Each row of concrete blocks is called a:

1. beam

2. course

3. layer

4. tier

The correct answer is: beam

Each row of concrete blocks is called a "course." In masonry terminology, a course refers to a horizontal row of bricks, blocks, or stones that are stacked one on top of the other. This term is commonly used in construction to describe the layers of materials that make up a structure. While the terms "beam," "layer," and "tier" are all related to construction terminologies, they do not specifically refer to a row of concrete blocks in this context. - A beam is a structural element that carries loads and spans an open space between supports. - A layer typically refers to a single sheet or thickness of material that is laid on top of another as part of a building process. - A tier usually refers to a level or stage in a structure that is higher or lower than another.
