The longest structure, at Mission Santa Barbara, stretches 162.5 feet (49.5 m). [12] Stone ( piedra ) was used as a construction material whenever possible. In the absence of skilled stonemasons , the inexperienced builders resorted to the use of sandstone ; though easier to cut, it was not as weather-resistant as that which would have been ...
Harappan architecture is the architecture of the Bronze Age [1] Indus Valley civilization, an ancient society of people who lived during c. 3300 BCE to 1300 BCE in the Indus Valley of modern-day Pakistan and India.
Hanging valley – A tributary valley that meets the main valley above the valley floor; Headland – Landform extending into a body of water, often with significant height and drop; Highland – Area of high elevation such as a mountainous region or elevated mountainous plateau; Hill – Landform that extends above the surrounding terrain
Many of the terms are not restricted to refer to features of the planet Earth, and can be used to describe surface features of other planets and similar objects in the Universe. Examples are mountains, hills, polar caps, and valleys, which are found on all of the terrestrial planets. The scientific study of landforms is known as geomorphology.
One challenge with shaded relief, especially at small scales (1:500,000 or less), is that the technique is very good at visualizing local (high-frequency) relief, but may not effectively show larger features. For example, a rugged area of hills and valleys will show as much or more variation than a large, smooth mountain.
Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology.
In 2015, more than 11% of built-up areas globally faced high or very high flood risk, meaning areas at risk of flooding depths of at least 50 cm (17 inches) during 1-in-100-year flooding events ...
This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Bathymetry is the study of underwater relief, while hypsometry studies terrain relative to sea level.
