also: おか
noun
Refers to land as opposed to sea or air; also specifically the shore or coast. Common in compounds like 陸地 (rikuchi) and 上陸 (jōriku).

Kana spelling is common in everyday writing, especially when the intended meaning is clear from context.
The kanji 陸 originally depicts a hill or mound and came to mean 'land' as opposed to water. The reading りく is the on'yomi, while おか is a rare kun'yomi.
