    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.
