    Geological Processes that takes place below the Earth's surface.

    Endogenic

  • 2

    Processes takes place on Earth's surface.

    Exogenic

  • 3

    Sources of Earth's Heat

    1. Compression of matter 2. Sinking of heavier metals into earth 3. Residual heat 4. Radioactive decay within earth's core

  • 4

    Formation of Magma

    Formation of Magma Melting by Decompression Melting due to Addition of Volatiles Melting due to Heat-Transfer from Rising Magma

  • 5

    are solid materials consisting of one or more minerals. They form the Earth's outer layer, known as the crust.

    Rocks

  • 6

    THREE TYPES OF ROCKS

    IGNEOUS SEDIMENTARY METAMORPHIC

  • 7

    EXAMPLES OF IGNEOUS ROCKS?

    Basalt Peridotite Rhyolite

  • 8

    TYPES OF IGNEOUS ROCKS?

    INTRUSIVE IGNEOUS ROCKS EXTRUSIVE IGNEOUS ROCKS

  • 9

    • If magma solidifies underground

    INTRUSIVE IGNEOUS ROCKS

  • 10

    • Magma erupts at the earth's surface and solidifies upon contact with atmosphere or ocean

    EXTRUSIVE IGNEOUS ROCKS

  • 11

    rocks formed from fragments of other rocks. riverbed in loose layers known as sediment. Over millions of years,

    Sedimentary

  • 12

    Refers to the processes that break up and corrode solid rocks, transforming them into sediments

    WEATHERING

  • 13

    TYPES OF WEATHERING?

    1. Physical Weathering 2. Chemical Weathering

  • 14

    • Also called as mechanical weathering • Breaks large masses of rocks into smaller grains or chunks. • pieces are called detritus

    PHYSICAL WEATHERING

  • 15

    Processes of Physical Weathering

    Jointing Frost wedging Root wedging Thermal expansion Salt wedging Animal attack

  • 16

    Rocks have naturally formed cracks in its structure called joints. When rock changes shape due to an increase in pressure,

    Jointing

  • 17

    When water trapped in the joints of rocks freezes, it forces the joints to open, causing it to enlarge and eventually for the rock to break apart.

    Frost wedging

  • 18

    Tree roots can grow into joints and force them to open.

    Root wedging

  • 19

    all matter expands when subjected to intense heat. Forest fires can be of such intensity that it causes rocks to expand.

    Thermal expansion

  • 20

    In arid regions, dissolved salt in groundwater crystallizes and enlarges in open spaces in rocks.

    Salt wedging

  • 21

    Burrowing animals, such as earthworms, grasshoppers, etc., push open cracks, and break rocks into fragments.

    Animal attack

  • 22

    • Chemical reactions that change or destroy minerals when rocks are exposed to water or air. • Temperature and air speeds up the chemical reactions, takes place faster in warm and wet conditions.

    CHEMICAL WEATHERING

  • 23

    dissolution of these minerals breaks rocks apart.

    Dissolution

  • 24

    minerals react with water. This reaction is decomposition

    Hydrolysis

  • 25

    reactions take place when elements combine with oxygen. Rusting is an example of oxidation.

    Oxidation

  • 26

    occurs when minerals contained in rocks absorb water causing the minerals to expand,

    Hydration

  • 27

    In arid regions, dissolved salt in groundwater crystallizes and enlarges in open spaces in rocks.

    Chemical weathering from organisms

  • 28

    • A type of chemical weathering • Breaks bedrock into smaller fragments. and decomposes into clay and sand

    EROSION

  • 29

    • Turbulent action, removes loose and fine-grained materials • Abrasion, wears down surfaces by sandblasting them with windborne particles.

    WIND EROSION

  • 30

    Earth's surface run-off through the action of rivers and streams on rocks, soils, and sediments.

    WATER EROSION

  • 31

    • Waves and currents from large bodies of water, seas and lakes, act on rocks and sediments through pounding and abrasion

    COASTAL EROSION

  • 32

    EXAMPLES OF SEDIMENTARY ROCKS

    Shale Siltstone Flint

  • 33

    is formed when pre existing sedimentary or igneous rock undergoes significant heat and pressure deep within the Earth's crust. Rock into completly new form.

    Metamorphic rock

  • 34

    EXAMPLES OF METAMORPHIC ROCKS

    Phyllite Slate Novaculite
