Lakes
Definition
A lake is a large body of water that is surrounded by land and is not connected to the sea. Lakes can vary in size from small ponds to large bodies of water like the Great Lakes in North America.
Formation
Lakes are formed through various geological processes, such as glacial activity, volcanic activity, tectonic movements, or by the damming of rivers or streams.
Physical Characteristics
- Depth: Lakes can vary in depth, with some being shallow and others being very deep.
- Water Quality: The water in lakes can range from clear to murky, depending on factors such as sediment, algae, and pollution.
- Flora and Fauna: Lakes support a diverse range of plant and animal life, including fish, birds, and aquatic plants.
- Shoreline: Lakes have a shoreline that can vary in topography, including beaches, cliffs, and marshy areas.
Importance
Lakes play a crucial role in the environment and society, providing habitats for wildlife, sources of drinking water, recreational opportunities, and serving as important landmarks and cultural symbols.

Physical Science
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
Relate temperature to the average molecular kinetic energy.
