Oxidation occurs when oxygen in the air combines with minerals within a rock to form new chemical compounds. Rust is an example of oxidation. Oxygen is abundant in the atmosphere, but oxidation occurs slowly unless water is present. Oxygen dissolved in water causes most oxidation weathering. Hydro...

Denudation rates of tropical mountain regions : What is the proportion of chemical weathering vs. mechanical denudation in a tectonically active settings?C. RoelandtV. VanackerY. GoddérisJ. O. KaplanEGU General Assembly Conference Abstracts
Weathering is the gradual breaking down of rocks into smaller pieces without altering their chemical makeup, due to changes in temperature; when rocks expand when heated up and contract when chilled down again, breaking apart into individual fragments. Erosion causes rocks to erode away and form n...
Resulting global CO 2-consumption by chemical weathering is similar to earlier estimates (237Mt C a 1) but the proportion of silicate weathering is 63%, and thus larger than previous estimates (49 to 60%). The application of the enhanced lithological classification scheme reveals that it is ...
A canyon is a deep and narrow valley consisting of steep sides created by weathering and erosion by rivers, wind, rain and tectonic activity. Rivers have a natural capability to gorge through underlying surfaces, so they will ultimately weather and carry away rock layers. Over time, their botto...
What type of weathering creates karst topography? What is a deposit of fertile windblown soil called? What geologic processes caused aquifers to form? Which type of erosion can cause mudslides? What is a karst aquifer? Are there U.S. policies about soil degradation?
Rainwater is slightly acidic and gradually wears away at rocks such as granite or limestone over time, due to carbon dioxide combining with water as raindrops fall from the atmosphere. Chemical weathering can be enhanced by adding pollutants that produce sulfuric or nitric acids that form acid rain...
