance1
Step 1: Understand the fossil record. The fossil record is a collection of preserved remains or traces of organisms from the past, found in sedimentary rock layers. It provides evidence of changes in species over time.
Step 2: Analyze the first statement: 'All organisms have remained unchanged over time.' This is incorrect because the fossil record shows evidence of evolution, adaptation, and changes in species over millions of years.
Step 3: Evaluate the second statement: 'Fossils are only found in igneous rocks.' This is incorrect because fossils are typically found in sedimentary rocks, which form from the accumulation of sediments where organisms are buried and preserved.
Step 4: Consider the third statement: 'Many species that once existed are now extinct.' This is correct because the fossil record shows that many species have disappeared over time, providing evidence of extinction events.
Step 5: Assess the fourth statement: 'The age of Earth is less than 10,000 years.' This is incorrect because scientific evidence, including radiometric dating, indicates that Earth is approximately 4.5 billion years old.
