Waterfalls
A waterfall is a natural phenomenon where water flows over a vertical drop or a series of drops in the course of a stream or river. They are formed as a result of erosion and are often found in mountainous or rugged terrain.
Formation of Waterfalls
Waterfalls are typically formed in the following ways:
- Erosion: The force of the water gradually erodes the rock and soil beneath it, creating a vertical drop.
- Geological Faults: Sometimes, geological faults or fractures in the Earth's crust can lead to the formation of waterfalls.
- Differential Erosion: Softer rock layers erode more quickly than harder layers, leading to the formation of a waterfall.
Key Features of Waterfalls
Waterfalls have several distinctive features, including:
- Plunge Pool: The basin at the foot of the waterfall, formed by the erosive force of the falling water.
- Cascade: A series of small waterfalls that occur along the course of a river or stream.
- Veil: A type of waterfall where the water descends in a wide sheet.
Study Guide
Here are some key points to focus on when studying waterfalls:
- Understand the geological processes that lead to the formation of waterfalls.
- Learn about the different types of waterfalls and their unique characteristics.
- Explore the role of waterfalls in the ecosystem and their significance in the environment.
- Examine the impact of human activity on waterfalls and their conservation.
Remember to also study examples of famous waterfalls around the world, such as Niagara Falls, Victoria Falls, and Angel Falls, and understand their unique geological and geographical features.
By studying these aspects, you'll gain a comprehensive understanding of waterfalls and their significance in the natural world.

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).
