Chapter 2 Vocabulary

Rock is composed of such primary minerals as light-colored quartz, muscovite , and feldspar and dark-colored biotite, augite, and hornblende

• Sedimentary

• Igneous

• Temperature (physical weathering)

• Metamorphic

A rock formed from materials deposited from the decomposition of a primary mineral or from the reprecipitation of the products of decomposition of a primary mineral.  

• Sedimentary

As the earth’s continental plates sift , and sometimes collide, forces and generated that can uplift great mountain ranges or cause huge layers of rock to pushed deep into the crust.

Temperature (physical weathering)

• The peeling away of outer layers.

• Heating rocks by sunlight  or fires cause expansion of their constituent minerals.

• When loaded with sediment water has tremendous cutting power , as is amply demonstrated by the gorges, ravines and valleys around the world. Weather can cause many of the of our land marks.

• Plant roots sometimes enter cranks in rocks and pry them apart , resulting in some disintegration. Burring animals may also help disintegrate  rocks somewhat.

Exfoliation

• The peeling away of outer layers.

• Heating rocks by sunlight  or fires cause expansion of their constituent minerals.

• When loaded with sediment water has tremendous cutting power , as is amply demonstrated by the gorges, ravines and valleys around the world. Weather can cause many of the of our land marks.

• Plant roots sometimes enter cranks in rocks and pry them apart , resulting in some disintegration. Burring animals may also help disintegrate  rocks somewhat.

Abrasion by water, ice, and wind (physical weathering)

• The peeling away of outer layers.

• Heating rocks by sunlight  or fires cause expansion of their constituent minerals.

• When loaded with sediment water has tremendous cutting power , as is amply demonstrated by the gorges, ravines and valleys around the world. Weather can cause many of the of our land marks.

Biogeochemical weathering

• Develops in place from weathering of the underlying rock.

• Is made up of poorly sorted rock fragments detached from the heights above and carried downslope , mostly by gravity, assisted in some case by frost action. 

• Chemical weathering is enhanced by such geological agents as the presence of water and oxygen , as well as by such biological agents as the acids produce by microbial and plant -root metabolism 

• It a plain that incase it happen is to minimums the effected loss.
