Fissure vs. Crevasse — What's the Difference?

In anatomy, a fissure (Latin fissura, plural fissurae) is a groove, natural division, deep furrow, elongated cleft, or tear in various parts of the body. It is also generally called a sulcus, but this term can also reffer specifically to the analagous brain structure.

A crevasse is a deep crack, crevice or fissure found in an ice sheet or glacier, or earth. Crevasses form as a result of the movement and resulting stress associated with the shear stress generated when two semi-rigid pieces above a plastic substrate have different rates of movement.

A long narrow opening; a crack or cleft.

A deep fissure, as in a glacier; a chasm.

The process of splitting or separating; division.

A crack or breach in a dike or levee.

A separation into subgroups or factions; a schism.

To develop or cause to develop crevasses.

(Anatomy) A normal groove or furrow, as in the liver or brain, that divides an organ into lobes or parts.

A crack or fissure in a glacier or snowfield; a chasm.

(Medicine) A break in the skin, usually where it joins a mucous membrane, producing a cracklike sore or ulcer.

(US) A breach in a canal or river bank.

To form a crack or cleft or cause a crack or cleft in.

(by extension) Any cleft or fissure.

A long, narrow crack or opening made by breaking or splitting, especially in rock or earth.

(figuratively) A discontinuity or “gap” between the accounted variables and an observed outcome.

(anatomy) A groove, deep furrow, elongated cleft or tear between body parts or in the substance of an organ; a sulcus.

(intransitive) To form crevasses.

(anatomy) A break or slit in tissue usually at the junction of skin and mucous membrane.

(transitive) To fissure with crevasses.

A state of incompatibility or disagreement.

A deep crevice or fissure, as in embankment; one of the clefts or fissure by which the mass of a glacier is divided.

To split, forming fissures.

A breach in the levee or embankment of a river, caused by the pressure of the water, as on the lower Mississippi.

A narrow opening, made by the parting of any substance; a cleft; as, the fissure of a rock.

A deep fissure

To cleave; to divide; to crack or fracture.

A long narrow depression in a surface
