What is the world's longest mountain range?

The world's longest mountain range is the Andes, which stretches along the entire western coast of South America, spanning over 7,000 kilometers (4,300 miles). The Andes are also the highest mountain range outside of Asia, with many peaks exceeding 6,000 meters (20,000 feet) in elevation.

The Andes are a major feature of the South American continent, and have played a significant role in shaping its geography, ecology, and human history. The range is home to numerous unique ecosystems and species, including the Andean condor, the world's largest flying bird, and the spectacled bear, the only species of bear native to South America.

The Andes have been inhabited by human civilizations for thousands of years, including the Inca, who built a vast empire in the region before being conquered by the Spanish in the 16th century. Today, the Andes remain an important cultural and economic center for the countries of South America, providing valuable resources such as minerals, water, and fertile soil.

The longest mountain range on Earth is called the Mid-Ocean Ridge. It is a continuous chain of mountains that runs along the floor of all the world's oceans, except for the Arctic Ocean. The Mid-Ocean Ridge is about 40,389 miles long, and it is still growing. The Mid-Ocean Ridge is formed by the movement of the Earth's tectonic plates. As the plates move apart, magma rises up from the Earth's mantle and fills in the gap. This process creates new ocean floor, and it also pushes the mountains of the Mid-Ocean Ridge higher. The Mid-Ocean Ridge is an important part of the Earth's ecosystem. It provides a home for many different types of marine life, and it also helps to regulate the Earth's climate.
