Bridge : A bridge is a construction that allows to save a landform like a river, a canyon, a valley, a road, a railway, a body of water or any other physical obstacle. The design of each bridge varies depending on your role and nature of the land on which it is built.    

          

Moon: The Moon is the only natural satellite of the Earth. With a diameter of 3476 km is the fifth largest satellite in the solar system, while proportional in size on your planet is the largest satellite: one quarter the diameter of Earth and 1/81 its mass. After Io, is also the second densest satellite. It is in synchronous relationship with Earth, always showing thesame face to the planet.

Star : A star is all astronomical object that shines, while in technical and precise terms could say that it is a sphere of plasma that holds its shape thanks to a hydrostatic equilibrium of forces.

Galaxy : A galaxy is a collection of stars, gas clouds, planets, cosmic dust, dark matter and dark energy perhaps, united gravitationally. The number of stars that form a galaxy is uncountable, from dwarfs with 107, to the giant, with 1012 stars (according to data from NASA's last quarter of 2009). As part of a galaxy are substructures such as nebulae, star clusters and multiple star systems.

Oasis: An oasis is a desert place where you can find water and vegetation. They tend to be more or less extensive portions of land fertilized by a water fountain in the middle of the sand.

In these places can be small inhabited settlements, such as the Sahara, the Arabian Peninsula and towns such as Pica, chile, Ica in Peru or vines of the source in Mexico.

Avenue: Avenue is known as an important way of communication within a city or urban settlement. Generally an avenue has lanes in two directions, either from north to south or east to west, which differentiates it from the street.

Mountain: A mountain is a topographic eminence (ie, natural ground elevation) above 700 m over the base. The mountains are grouped except volcanoes, on ridges or hills.

Mountains cover 53% of Asia, 58% in America, 25% from Europe, 17% in Australia and 3% of Africa. In total, 24% of the solid mass is mountainous. About 10% of the world population lives in mountainous regions. All the world's major rivers are born in mountainous areas and more than half of humanity depends on water from the mountains.

Spaceship: A spaceship is a vehicle designed for space flight, in which it is played, about the conditions under which man lives on Earth.

To survive and carry out space missions, the man must take the spacecraft a good level of safety and environmental comfort. Then there are the problems of food, water and the elimination of organic waste.

Park: A park (French parc) is an area located within a population, which is devoted to grassland, woodland gardens and serving as a place for leisure and recreation of the citizens.

If it is a long stretch of natural terrain and protected by the state, we speak of a natural park or a national park.

Planet: A planet is, according to the definition adopted by the International Astronomical Union on August 24, 2006, a celestial body

According to the above definition, our solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Pluto, which until 2006 was considered a planet, is now classified as a dwarf planet, along with Ceres, also considered a planet for some time, as it was a landmark in the Titius-Bode law, and more recently considered asteroid, and Eris, an object similar to Pluto transneptunian.

Desert: A desert is a biome that receives little rainfall. They have a reputation for having little life, but that depends on the kind of desert life in many there is abundant vegetation adapts to the low humidity (desert scrub) and fauna usually hide during the day to preserve moisture.

Garden : A garden (French garden, orchard), is an area of ​​ground where plants are cultivated, with possible addition of other elements such as fountains or sculptures, for the pleasure of the senses. In Castilian was formerly called flower gardening to distinguish the garden where they grow vegetables. The adoption of the French word made ​​it easier to distinguish between the two words.

Forest : A forest (from the Germanic word busch: shrub and tree mount extension) or forest (Latin forest) is a vegetation ecosystem where trees are predominant. These plant communities cover large areas of the globe and function as animal habitats, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the biosphere of the Earth.

Cave: A cave or cavern is a natural ground cavity caused by some erosion of streams of water, ice or lava, or less commonly, a combination of several of these factors. In the most common case, the caves are formed by the dissolution of limestone by the slightly acidic water.

Village: People (from Latin populus) is the set of people in a nation, but also can be understood as part of a country, a region or a town, or even assimilated the very concept of country or locality (especially for rural population).
