    Physical weathering

  • 31

    Where does hysical weatheribg occur?

    Physical weathering happens especially in places places where there is little soil and few plants grow, such as mountain regions and hot deserts.

  • 32

    is the process of breaking down of rocks.

    weathering

  • 33

    Water, ice, wind, gravity and changing temperature are agents of

    physical weathering

  • 34

    occurs when water continually seeps into cracks, freezes and expands eventually breaking the rocks apart.

    freeze-thaw

  • 35

    _ happens when rocks surfaces are frequently exposed with water, wind and gravity.

    abrasion

  • 36

    Carbonation occurs when _ dissolves to rainwater producing

    carbon dioxide, weak acid

  • 37

    _ happened when SO, and NO combined with rainwater and produce _ that reacts with rocks.

    acidification, acid rain

  • 38

    is a process of breaking down of rocks by acidic water to produce clay and soluble salts.

    hydrolysis

  • 39

    is a type of chemical weathering where water reacts chemically with the rocks, modifying its _

    hydration, chemical structure

  • 40

    _ animals create holes on the ground and move rock fragments to the surface exposing them to environmental factors of weathering.

    burrowing,

  • 41

    _ and _ produce acidic substance that slowly disinterested

    plants and animals

  • 42

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

    Chemical weathering

  • 43

    chemical addition of water

    hydration

  • 44

    the breakfown of rock by acidic water to produce clay and soluble salts

    hydrolysis

  • 45

    Is the most active agent of erosion in deserts, open fields, and beaches

    wind

  • 46

    constantly erode and shape the shoreline It can carry large amounts of sands, rock particles and shells.

    waves

  • 47

    major agent of erosion

    winds, waves, running water

  • 48

    is a U-shaped body of water that forms when a river finds a different, shorter course.

    Oxbow Lakes

  • 49

    Is a fan shaped deposit of gravel, sand and even smaller pieces of sediments, such as silt formed when stream flow suddenly slows down.

    Alluvial fan

  • 50

    is a landform created by the deposition of sediments carried by a river as the stream flows to a lake or an ocean

    Delta

  • 51

    Is a flat area of land close to a river or stream.

    Flood plain

  • 52

    It stretches from the banks of the river extending toward the outer edges of a valley

    Flood plain

  • 53

    is a general name for processes by which soil, regolith, and rock move downslope under the force of gravity.

    Mass wasting

  • 54

    a naturally wall that blovks the water created by the deposit of large particles so the fertile soil of river or seabased may be used for agriculture
