|---|---|---|---|---|---|
| Erosion | movement of rocks particles by wind, water, ice or gravity
🗑
|
||||
| mechanical weathering | rock is physically broken insto smaller pieces
🗑
|
||||
| mechanical weathering(2) | breaks rock into pieces by freezing and thawing, heating and cooling, growth of plants, actions of animals, and abrasions
🗑
|
||||
| abrasion | grinding away of rock by rock particles carried by water, ice, wind, or gravity.
🗑
|
||||
| ice wedging | water expands when it freezes causing rocks to crack
🗑
|
||||
| chemical weathering | process that breaks down rock through chemical changes
🗑
|
||||
| agents of chemical weathering | water, oxygen, carbon dioxide, living organims, and acid rain
🗑
|
||||
| water | most important agent of chemical weathering
🗑
|
||||
| oxygen | the gas in air is an important part of chemical weathering
🗑
|
||||
| rust | product of oxidation
🗑
|
||||
| Rust(2) | makes rocks soft and crumbly, gives it a red/brown color
🗑
|
||||
| carbon dioxide | a gas found in air, carbon dioxide, causes chemical weathering
🗑
|
||||
| weak acid | carbonic acid
🗑
|
||||
| carbonic acid | weathers marble and limestone
🗑
|
||||
| living organisms | roots push into cracks in the rock
🗑
|
||||
| lichens | plantlike organisms that grow on rock
🗑
|
||||
| acid rain | polllution in the air with sulfur, carbon, and nitrogen compunds
🗑
|
||||
| acid rain(2) | very rapid chemical weathering
🗑
|
||||
| rate at which weathering occurs | type of rock and climate
🗑
|
||||
| permeable | material is full of tiny, connected air spaces taht allow water to seep through it
🗑
|
||||
| climate | average weather conditions in an area
🗑
|
||||
| wet climates | both chemical and mechanical weathering occur fast
🗑
|
||||
| chemical reactions | faster at higher temperatures
🗑
|
||||
| granite | very hard rock
🗑
|
||||
| soil | loose, weathered materialon earth's surface
🗑
|
||||
| soil(2) | forms as rock is broken down by weathering and mixes with other materials on the surface
🗑
|
||||
| bedrock | solid layer of rock beneath the soil
🗑
|
||||
| soil is a mixture of | rock particles, minerals, decayed organic material, air and water
🗑
|
||||
| humus | decayed organic material in soil
🗑
|
||||
| humus (2) | forms as plant and animal remains decay
🗑
|
||||
| humus(3) | rich in nitrogen
🗑
|
||||
| soil texture | important for plant growth
🗑
|
||||
| loam | soil that is made up of about equal parts of clay, sand, and silt
🗑
|
||||
| soil horizon | layer of soil that differs in color and texture from the layers above or below it
🗑
|
||||
| A horizon | made up of topsoil
🗑
|
||||
| top soil | a crumbly, dark brown soil that is a mixture of humus, clay, and other minerals
🗑
|
||||
| B horizon | subsoil
🗑
|
||||
| subsoil | consists of clay and other particles washed down from the A horizon, littel humus
🗑
|
||||
| C horizon | contains only partly wetahered rock
🗑
|
||||
| C horizon (2) | bedrock
🗑
|
||||
| B Horizon develops | as rainwater washes clay and minerals from the other horizons
🗑
|
||||
| C horizon forms | as bedrock weathers and rock breaks up into soil particles
🗑
|
||||
| A horizon develops | from the C horizon when plant roots weather the rock
🗑

🗑
|
||||
| clay | smallest soil particle
🗑
|
||||
| air and water | make up the major portion of loam
🗑

||||
| A horizon consists of | topsoil with humus
🗑
|
||||

🗑
|
||||
| C horizon consists of | rock fragments
🗑
|
||||
| bacteria | decomposers taht break down animal and plant remains and wasts
🗑
|
||||
| fungi | are decomposers that send out long, rootlike threads that digest plant remains
🗑
|
||||
| earthworms | break up hard, compacted soil
🗑
|
||||
| an area's climate and plant life | determine what type of soil froms from bedrock
🗑
