planícies

Planícies are large areas of flat or gently rolling land with very little change in elevation. They are typically found at low altitudes, often near coastlines or major river systems. Their formation can be attributed to various geological processes, including erosion by rivers, deposition of sediment over long periods, or the gradual uplift or subsidence of the Earth's crust.

These landforms are characterized by their vast, open expanses and are often highly fertile due to the accumulation of rich soils, making them ideal for agriculture. Many of the world's major river valleys and deltas form extensive plains. Examples include the Great Plains of North America, the Indo-Gangetic Plain in Asia, and the Amazon Basin in South America.

The climate of plains can vary significantly depending on their geographical location, ranging from temperate to tropical or arid. Due to their flatness, plains often experience strong winds. Their accessibility and suitability for development have led to a high concentration of human population and infrastructure in many plain regions. While they offer many advantages, plains can also be susceptible to flooding, particularly those located near rivers or coastlines.
