A city is a relatively large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town within general English language meanings, many cities have a particular administrative, legal, or historical status based on local law. Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation.
A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers.
Dummy text is text that is used in the publishing industry or by web designers to occupy the space which will later be filled with ‘real’ content. This is required when, for example, the final text is not yet available. It is said that song composers of the past used dummy texts as lyrics when writing melodies in order to have a ready-made text to sing with the melody.
Summer is the warmest of the four temperate seasons, falling between spring and autumn. At the summer solstice, the days are longest and the nights are shortest, with day-length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition and culture, but when it is summer in the Northern Hemisphere it is winter in the Southern Hemisphere, and vice versa.
