The form of energy associated with the position or arrangement of objects in a system. Second Law of Thermodynamics. States that no enrgy transformation is perfectly effiecients; in a closed system, some energy from every transformation will always be lost as heat, with a corresponding increase in entropy.
When we think of water, we think of rain, lakes and rivers. because they are parts of our daily lives. Water is also found in the atmosphere, underground, in. snow, ice, seas and oceans. It is in constant motion and recycles itself through the Water Cycle. Most of the earthâs water is salty or permanently frozen. 95.1% of water on earth is estimated. to be salt water. Fresh water total only 4.9% of all water on earth. Fresh water is found in. ice, lakes, rivers, streams and underground.
The dissolved salts carried by all the worldâs rivers would equal the salt in the ocean in about 200 to 300 million years. A second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the worldâs lakes are not? Lakes are temporary storage areas for water.
