Hills can be made by nature. Wind and water can wear down mountains to make them. Ice can also move dirt to shape a hill.

People use hills for many things. Long ago, people built towns on hills. This helped them stay safe from floods. It also helped them see enemies coming.

Some people in Scotland call big mountains "hills." It can be hard to tell them apart.

Nature makes hills in many ways. Wind and water can wear down mountains. This can leave a hill behind. Glaciers, which are huge sheets of ice, can also move dirt to make hills. One type is a drumlin. This is a hill shaped like a whale.

It usually has a distinct summit at the top. Most people think of hills as being smaller than mountains. They are often less tall and less steep.

However, the line between a hill and a mountain is not always clear. It can be quite subjective. In Scotland, people often call big mountains "hills."

For example, they use names like the Cuillin Hills for mountain areas. In Wales, the names depend more on how the land looks. This shows that how we name things can change based on where we live.

Nature has many ways to create these landforms.

Sometimes, hills form when the earth cracks or shifts, which is called faulting. Other times, they come from the erosion of much larger mountains. Wind and water can wear down rock until a hill remains. Glaciers can also move dirt to build hills. One type is a drumlin, which is a hill shaped like a whale.

Another kind is a pingo, which is a mound of earth with ice inside. Even the soil itself moves slowly downhill. This slow movement is called downhill creep and helps make peaks look rounded.

People have used hills for many important reasons throughout history. Many old settlements were built on high ground to avoid floods. Being on a hill also helped people defend their homes. It is easier to see enemies coming from a high spot. It is also hard for attackers to fight while moving uphill.

Ancient Rome was famously built on seven hills to help protect it. In the Middle East, some people live on "tells." These are artificial hills made from old mudbricks and debris.

These hills show how people lived in the same places for many generations.

Because hills offer a great view, they have been important in many battles.

Controlling the high ground gives an army a better place to fire. It also lets soldiers hide behind the crest of the hill. The Battle of Alesia happened in 52 BC. The Battle of Mons Graupius in AD 83 was the first recorded conflict in Scotland. In 1775, the Battle of Bunker Hill took place in America.

During the American Civil War in 1863, battles happened at Cemetery Hill. Later, the Battle of San Juan Hill occurred in 1898. These events show how much the shape of the land matters in war.

Today, hills are still a big part of how we live and play.

Many people enjoy hillwalking, which is a type of hiking. In Britain, people often try to climb hills on special lists. They might try "Munro bagging" to climb every hill on a list. Some people even have fun races on hills. In England, people roll wheels of cheese down hills at Cooper's Hill.

Others use hills for sports like golf or cross-country running. Whether they are natural or man-made, hills are a constant part of our world.

A hill is a landform that rises above the surrounding terrain.

It usually features a distinct summit, which is the highest point of the landform. Geographically, hills are classified as slope landforms. While they are part of the same family of shapes as mountains, they are generally less prominent. This means they are usually not as tall or as steep as mountain peaks.

Because of this, hills are essential features of the Earth's surface, influencing how we live and move.

The distinction between a hill and a mountain is often subjective. There is no single, universal rule to separate them. Historically, some geographers viewed mountains as hills that rose above sea level. In contrast, many hillwalkers define mountains as peaks that sit above sea level. In the United Kingdom and Ireland, a mountain is often defined as any summit reaching at least 600 meters.

Different regions also use different rules. For example, the United States once defined a mountain as being 1,000 feet or more in height. However, the United States Geological Survey later concluded that these terms lack technical definitions in the U.S. In Scotland, people often call large mountains "hills" in local names, such as the Cuillin Hills.

Natural processes create hills through various geomorphic phenomena. One method is faulting, where the Earth's crust shifts or cracks. Another method involves the erosion of larger landforms like mountains. Over time, wind and water wear down rock until only a hill remains. Glaciers also play a role by moving and depositing sediment.

This movement can create specific shapes like moraines or drumlins. Furthermore, the rounded appearance of many hills comes from downhill creep. This is the diffusive movement of soil and regolith, which is the layer of loose material covering solid rock. This slow movement gradually smooths out the landscape.

Geologists use many specific names to describe different types of hills. A drumlin is an elongated, whale-shaped hill formed by glacial action.

A butte is an isolated hill with steep sides and a small, flat top, created by weathering. In Central Europe, a rounded hill or low mountain is called a kuppe. In the Arctic and Antarctica, a pingo is a mound of earth that covers a core of ice. Other regional terms include the Scots word "brae" for a hillside. In South West England, a rock formation on a hilltop is often called a tor. These names help scientists and locals describe the unique shapes of the land.

Throughout history, humans have settled on hills for practical reasons. Many ancient settlements were built on high ground to avoid flooding near water. Hills also provided defense because they offer a clear view of the surroundings. Attackers are forced to fight uphill, which is much more difficult.

Ancient Rome is a famous example, as it was built on seven hills to protect against invaders. In the Middle East, some settlements are actually "tells." A tell is an artificial hill made of accumulated debris and mudbricks from many generations of living.

These hills represent the physical history of human habitation.

Because of their strategic value, hills have been central to many military conflicts. Controlling the high ground provides an army with an elevated firing position. It also allows soldiers to hide behind the crest of the hill for cover.

Notable battles have occurred on hills, such as the Battle of Alesia in 52 BC and the Battle of Mons Graupius in AD 83. In the American War of Independence, the Battle of Bunker Hill took place in 1775. During the American Civil War in 1863, Cemetery Hill and Culp's Hill were key sites. More modern conflicts, like the 1969 Battle of Hamburger Hill during the Vietnam War, also highlight the importance of these landforms.

Today, hills remain important for recreation and culture. Hillwalking is a popular activity in Britain, involving the ascent of hills without technical climbing gear.

Some enthusiasts participate in "peak bagging," which means trying to climb every hill on a specific list. In England, the annual Cooper's Hill Cheese-Rolling and Wake involves people chasing a wheel of cheese down a slope.

Hills also shape our landscapes for agriculture, such as the famous vineyards in Italy.
