A plateau is a flat or gently sloping elevated area of land that rises sharply above the surrounding terrain. It is often formed through volcanic activity, erosion, or the uplift of the Earth's crust. Plateaus can vary in size and can be found in various environments, including deserts, grasslands, and mountainous regions. Plateaus are significant in geography because they can influence climate and ecosystems. They often serve as natural barriers and can host unique wildlife and vegetation. Famous examples of plateaus include the Colorado Plateau in the United States and the Deccan Plateau in India.
