Weathering

The force of nature acting upon an object, resulting in the physical aspects of the object being changed.

Ex: Wind and water have created interesting patterns into these rocks.

Sediment

Small, rock particles that have been broken down by weather and get washed along by wind and water.

Ex: The ocean creates sediment by pounding against rocks repeatedly. This sediment usually washes up onto shore by waves.

Mechanical Weathering

Mechanical weathering is the process of strong weather changing the physical appearances of objects over time.

Ex: These rocks have become rough and jagged because of the constant weathering from the water they are surrounded by.

Chemical Weathering

Chemical weathering is the process in which the weather suspended upon the object slowly changes its' chemical composition, breaking it down, and changing it.

Ex: Oxidation has changed this metal by breaking it down, changing its' color, and even make it want to crack and seperate.

Erosion

Erosion is the process in which weather moves soil from one place to another.

Ex: Water has eroded all the rock bellow and slowly, over time, created deep canyons.

Delta

A delta is a deposit of sediment from water that is usually in the shape of a triangle and directs a river in separate directions.

Loess

Loess is a deposit of sediment from the wind.

Ex: This sand has been collected by the wind and formed small hillsides.

Glacier

A huge formation of thick ice.

Ex: These formations of ice, if touched by land, can slide downhill and gather sediment to carry along their path.

Glaciation

Glaciation is result of land becoming covered by ice.

Ex: This entire hillside has become covered in a mixture of snow and ice.

Moraine

Moraine is the materials being gathered and deposited by glaciers.

Ex: As glaciers melt and slide around, they leave behind sediment.

Humus

The nutrient soil due to the decomposition of plants and animals.

Ex: This tree has decomposed and left nutrients for other plants to grow.
