burial metamorphism
Earth science; Geology
Takes place in an environment where pressure and temperature are barely more intense than during diagenesis , typically in a deepening sequence of sediments.
block disintegration
Earth science; Geology
This is to do with mechanical / physical weathering breaking down rock along its weak points (such as joints or bedding planes). An example would be 'frost shattering*.
altimeter
Earth science; Geology
An instrument that indicates the altitude (1) of an object with respect to a reference level such as sea level; examples include pressure altimeters and radio altimeters
base level
Earth science; Geology
Of a stream is the point below which the stream cannot cut. A temporary base level along a stream, such as a lake may be removed by stream action . Ultimate base level is the ...
continentality
Earth science; Geology

Earth science; Geology
