Weathering Vocabulary

Front 1

Weathering

Back 1

Weathering is the chemical and physical processes that change the characteristics of rocks on the Earth'ssurface

Front 2

Erosion

Back 2

A type of weathering in which surface soil and rock are worn away through the action of glaciers, water, and wind.

Front 3

Sand Dune

Back 3

A ridge of sand created by the wind; found in deserts or near lakes and oceans

Front 4

Suspension

Back 4

A mixture in which small particles of a substance are dispersed throughout a gas or liquid.

Front 5

Leeward

Back 5

On the ​side away from the ​wind, or in the ​direction toward which the ​wind is ​blowing.

Front 6

Windward

Back 6

The direction the wind is blowing

Front 7

Slip Face

Back 7

The steep side of a sand dune.

Front 8

Abrasion

Back 8

The mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, glacier, waves, gravity, running water or erosion.

Front 9

Deflation

Back 9

When the grond lowers do to erosion.

Front 10

Zone Of Saturation

Back 10

The zone of saturation is the area beneath the water table where all pore spaces are completely filled with water.

Front 11

Zone Of Aeration

Back 11

The zone between the land surface and the water table in which the pore spaces between soil and rock particles contain water, air, and/or other gases.

Front 12

Bedrock

Back 12

The layer of rock in earth's surface that water cannot pass through.

Front 13

Water Table

Back 13

The level below which the ground is completely saturated with water.

Front 14

Porosity

Back 14

Porosity is a measure of how much of a rock is open space.

Front 15

Permeability

Back 15

A measure of the ability of a porous material to allow fluids to pass through it.

Front 16

Exfoliation

Back 16

The peeling away of large sheets of loosened materials at the surface of a rock.

Front 17

Chemical Weathering

Back 17

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.

Front 18

Physical Weathering

Back 18

Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition.
