    responsible for shaping the Earth’s surface and forming the geologic features seen on the earth’s surface

    Exogenic Processes

    Weathering

  • 3

    breakdown of rocks at the earth’s surface by the action of water, ice, acids, salts, plants, anomals, gravity, and changing temperatures

    Weathering

  • 4

    Types of Weathering

    Physical Weathering

  • 5

    Caused by the effects of changing temperatures on rocks, causing rocks to break apart

    physical weathering

  • 6

    examples of physical weathering

    swiftly moving water

  • 7

    Types of physical weathering

    Freeze Thaw

  • 8

    Type of physical weathering wherein water continually seeps into cracks, freezes and expands, eventually breaking the rock apart

    Freeze thaw

  • 9

    It can happen as cracks develop parallel to the land surface as a consequence of the reduction in pressure during uplift and erosion. Heat Temperature

    Exfoliation

  • 10

    Caused by rainwater reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts.

    Chemical Weathering

  • 11

    Types of Chemical Weathering

    Carbonation

  • 12

    carbon dioxide in the air dissolves in rainwater and becomes weakly acidic. This weak “carbonic acid” can dissolve limestone as it seeps into cracks and cavities.

    carbonation

  • 13

    the breakdown of rock by acidic water to produce clay and soluble salts. takes place when acid rain reacts with rock-forming minerals such as feldspar to produce clay and salts that are removed in solution.

    Hydrolysis

  • 14

    a type of chemical weathering where water reacts chemically with the rocks, modifying its chemical structure.

    Hydration

  • 15

    the breakdown of rock by oxygen and water, often giving iron- rich rocks a rusty-colored weathered surface.

    Oxidation

  • 16

    Occurs when rocks are weakened by different biological agents like plants and animals. When plant roots grow through rocks, it creates fracture and cracks that result eventually to rock breakage.

    Biological Weathering

  • 17

    Classification of Biological Weathering

    biological weathering by physical means

  • 18

    Burrowing of animals like shrews, moles, and earthworms create holes on the ground by excavation and move the rock fragments to the surface

    Biological Weathering by Physical Means

  • 19

    Breakdown of rocks by oxygen and water often giving iron- rich rocks a rusty-colored weathered surface.

    Biological Weathering by Chemical Compounds

  • 20

    is the process by which soil and rock particles are worn away and moved elsewhere by gravity, or by a moving transport agent – wind, water or ice.

    Erosion

  • 21

    Types of erosion

    Wind erosion

  • 22

    occurs in flat bare areas or dry, sandy and loose soils. It detaches soil particles and transports them by the wind.

    Wind erosion

  • 23

    The moving of glaciers, Change in shape of land, Entire rocks are moved due to an avalanche

    Glacial Erosion

  • 24

    the most common erosion agent. Millions of tons of sediments are picked up and transported everyday along rivers, coasts, and in deep oceans around the world.

    Water Erosion

  • 25

    or a mass movement, is the downslope movement of rock, soil, and ice due to gravity. It is also a natural hazard that can cause damage to life and property.

    Rock Fall

  • 28

  • 29

    the process in which the sediments is dropping in a new place.
