An aircraft (pl. aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air."

Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word aviation was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb avier (synonymous flying), itself derived from the Latin word avis ("bird") and the suffix -ation.

A church building, often simply called a church, is a building used for Christian religious activities, particularly worship services. The term in its architectural sense is most often used by Christians to refer to their religious buildings, but it is sometimes used (by analogy) for buildings of other religions. In traditional Christian architecture, the church is often arranged in the shape of a Christian cross. When viewed from plan view the longest part of a cross is represented by the aisle and the junction of the cross is located at the altar area. Towers or domes are often added with the intention of directing the eye of the viewer towards the heavens and inspiring church visitors. Modern church buildings have a variety of architectural styles and layouts; many buildings that were designed for other purposes have now been converted for church use; and, similarly, many original church buildings have been put to other uses. The earliest identified Christian church was a house church founded between 233 and 256. During the 11th through 14th centuries, a wave of building of cathedrals and smaller parish churches occurred across Western Europe. A cathedral is a church, usually Roman Catholic, Anglican, Oriental Orthodox or Eastern Orthodox, housing the seat of a bishop.

An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics, and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcanic activity, grow into atolls from coral reefs, and form from sediment along shorelines, creating barrier islands. River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. 

A lake is a naturally occurring, relatively large and fixed body of water on the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers, such as Lake Ontario. Most lakes are freshwater and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume.
