Falling for you
This category of mass wasting is characterised by free falls of earth materials
What is a fall?
A general term for planes of weaknesses in rocks.
What are discontinuities?
This type of strain is non-permanent.
What is elastic strain?
This is the weakest category of earth materials.
What are soils?
These are representative of atmospheric temperature change over large areas and distances.
What are temperature anomalies?
This category of mass wasting is characterised by movement of blocks of material down a defined failure surface.
What is a slide?
This type of discontinuity describes a change in lithology in sedimentary rocks.
What is a bedding plane?
The ultimate strength of intact rocks is determined by the amount of uniaxial stress you can apply to a core before this type of strain occurs.
What is brittle deformation or fracture?
Rocks with this texture are the strongest.
What is crystalline/aphanitic?
The position of Earth relative to the sun changes according to these cycles.
What are Milankovitch cycles?
This type of mass movement is characterised by imperceptibly slow, discrete movements of particles downslope.
What is creep?
This type of discontinuity describes a fracture where there is no movement of the rocks on either side.
What is a joint?
Rocks will tend to experience this type of strain when stress is applied over a long period of time.
What is ductile or plastic?
This rating system describes the ratio of core lengths greater than 10 cm to the total length of the core.
What is the Rock Quality Designation (RQD)?
The solar cycle has historically been tracked based on observations of the number of these.
What are sun spots?
This category of mass wasting occurs in loose, saturated sediment.
What is a flow?
This word describes discontinuities that dip in the same direction as the slope of an outcrop.
What is daylighting?
What is ductile or plastic deformation?
This rating system uses observations about rocks to semi-quantitatively categorize them into one of five classes.
What is Rock Mass Rating (RMR)?
This natural process transfers carbon from the geosphere to the atmosphere.
What is volcanism?
The Indonesian term describing fast flows of volcanic ash.
What is a lahar?
The strength of discontinuities is evaluated by applying this type of stress.
What is shear stress?
Deeply buried rocks experience equal pressure in all directions, known as ______.
What is confining pressure?
This force holds claystone, mudstones, shales and soils together
What is van der Waals bonding?
These occur when several solar cycles exhibit less than average activity for decades to centuries.
What are grand solar minima?
