Canyons
A canyon is a deep, narrow valley with steep sides that is often formed by the erosion of a river or by the movement of tectonic plates. Canyons can be found all over the world and are often known for their striking beauty and unique geological features.
Formation of Canyons
There are several ways in which canyons can be formed:
- River Erosion: Many canyons are formed by the erosive force of rivers cutting through the Earth's surface over millions of years. The flowing water gradually wears away the rock, carving out a deep and narrow valley.
- Tectonic Activity: Some canyons are formed by the movement of tectonic plates, which can create deep fissures in the Earth's crust. This movement can lead to the formation of rift valleys and other types of canyons.
- Glacial Activity: In regions where glaciers have been present, canyons known as "glacial troughs" can be formed by the movement of ice carving out deep valleys.
Study Guide
To understand canyons better, it is important to study the following key concepts:
- Geological Processes: Explore the different geological processes that can lead to the formation of canyons, including erosion, tectonic activity, and glacial activity.
- Landform Features: Study the unique features of canyons, such as their steep walls, narrow width, and the presence of rock formations like hoodoos and buttes.
- Case Studies: Examine specific canyons around the world, such as the Grand Canyon in the United States, the Fish River Canyon in Namibia, or the Tara River Canyon in Montenegro.
- Environmental Impact: Consider the environmental significance of canyons and their ecosystems, as well as the impact of human activities on these fragile landscapes.
- Recreational Use: Explore how canyons are used for recreational activities such as hiking, rock climbing, and river rafting, and the importance of preserving these natural spaces for future generations.
By studying these aspects of canyons, you can gain a deeper understanding of the geological forces that shape our planet and the importance of preserving these natural wonders for scientific, recreational, and environmental purposes.

Energy
Students who demonstrate understanding can:
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
