Fossils and ancient life quiz for Grade 6 with answers

📚 Quick Study Guide

• 🦴 Fossils: Remains or traces of ancient organisms preserved in rocks.
• 🌱 Types of Fossils: Include body fossils (bones, shells) and trace fossils (footprints, burrows).
• ⏳ Fossil Formation: Occurs through processes like permineralization, where minerals replace organic material.
• 🌍 Paleontology: The study of fossils to understand prehistoric life and environments.
• 📅 Relative Dating: Determining the age of fossils based on their position in rock layers (older layers are usually deeper).
• 🧪 Radiometric Dating: Using radioactive isotopes to determine the absolute age of fossils (e.g., carbon-14 dating).
• 🦕 Index Fossils: Fossils of organisms that lived for a short period and were widespread, used to date rock layers.
