Mechanical Weathering
100
internal forces gradually raise some constantly changing parts of the surface through mountain building and volcanic activity
What is Earth's Surface Doing ?
100
Climate.
What is the greatest effect on soil formation ?
100
Transfer of rock and soil downslope due to gravity .
What is mass movement ?
100
Transformation of rock into one rock or more new compounds .
What is chemical weathering ?
100
When physical forces break rocks into smaller and smaller pieces without changing the rock's mineral composition .
What is Mechanical Weathering ?
200
Chemical Weathering and Mechanical Weathering
What are two types of weathering ?
200
Weathering produces a layer of rock and mineral fragments
What is regolith and where can it be found ?
200
Stream Valleys
What is what are the most common earth landforms ?
200
Water
What is the most important agent of chemical weathering ?
200
frost wedging , unloading and biological activity
What is three physical processes that are responsible for mechanical weathering in nature ?
300
Yes.
What is does each new piece have the same characteristics of the original rock ?
300
Part of the regolith that supports the growth of plants .
What is Soil ?
300
Saturation of surface , Materials with water , overstepping of slopes , removal of vegetation , and earthquakes .
What is four factors that commonly trigger mass movement ?
300
Rust that forms when iron containing objects are exposed to water .
What is iron oxide ?
300
the mechanical breakup of rock caused by the expansion of freezing water in cracks and crevices (Freeze -Thaw Cycle )
What is frost wedging and what causes it ?
400
Spherodial ---- Takes on a spherical shape Unloading ---- Pressure exerted on the igneous rock is reduced .
What is the difference between spherodial weathering and unloading ?
400
Composition , Texture And Structure .
What is list the three important characteristics of soil ?
400
Weathering and Mass Movement .
What is the combination produces most landforms ?
400
When rain falls through the atmosphere .
What is how does carbonic acid forms ?
400
Large masses of igneous rock exposed through uplift and erosion of overlaying rocks .
What is unloading and what does it cause ?
500
Sections of rock that are wedged loose and may tumble into large piles
What is Talus ?
500
Residual Soil .
What is soil that forms on a Bedrock called ?
500
Slides that include segments of bedrock .
What is a rock slide ?
500
Different parts of a rock mass often weathers at different rates .
What is differential weathering ?
500
Slabs of outer rock separate like the layers of an onion and break loose .
