TRANSVERSE OR TEMPERATURE CRACK: A long crack approximately perpendicular to the centerline caused by longitudinal shortening of the bound surface layer, sometimes called temperature cracks as the shortening is often caused by contraction from temperature changes. startxref
It can also be revetment to slopes which are usually covered by water, made by laying turves on the slope according to a technique like sliced block-work.
