Plateaus
A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. Plateaus can be formed by a variety of geological processes and can vary in size from small, isolated formations to vast, continent-spanning plateaus. They are important features in both geology and geography, and can have significant impacts on local ecosystems and human societies.
Formation of Plateaus
Plateaus can form through several different processes, including:
- Volcanic Activity: Some plateaus are formed by successive lava flows from volcanic eruptions, which gradually build up to create a flat, raised surface. The Deccan Plateau in India is an example of a volcanic plateau.
- Uplift and Erosion: Plateaus can also be formed by the uplift of land due to tectonic forces, followed by erosion by water and wind. The Colorado Plateau in the United States is an example of a plateau formed through this process.
- Deposition: Some plateaus are formed by the deposition of sedimentary rock layers over millions of years, which are then uplifted to create a flat, elevated surface. The Tibetan Plateau is an example of a plateau formed through this process.

- Rocks formed from the accumulation and compression of sediment over millions of years.
Study Tips
When studying plateaus, it can be helpful to explore specific examples of plateaus around the world and understand the geological and geographical factors that contributed to their formation. Additionally, consider the ecological and societal impacts of plateaus in different regions.

Nature of Science
The Practice of Science - A: Scientific inquiry is a multifaceted activity; The processes of science include the formulation of scientifically investigable questions, construction of investigations into those questions, the collection of appropriate data, the evaluation of the meaning of those data, and the communication of this evaluation. B: The processes of science frequently do not correspond to the traditional portrayal of ''the scientific method.'' C: Scientific argumentation is a necessary part of scientific inquiry and plays an important role in the generation and validation of scientific knowledge. D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Not only does science require creativity in its methods and processes, but also in its questions and explanations.
Define a problem based on a specific body of knowledge, for example: biology, chemistry, physics, and earth/space science, and do the following:
Use tools to gather, analyze, and interpret data (this includes the use of measurement in metric and other systems, and also the generation and interpretation of graphical representations of data, including data tables and graphs)
