Landforms
Plains, often characterized by their vast, relatively flat expanses of land, can be considered natural treasures due to a combination of factors:
-
Biodiversity Hotspots:
Plains can support a wide variety of plant and animal species. Grasslands, a type of plain, are known for their diverse flora, which in turn supports a variety of fauna, including grazing animals, birds, and insects.
-
Agricultural Significance:
The fertile soils of many plains make them ideal for agriculture. They are often the "breadbaskets" of regions and countries, providing essential food resources.
-
Carbon Sequestration:
Grasslands and other plains vegetation play a role in carbon sequestration, helping to mitigate climate change by storing carbon in the soil.
-
Water Resources:
Plains can act as important watersheds, collecting and filtering water that replenishes rivers, lakes, and underground aquifers.
-
Geological and Historical Significance:
Some plains hold geological importance, showcasing unique landforms or formations. Additionally, many plains have historical significance as sites of human settlement, migration, and cultural development.
It's important to note that the value of plains as natural treasures is increasingly recognized, leading to conservation efforts aimed at protecting their biodiversity, ecological functions, and cultural heritage.
A waterfall is a place where water flows over a vertical drop or a series of steep drops in the course of a stream or river. They are typically formed when a river flows over a resistant rock bed that erodes slowly, while the downstream rock is softer and erodes more quickly.
Here are some key characteristics of waterfalls:
- Formation: Waterfalls are often created when a layer of hard rock lies over a layer of softer rock. The softer rock erodes more quickly due to hydraulic action and abrasion, undermining the harder rock, which eventually collapses and creates the waterfall.
- Erosion: The force of the water falling over the edge erodes the plunge pool at the base of the waterfall. This erosion can cause the waterfall to retreat upstream over time.
- Types: Waterfalls come in various forms, including plunge, tiered, horsetail, and cascade waterfalls, each distinguished by the way the water descends.
- Ecological Importance: Waterfalls can create unique habitats for plants and animals.

A green area with water in the middle of a desert is called an oasis.
Oases are formed when a spring or other source of fresh water surfaces in a desert, allowing plants and animals to thrive and creating a habitable zone.
They are vital for supporting life in arid regions.
