A skyscraper is a very tall building that reaches high into the sky, often with many floors. These impressive structures are usually found in big cities like New York or Tokyo and are made of strong materials like steel and glass. Skyscrapers are designed to maximize space in crowded urban areas, allowing more people and businesses to occupy a smaller footprint. Many skyscrapers have unique designs and can be seen as symbols of a city's growth and innovation. Famous examples include the Burj Khalifa in Dubai, which is currently the tallest building in the world, and the Empire State Building in New York City, known for its iconic Art Deco style.
