Earth Element Symbols in Chinese / Japanese...

地 is the single-character element and title of the planet Earth in Chinese, old Korean Hanja, and Japanese Kanji.

Because this is a single character, the definition is a little ambiguous and can have many meanings depending on the context in which it is used. These meanings include: earth, ground, land, soil, dirt, place, territory, bottom (of a package, book, etc.), earth (one of the Japanese five elements), the region in question, the local area, skin, texture, fabric, material, weave, base, background, one's true nature, narrative (i.e. descriptive part of a story), real life, actuality, etc.

In Japanese, this Kanji can be pronounced several ways, including chi, ji, tsushi, or tsuchi.
地 is also an element of the Japanese version of the five elements (the original Chinese version uses a different version of earth).

金木水火土 is a list of the Chinese characters for the five elements in a comfortable order (meaning that they “feel right” to a Chinese person who views this arrangement).

The order is metal, wood, water, fire, and earth.

Note that sometimes the metal element is translated as gold. And earth refers to soil versus the whole planet earth.

五行 is the title of the five elements: wood, fire, water, earth, and metal.

The first character means five, and the second character is simply element(s).

According to ancient Chinese science, all matter in the world is comprised of these elements. One idea presented with the five elements is that when energy is added, the matter is believed to expand. When energy is removed, matter contracts. Oddly, this concept is not far from Einstein's theories and modern science. Just a few thousand years before Einstein.
