Mars (pronounced /'m?rz/) is the fourth planet from the Sun in the planetary System. The planet is name after Mars, the Roman god of war. It is also named as the "Red Planet" because of its reddish form as seen from Earth.

Mars is a terrestrial planet with a thin atmosphere, having surface features suggestive both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It is the site of Olympus Moons, the highest known mountain in the Solar System, and of Valleys Mariners, the largest canyon. In addition to its geographical features, Mars’ rotational period and seasonal cycles are likewise alike to those of Earth.

Until the first flyby of Mars by Mariner 4 in 1965, it was speculate that there might be liquid water on the planet's surface. This was based on observations of periodic variation in light and dark patches, mainly in the polar latitudes, which looked like seas and continents, while long, dark striations were interpreted by some observer as irrigation channels for liquid water. These straight line features were later proven not to exist and were instead explain as optical illusions. Still, of all the planets in our Solar System further than Earth, Mars is the most likely to harbor liquid water, and perhaps life.

The apple is the pomaceous fruit of the apple tree, variety Malus domestica in the rose family Rosaceae. It is one of the most extensively cultivated tree fruits. The tree is small and deciduous, reaching 5–12 m tall, with a broad, often thickly twiggy crown. The leaves are alternately set in simple ovals 5–12 cm long and 3–6 cm broad on a 2–5 cm petiole with an acute tip, serrated margin and a slightly downy underside. Flowers are produced in spring immediate with the budding of the leaves. The flowers are white with a pink tinge that steadily fades five petaled, 2.5-3.5 cm in diameter. The fruit matures in autumn, and is classically 5–9 cm diameter. The centre of the fruit contains five carpels given in a five-point star, each carpel containing one to three seeds.
The tree originated from Asia, where its wild forebear is still found today. There are more than 7,500 known cultivars of apples ensuing in range of desired characteristics. It should be noted however, that cultivars vary in their yield and the definitive size of the tree, even when grown on the same rootstock.

Buildings provide numerous needs of society. The human body can be continued and may effectively function only within a limited range of climatic conditions such as temperature, humidity, moisture, sunlight, and amount of oxygen and pollutants in the air. Along with access to food and drinking water, the need to make places that are protected from the outdoors and where one can happily live, work, eat, sleep, have children or engage in leisurely activities has always been a top concern for humans.
A building as a security represents a physical division of the human habitat into the inside (a place of comfort and safety) and the outside (a place that at times may be harsh and harmful). Humans have a strange drive to reproduce on their lives and express themselves through art. Ever since the first cave paintings, the buildings and everything on, inside and near buildings have become objects of creative expression. In recent years, attention on sustainable planning and building practices has improved in the U.S.
