Fossils |
Read: Earth's Changing Surface "Fossils" (pp. 108-116)
Key Terms: Fossil, Mold, Cast, Petrified Fossil, Trace Fossil, Paleontologist, Scientific Theory, Evolution, Extinction Fossil Index
Homework: Bring in a small object to fossilize (trinket, shell, chicken bone, etc.) Some supplies we may need from home, ask you parents: freezer storage bags of grass cuttings, dried leaves, random very small pieces of organic yard stuff. Copy this chart in your notebook. Animations & Graphics

Relative Age & Radio Acitve Dating |
Read: Earth's Changing Surface "Relative Age of Rocks" (pp. 117-121)
& "Radioactive Dating" (pp. 123-126) Key Terms: Relative Age, Absolute Age, Index Fossil, Radioactive Decay, Half-life, Unconformity Relative Ages
To find the relative age of rocks, do you need to know their exact age? Explain. What is the principle of superposition? Animations & Graphics

Identify the type of unconformity shown. Is it possible that there were originally more layer of rock?
Describe how the rocks on the left of the fault moved in relation to the rocks on right. Hypothesize how the hill of the left side of the figure formed? |
Is it possible to conclude if the igneous intrusion on the left is older or younger than the nonconformity nearest to the surface?
Hypothesize which two layers of rock may have had been much thicker in the past. |
