A steep cliff that separates two level areas of differing elevation is called a "escarpment."

A dumpy level or an automatic level can be used to set out a corner with precision. These optical levels are equipped with a horizontal circle and a telescope that allow for accurate measurements and leveling of the corner point.
Chemical Level(atoms, molecules), Cellular Level(smooth muscle cell), Tissue Level(smooth muscle tissue), Organ Level(stomach), System Level(digestive system), and Organism Level.

The optical instrument made of prisms that allows an observer to see objects at a different level is called a "periscope." It is commonly used in submarines and other applications where direct line-of-sight is obstructed. By bending light through the prisms, a periscope enables viewing from a concealed or submerged position.
The low level elevation is called the lowlands and that is what i learned in my geo class
To spread cement, you typically use tools like a trowel, float, or screed. A trowel is useful for smaller areas and finishing edges, while a float helps to smooth the surface. For larger areas, a screed can be employed to level the cement evenly across the form. These tools help ensure a consistent and smooth application of the cement.
