By: Ashley RandleWeatheringWhat Is It ?

Weathering is when surface processes work to break down rock.Weathering Mountain

Growing tree roots can grow in the cracks and break the rock apart.

Occurs when rocks are broken apart by physical processes. This means that the overall chemical makeup of the rock stays the same.Mechanical Weather

Example-When the trees near the sidewalk and the cement is pushed up.

Ice WedgingDefinition: occurs in temperature and cold climates where water enters cracks and freezes.

Example: Most noticeable in the mountains.

By: Moraima RiveraBy: Michael SalerChemicalweathering1.The erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.2. Grand canyon

OxidationA chemical reaction in which oxygen is added to an element or compound.(Bing Definitions)

You can find oxidation in rusts. Next time you leave your shovel outside, check out the rust!Definition:Climate is the pattern of weather that occurs in a particular area over many years.ClimateExample: Hot climates tend to increase the rates of chemical reactions.

SoilSoil is a mixture of weathered rock, decayed organic matter, mineral fragments, water, and air.

Soil profile

The Horizons of a soil form a soil profile.

Horizon- Each layer in a soil profile

Mya OdrickHumusServes as a source of nutrients for plants.

Leaching: is the removal of minerals that have been dissolved in water.For example, the process of leaching is similar to weathering because water will carry away the nutrients and elements leaving it different over time..

LitterConsists of leaves, twigs, and other organic material that can be changed to humus by decomposing organisms.

Definition : The picking up and moving sediment or soil.

Example : River Erosion.Erosion

OvergrazingOvergrazing is a proses in which domestic animals such as sheep or cattle degrade the land by eating more plant material then the land can sustain.

TerracingDefinition: Method in which steep-sided, level topped areas are built onto the sides of steep hills and mountains so that crops can be grown

Terracing had been used in the Philippines, Japan, China, and Peru for centuries
