Rocks And Weathering Flashcards
Erosion
Erosion is the removal of rock particles by wind, water, ice, or gravity.
Weathering
Weathering is the process that breaks down rock and other substances at Earth’s surface.
Uniformitarianism
Uniformitarianism is a principle that states that the same processes that operate today operated millions of years ago.
Mechanical weathering
The type of weathering in which rock is physically broken into smaller pieces is called mechanical weathering.
Abrasion
The term abrasion refers to the grinding away of rock by rock particles carried by water, wind,mice, or gravity.
Ice wedging
The process of wedges of ice in rocks widen and deepen cracks.
Chemical weathering
Chemical weathering is the process that breaks down rock through chemical changes.
Oxidation
Iron combines with oxygen in the presence of water in a process called oxidation.
Permeable
Permeable means that a material is full of tiny, connected air spaces that allow water to seep through it.
