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.
Definition of Trapezoid. A trapezoid is a quadrilateral with only one pair of parallel sides. As shown in the picture below, the parallel sides of trapezoid ABCD are called bases and the sides that are not parallel are called legs. The degree measure of the four angles add up to 360 degrees. This is actually true of any quadrilateral.
