Weathering And Soil

Front 1

Chemical Weathering

Back 1

breakdown of rock's composition caused by the effects of chemicals on them

Front 2

Climate

Back 2

the normal expected type of weather in a particular area...as observed over a long period of time

Front 3

Desertification

Back 3

the gradual transformation of an area into a desert

Front 4

Back 4

one of the three layers of soil that cover most areas of the Earth

Front 5

hummus

Back 5

organic matter in the soil that is dark and composed of decayed organisms

Front 6

ice wedging

Back 6

a type of mechanical weather in which freezing water expands from inside rocks...splitting them open

Front 7

leaching

Back 7

soild materials move from one horizon to another after being dissolved and transported by water passing through the soil layers

Front 8

mechanical weathering

Back 8

breakdown of rock where chemical state of rock is not affected

Front 9

oxidation

Back 9

chemical weathering that inovlves water and oxygen

Front 10

soil

Back 10

combination of decayed plant and animal matter, minerals, sediment and air that covers the uppermost layers of the ground

Front 11

soil profile

Back 11

a section of the soil in which the distinct layers can be observed

Front 12

weathering

Back 12

process by which rocks deteriorate or disintigrate into smaller pieces due to mechanical or chemical processes
