Hills

The word “Hills” means plural of hill: raised areas of land, smaller than mountains. In plain terms, more than one hill — a stretch of raised, sloping land.

“Hills” is pronounced hihlz (/hɪlz/ in IPA).

Here is “Hills” used in a sentence: “They drove through rolling green hills for hours.”

“Hills” is a noun.

“Hills” is a fairly common word in modern English.

Both are raised areas of land, but hills are lower, gentler, and more rounded, while mountains are taller and steeper. There is no strict height that separates them, and the distinction is relative and varies by country. Generally, anything under about 600 metres is called a hill rather than a mountain.

Well-known hills include the Seven Hills of Rome, on which the ancient city was built, the Hollywood Hills in Los Angeles, and Britain's rolling Cotswold and Chiltern Hills. Ranges of low, grassy hills are often called downs or highlands, depending on the region and their character.

Hills form through several natural processes. Some are created when tectonic forces fold or uplift the Earth's crust; others are the worn-down remains of ancient mountains eroded over millions of years. Glaciers, faulting, and the build-up of sediment or volcanic material can also raise the smaller mounds we call hills.
