Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers which are called agents of denudation.
A cuboid is a box-shaped solid object. It has six flat sides and all angles are right angles. And all of its faces are rectangles.
A spheroid, or ellipsoid of revolution, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. If the ellipse is rotated about its major axis, the result is a prolate spheroid, shaped like an American football or rugby ball. If the ellipse is rotated about its minor axis, the result is an oblate spheroid, shaped like a lentil. If the generating ellipse is a circle, the result is a sphere. A spheroid has ci
