Furrows

Falling rocks tend to form furrows in a mountain face, and these furrows ( couloirs ) have to be ascended with caution, their sides often being safe when the middle is stoneswept.

Its head's ventral surface lacks the numerous prominent furrows of the related rorquals, instead bearing two to five shallow furrows on the throat's underside.

This offset the drainage advantages of short furrows and meant furrows were made as long as possible.

Scallopers tow massive steel dredges that cut furrows through the ocean bottom and snatch scallops along the way.

Her brow furrows in response and she hobbles away to prune her banana trees with a machete.

Re-tilled furrows wait for a sprout to appear, and a new generation of hungry leafhoppers peek in from the edges — from their blade-eye perspective, the whole world is beginning anew.

According to him, when the team left the site, the pavement was turned completely ‘upside down’ with heaps of mud spread over the road and half a metre of deep furrows from the trench digger’s tyres.

A brow or forehead lift smooths away wrinkles and deep furrows in the forehead.

Furrows in the stems of some cacti increase surface area for photosynthesis, but still expose far less surface area to the weather than individual leaves would.

No heavy bags hang under her eyes, no wrinkles pull at her skin, and no deep furrows line her forehead.

As the plough is drawn through the soil it creates long trenches of fertile soil called furrows.

Caecilians are unique among amphibians in having mineralized dermal scales embedded in the dermis between the furrows in the skin.

Depending on the size of the implement, and the number of furrows it is designed to plough at one time, a forecarriage with a wheel or wheels (known as a furrow wheel and support wheel) may be added to support the frame (wheeled plough).

For ploughs with two or more furrows more than two horses are needed and, usually, one or more horses have to walk on the loose ploughed sod and that makes hard going for them, and the horse treads the newly ploughed land down.

However, when the tunnels are near the surface, they collapse when the ground is soft after heavy rain and leave unsightly furrows in the lawn.

In many mammals, the cerebral cortex consists of folded bulges called gyri that create deep furrows or fissures called sulci.

In this way adjacent furrows can be ploughed in opposite directions, allowing ploughing to proceed continuously along the field and thus avoiding the ridge and furrow topography.

The ard does not clear new land well, so hoes or mattocks must be used to pull up grass and undergrowth, and a hand-held, coulter -like ristle could be used to cut deeper furrows ahead of the share.

The hand-hoers are again set to work, and every weed and superfluous turnip is cut up; afterward the horse-hoe is employed to separate the earth, which it formerly threw into the furrows, and lay it back to the sides of the drills.

The orientation of furrows (relative to the original tetrad of microspores) classifies the pollen as sulcate or colpate.
