Study Notes
Continental Drift and Plate Tectonics
- In 1910, Alfred Wegener hypothesized that Earth once consisted of a supercontinent surrounded by water, which he named Pangaea.
- The concept of Pangaea supports the idea of continental drift.
Fossil Formation
- Fossils are formed when an organism is quickly buried by sediment, becomes trapped in tree resin or sap, or remains are slowly replaced by mineral crystals.
- Fossils are not formed when an organism is exposed to decomposers and scavengers.
Fossil Analysis
- Paleontologists use a combination of fossil evidence, knowledge of modern animal anatomy, and imagination to develop an idea of what ancient organisms would have looked like.
- When creating a 3-dimensional model of a fossil, paleontologists would use their imagination to determine the method of locomotion of the ancient organism.
Rock Types
- Igneous rocks form from hot, molten rock.
- Sedimentary rocks can contain fossils.
- Metamorphic rocks require pressure to be formed.
Rock Composition
- Minerals are classified as pure substances.
- Rocks are classified as mixtures.
- The chocolate chips in a chocolate chip cookie represent minerals, which are classified as pure substances.
Tectonic Plates
- The collision of the Indian plate and Eurasian plate most likely resulted in the formation of the Himalayas mountain range.
- Fold and fault mountains occur because of heat and pressure, which softens the rock, allowing it to bend without breaking.
- The anticline is found at location B in the fold and fault mountain.
