People have used hills for homes and urban areas for thousands of years. Many people have built their homes and villages on hills to avoid floods. The higher elevation also allows people to defend themselves. Ancient Rome, for example, was built on the city's seven hills so Romans could see their invaders coming from far away.

Why do we need hills in the army?
Hills provide a major advantage to an army, giving them an elevated firing position and forcing an opposing army to charge uphill to attack a fort or other position. They may also conceal forces behind them, allowing a force to lie in wait on the crest of a hill, using that crest for cover, and firing on unsuspecting attackers as they broach the hilltop. As a result, conventional military strategies often demand possession of high ground.
How high are mountains?
Geographers historically regarded mountains as hills greater than 1,000 feet (304.8 meters) above sea level, which formed the basis of the plot of the 1995 film The Englishman Who Went Up a Hill But Came Down a Mountain. In contrast, hillwalkers have tended to regard mountains as peaks 2,000 feet (610 m) above sea level: the Oxford English Dictionary also suggests a limit of 2,000 feet (610 m) and Whittow states "Some authorities regard eminences above 600 m (1,969 ft) as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least 2,000 feet or 610 meters high, while the official UK government's definition of a mountain is a summit of 600 meters (1,969 feet) or higher. Some definitions include a topographical prominence requirement, typically 100 feet (30.5 m) or 500 feet (152.4 m). In practice, mountains in Scotland are frequently referred to as "hills" no matter what their height, as reflected in names such as the Cuillin Hills and the Torridon Hills. In Wales, the distinction is more a term of land use and appearance and has nothing to do with height.
How do hills form?
Hills may form through geomorphic phenomena: faulting, erosion of larger landforms such as mountains and movement and deposition of sediment by glaciers (notably moraines and drumlins or by erosion exposing solid rock which then weathers down into a hill).

What is a hill?
Lesson Summary. A hill is a landform that is higher than the surrounding land and has a visible summit; they're like mountains, only shorter. Hills over 1,000 feet used to be considered mountains, but that has been rejected by some geologists in favor of 2,000 feet instead.
How High Is a Hill?
Up until about 50 years ago, hills that were at least 1,000-feet high were considered to be mountains. But geologists, scientists who study landforms and rocks, couldn't agree about the height, so in the United States, the 1,000 foot rule is no longer used.
Why are drumlins called swarms?
This is because of the way the glacier moved over the land when the drumlin was formed. Drumlins are usually found in large groups called swarms.
What is the highest point of a mountain?
A summit is the highest point of a mountain or hill. The water pushes up the frozen ground and forms a pingo. Geologists are the scientists that study landforms and rocks. Moelwyn Mawr is a mountain in Wales that is now called a hill because it is 9 inches too short to be a mountain .
What is the name of the scientist who studies landforms and rocks?
Geologists are the scientists that study landforms and rocks.
How are hills and mountains formed?
Hills and mountains are both formed in the same ways. Some hills are formed by erosion, which is when wind or water wear away tiny bits of rock and then deposit them in a pile somewhere else. Millions of years ago, when glaciers (large sheets of ice) covered the Earth, they created many hills and mountains by scraping up rocks as they moved along and then leaving them behind someplace else. When glaciers melted, the running water also created many hills through erosion. Sometimes hills are formed when rocks under the surface of the Earth move around and push up from under the ground.
How are mountains and hills different?
Have you ever wondered how mountains and hills are different? Both are landforms, or features on the surface of the Earth that were formed by nature. They're both higher up than the surrounding land, and both have a summit, which is their highest point. It sounds like they're very similar, but let's find out how they're different.
What is a hill?
In geography, a certain type of elevation of the relief that is not very high (generally not higher than 100 meters in height) is called a hill. They are also called lomas, motas, hillocks, mounds, alcoves, hills or hills, although the latter term is also used to refer to elevations of up to 3000 meters in height in some Latin American countries.

What is the Hill equation used for?
The Hill equation can be used to describe dose-response relationships, for example ion channel open-probability (P-open) vs. ligand concentration.
Why is the Hill equation important?
The Hill equation (for response) is important in the construction of dose-response curves .
What is the Hill coefficient?
The Hill coefficient,#N#n {displaystyle n}#N#or#N#n H {displaystyle n_ {H}}#N#, may describe cooperativity (or possibly other biochemical properties, depending on the context in which the Hill–Langmuir equation is being used). When appropriate, the value of the Hill coefficient describes the cooperativity of ligand binding in the following way: 1 n > 1 {displaystyle n>1}#N#. Positively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules increases. For example, the Hill coefficient of oxygen binding to haemoglobin (an example of positive cooperativity) falls within the range of 1.7–3.2. 2 n < 1 {displaystyle n<1}#N#. Negatively cooperative binding: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules decreases. 3 n = 1 {displaystyle n=1}#N#. Noncooperative (completely independent) binding: The affinity of the enzyme for a ligand molecule is not dependent on whether or not other ligand molecules are already bound. When n=1, we obtain a model that can be modeled by Michaelis–Menten kinetics, in which#N#K D = K A = K M {textstyle K_ {D}=K_ {A}=K_ {M}}#N#, the Michaelis–Menten constant.
What is the Hill plot?
A Hill plot, where the x-axis is the logarithm of the ligand concentration and the y-axis is the transformed receptor occupancy. X represents L and Y represents theta. The Hill plot is the rearrangement of the Hill–Langmuir Equation into a straight line.
What is the difference between Hill and Langmuir?
The distinction between the two Hill equations is whether they measure occupancy or response . The Hill–Langmuir equation reflects the occupancy of macromolecules: the fraction that is saturated or bound by the ligand. This equation is formally equivalent to the Langmuir isotherm. Conversely, the Hill equation proper reflects the cellular or tissue response to the ligand: the physiological output of the system, such as muscle contraction.
What is the horizontal axis of the Hill equation?
The horizontal axis is the concentration of the ligand. As the Hill coefficient is increased, the saturation curve becomes steeper. In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration.
When was the Hill Langmuir equation first used?
The Hill–Langmuir equation was originally formulated by Archibald Hill in 1910 to describe the sigmoidal O 2 binding curve of haemoglobin. The binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as cooperative binding ).

Historical significance
Many settlements were originally built on hills, either to avoid floods (particularly if they were near a large body of water), or for defense (since they offer a good view of the surrounding land and require would-be attackers to fight uphill), or to avoid densely forested areas. For example, Ancient Rome was built on seven hills, helping to protect it from invaders.
