Sandstone in the context of "Tendaguru Formation"

Sediment is a solid material made of loose particles that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification.

Sediments are most often transported by water (fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and river channel deposits are examples of fluvial transport and deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. Glacial moraine deposits and till are ice-transported sediments.

The Belogradchik Rocks (Bulgarian: Белоградчишки скали, Belogradchishki skali) are a group of strangely shaped sandstone and conglomerate rock formations located on the western slopes of the Balkan Mountains (Stara Planina) near the town of Belogradchik in northwest Bulgaria. The rocks vary in color from primarily red to yellow; some of the rocks reach up to 200 m in height. Many rocks have fantastic shapes and are associated with interesting legends. They are often named after people or objects they are thought to resemble. The Belogradchik Rocks have been declared a Natural Landmark by the Bulgarian government and are a major tourist attraction in the region. They are the only habitat of the critically endangered Bulgarian endemic plant Hieracium belogradcense.

In geography and geology, a cliff or rock face is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.

An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers.

Petra (Arabic: ٱلْبَتْراء‎, romanized: Al-Batrāʾ; Ancient Greek: Πέτρα, lit. 'Rock'), originally known to its inhabitants as Raqmu (Nabataean Aramaic: 𐢛𐢚𐢒‎ or 𐢛𐢚𐢓𐢈‎, *Raqēmō), is an ancient city and archaeological site in southern Jordan. Famous for its rock-cut architecture and water conduit systems, Petra is also called the "Rose City" because of the colour of the sandstone from which it is carved. The city is one of the New 7 Wonders of the World and a UNESCO World Heritage Site.

The area around Petra has been inhabited from as early as 7000 BC, and was settled by the Nabataeans, a nomadic Arab people, in the 4th century BC. Petra would later become the capital city of the Nabataean Kingdom in the second century BC. The Nabataeans invested in Petra's proximity to the incense trade routes by establishing it as a major regional trading hub, which gained them considerable revenue. Unlike their enemies, the Nabataeans were accustomed to living in the barren deserts and thus were able to defend their kingdom. They were particularly skillful in agriculture, stone carving, and rainwater harvesting.

The Kunsthistorisches Museum Wien (lit. "Vienna Museum of Art History", often referred to as the "Museum of Fine Arts, Vienna") is an art museum in Vienna, Austria. Housed in its festive palatial building on the Vienna Ring Road, it is crowned with an octagonal dome. The term Kunsthistorisches Museum applies to both the institution and the main building. It is the largest art museum in the country.

Emperor Franz Joseph I of Austria-Hungary opened the facility around 1891 at the same time as the Natural History Museum, Vienna which has a similar design and is directly across Maria-Theresien-Platz. The two buildings were constructed between 1871 and 1891 according to plans by Gottfried Semper and Baron Karl von Hasenauer. The emperor commissioned the two Ringstraße museums to create a suitable home for the Habsburgs' formidable art collection and to make it accessible to the general public. The buildings are rectangular, with symmetrical Renaissance Revival façades of sandstone lined with large arched windows on the main levels and topped with octagonal domes 60 metres (200 ft) high. The interiors of the museums are lavishly decorated with marble, stucco ornamentation, gold-leaf, and murals. The grand stairway features paintings by Gustav Klimt, Ernst Klimt, Franz Matsch, Hans Makart and Mihály Munkácsy.

The Early Dynastic Period, also known as Archaic Period or the Thinite Period (from Thinis, the hometown of its rulers), is the era of ancient Egypt that immediately follows the unification of Upper and Lower Egypt in c. 3150 BC. It is generally taken to include the First Dynasty and the Second Dynasty, lasting from the end of the archaeological culture of Naqada III until c. 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the Egyptian capital moved from Thinis to Memphis, with the unified land being ruled by an Egyptian god-king. In the south, Abydos remained the major centre of ancient Egyptian religion; the hallmarks of ancient Egyptian civilization, such as Egyptian art, Egyptian architecture, and many aspects of Egyptian religion, took shape during the Early Dynastic Period.

Before the unification of Egypt, the land was settled with autonomous villages. With the early dynasties, and for much of Egypt's history thereafter, the country came to be known as "The Two Lands" (referencing Upper and Lower Egypt). The pharaohs established a national administration and appointed royal governors, and buildings of the central government were typically open-air temples constructed of wood or sandstone. The earliest Egyptian hieroglyphs appear just before this period, though little is known of the spoken language that they represent.

Trier (/trɪər/ TREER, German: [tʁiːɐ̯] ; Luxembourgish: Tréier [ˈtʀɜɪ̯ɐ] ), formerly and traditionally known in English as Trèves (/trɛv/ TREV, French: [tʁɛv] ) and Triers (see also names in other languages), is a city on the banks of the Moselle in Germany. It lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region.

Founded by the Romans in the late 1st century BC as Augusta Treverorum ("The City of Augustus among the Treveri"), Trier is considered Germany's oldest city. It is also the oldest seat of a bishop north of the Alps. Trier was one of the four capitals of the Roman Empire during the Tetrarchy period in the late 3rd and early 4th centuries. In the Middle Ages, the archbishop-elector of Trier was an important prince of the Church who controlled land from the French border to the Rhine. The archbishop-elector of Trier also had great significance as one of the seven electors of the Holy Roman Empire. Because of its significance during the Roman and Holy Roman empires, several monuments and cathedrals within Trier are listed as a UNESCO World Heritage Site.

A pyramidion (plural: pyramidia) is the capstone of an Egyptian pyramid or the upper section of an obelisk. Speakers of the Ancient Egyptian language referred to pyramidia as benbenet and associated the pyramid as a whole with the sacred benben stone.

Pyramidia were usually made of limestone, sandstone, basalt or granite, and were sometimes covered with plates of copper, gold or electrum. From the Middle Kingdom onward, they were often "inscribed with royal titles and religious symbols".

• A ″ natural material a substance that comes from plants, animals, or the earth, and has not been made by humans.. Minerals and the metals that can be extracted from them (without further modification) are also considered to belong into this category. Natural materials are used as building materials and clothing. Types include:

• Biotic materials
  • Wood (rattan, bamboo, bark, etc.)
• Plant fiber (coir, ramie, sisal, cotton, flax, hemp, jute, kapok, kenaf, moss, linen, abacá, etc.)
