Earthwork

A type of art that emerged in the late 1960s. Using materials such as mud, rocks, and metal, earthwork artists often created their work in the natural landscape. Earthworks change over time due to natural processes such as wind, rain, or soil erosion.

Elevated train

Elevated railways were made of iron or steel stilts and built thirty feet above the streets. The first New York City elevated train—known as the El or L—was constructed in 1867-70. By the 1930s, more efficient subways caused the Els to almost disappear. Elevated railways remain in use today in Brooklyn, Queens, and the Bronx.

Embroidery floss

Embroidery floss

A type of yarn made for needlework. Embroidery is the art of decorating fabric or other materials with a needle and thread or embroidery floss.

Emulator

A copycat or someone who copies the words or behavior of another. An emulator is also a computer program that copies other computer programs.

Engineer

A person who uses science to solve problems, such as how to design, construct, and operate machines or build bridges.

Enlarging

Enlarging is making something bigger.

Entertainment

Something that is fun, amusing, or engaging, such as a performance or a movie.

Erosion

The wearing away of earth or rocks in the environment by natural processes such as wind, water, or ice.

Etching

A printing process in which a metal plate is coated with a material called a “ground.” The artist draws through the ground with a sharp needle-like tool, exposing the metal plate underneath. When the plate is put into an acid bath, the exposed parts are eaten away (etched), producing sunken lines that will receive the ink to make a print. The plate is then inked and pressed against paper to produce a print.
