Land areas refer to the surface of the Earth that is not covered by water. They include various types of landscapes such as mountains, forests, deserts, and plains. Land areas are measured in units like square kilometers or acres, and they can vary greatly in size, from small parks to entire countries. Different land areas support diverse ecosystems and human activities. For example, agricultural land is used for farming, while urban areas are developed for cities and towns. Understanding land areas is essential for planning, conservation, and managing natural resources effectively.
