A beach is a landform along the shoreline of an ocean, sea, lake, or river. It usually consists of loose particles, which are often composed of rock, such as sand, gravel, shingle, pebbles, or cobblestones. The particles comprising the beach are occasionally biological in origin, such as mollusc shells or coralline algae.

Wild beaches are beaches that do not have lifeguards or trappings of modernity nearby, such as resorts, camps, and hotels. They are sometimes called undeclared, undeveloped, or undiscovered beaches. Wild beaches can be valued for their untouched beauty and preserved nature. They are most commonly found in less developed areas including, for example, parts of Puerto Rico, the Dominican Republic, Thailand, the Philippines, and Indonesia, but they are also found in developed nations such as Australia and New Zealand.

Beaches typically occur in areas along the coast where wave or current action deposits and reworks sediments.

In English, the term Kalimantan refers to the Indonesian portion of the island of Borneo, while in Indonesian, the term "Kalimantan" refers to the whole island of Borneo.

The Indonesian territory makes up 73% of the island by area, and 69.5% (13,772,543 at the 2010 Census of Indonesia) by population. The non-Indonesian parts of Borneo are of Brunei (400,000) and East Malaysia (5,625,000), the latter comprising the states of Sabah and Sarawak. The region within Indonesia is also known as Indonesian Borneo.

Kalimantan's total area is 544,150 square kilometres (210,097 sq mi).

Kalimantan is divided into five provinces:

Landscape comprises the visible features of an area of land, including the physical elements of landforms such as (ice-capped) mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings and structures, and transitory elements such as lighting and weather conditions.

Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect the living synthesis of people and place vital to local and national identity. Landscapes, their character and quality, help define the self-image of a region, its sense of place that differentiates it from other regions. It is the dynamic backdrop to people’s lives.

The Earth has a vast range of landscapes including the icy landscapes of polar regions, mountainous landscapes, vast arid desert landscapes, islands and coastal landscapes, densely forested or wooded landscapes including past boreal forests and tropical rainforests, and agricultural landscapes of temperate and tropical regions.

In geology, ripple marks are sedimentary structures (i.e. bedforms of the lower flow regime) and indicate agitation by water (current or waves) or wind.
