Definition
| A weak acid (H2CO3) that forms from the reaction of water and carbon dioxide. Most rain water is a very weak carbonic acid solution formed by the reaction of rain with small amounts of carbon dioxide in the atmosphere. |

Definition
| Erosion is the carrying away or displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms |

Definition
| Hydrolysis is a chemical reaction during which one or more water molecules are split into hydrogen and hydroxide ions which may go on to participate in further reactions. |

Definition
| As one of the many kinds of mechanical weathering, ice wedging is the most common. Water fills up cracks in rock, and when it freezes, it expands and cracks the rock, similar to driving an axe into wood. |

| A landslide is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments |

|
Definition
| The process of breaking rocks down into smaller pieces by water continually freezing and thawing, similar to chopping an axe into wood. |

Definition
| It is a rapid movement of a large mass of mud formed from loose earth and water. |

Definition
| Parent material, in soil science, means the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. |
|

Definition
| Soil is the naturally occurring, unconsolidated or loose covering on the Earth's surface |
|

Definition
| Topsoil is the upper, outermost layer of soil, usually the top 2 to 8 inches |
|
|
Term
|
Definition
| Soil not formed from the local rock but from parent material brought in from some other region and deposited, usually by running water, wind, or glacial ice |
