Erosion:the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.

  • erosion of the mountainside tainted the once beautiful landscape.


Waves:a disturbance on the surface of a liquid body, as the sea or a lake, in the form of a moving ridge or swell.

  • The waves of the ocean were massive

Water:a transparent, odorless, tasteless liquid, a compound of hydrogen and oxygen, H2O, freezing at 32°F or 0°C and boiling at 212°F or 100°C, that in a more or less impure state constitutes rain, oceans, lakes, rivers, etc.: it contains 11.188 percent hydrogen and 88.812 percent oxygen, by weight.

  • The water from the ocean wasn't as good to drink as the bottled water.

Wind:A bulk movement of air.

  • The wind on the mountain top was very strong compared to being on flat land. 

 Mechanical Weathering:The slow process of breaking down Earth's rocks, soil and minerals through physical components like frost, wind and tree roots with no chemical intervals

  • The pot holes in the street are caused by mechanical weathering.

 Chemical Weathering: The process of breaking down rocks, soil and minerals with water, oxygen and carbon dioxide.

  • Carbon dioxide is an example of chemical weathering.

Deposition: The natural process of layering things 

  • The deposition of sediment along the mouth of the river was great.

Glaciers: A mass of ice that moves over land

  • The glaciers shine bright under the rising sun.

Sediments: A naturally occurring process where erosion and weathering break down a naturally occurring material

  • There is a lot of sediment at the bottom of the ocean. 

Abrasion: The process of wearing down or rubbing away by means of friction.
  • The roads need to be re-paved because of the abrasion.

Oxidation: The process of oxidizing; the addition of oxygen to a compound with a loss of electrons; always occurs accompanied by reduction 

Hydrolysis: a chemical reaction in which water reacts with a compound to produce other compounds; involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water

 Carbonation: saturation with carbon dioxide (as soda water)

Acid: Any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt

Base:A bottom layer or coating

Soil: the part of the earth's surface consisting of humus and disintegrated rock

Soil profile: A vertical section through all the constituent horizons of a soil, from the surface to the relatively unaltered parent material.

Horizon:the line at which the sky and Earth appear to meet

Humus: partially decomposed organic matter; the organic component of soil

Sheet Erosion: Erosion of thin layers of surface materials by continuous sheets of running water. Also known as sheetflood erosion; sheetwash; surface wash; unconcentrated wash.

Mass Movement: The gravitationally caused downslope transport of rock, regolith, snow, or ice.

 Solifluction: Soil creep caused by waterlogged soil on top of an impermeable layer slowly moving downhill

Landform: One of the features that make up the earth's surface, such as a plain, mountain, or valley
