The three-dimensional orientation of a line can be described with just a plunge and trend. The rake is a useful description of a line because often (in geology) features (lines) follow along a planar surface. In these cases the rake can be used to describe the line's orientation in three dimensions relative to that planar surface.
A rake (Old English raca, cognate with Dutch hark, German Rechen, from the root meaning "to scrape together", "heap up") is a broom for outside use; a horticultural implement consisting of a toothed bar fixed transversely to a handle, or tines fixed to a handle, and used to collect leaves, hay, grass, etc., and in gardening, for loosening the ...
The orientation of the lineation can then be calculated from the rake and strike-dip information of the plane it was measured from, using a stereographic projection. If a fault has lineations formed by movement on the plane, e.g.; slickensides, this is recorded as a lineation, with a rake, and annotated as to the indication of throw on the fault.
When studying subsurface features, a dipmeter can be used. A dipmeter is a tool that is lowered into a borehole, and has arms radially attached which can detect the microresistivity of the rock. By recording the times at which the rock's properties change across each of the sensors, the strike and dip of subsurface features can be worked out. [12]
Pests such as mice and voles can also use the leaves to thrive, according to the University of Minnesota, which may create more problems for homeowners down the road.. Allowing some leaves to ...
A stone picker (or rock picker) is an implement to sieve through the top layer of soil to separate and collect rocks and soil debris from good topsoil. It is usually tractor-pulled. [1] A stone picker is similar in function to a rock windrower (rock rake); a stone picker generally digs to greater depths to remove stones and rocks.
Inorganic mulches, like rock and gravel, can be a better choice in regions where fire is a hazard. However, they tend to heat up quickly, harming plant and tree roots. ... Rake it back in spring ...
