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.
Its surface and shores are 429 metres (1,407 ft) below sea level, Earth's lowest elevation on land. The Dead Sea is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With 34.2% salinity (in 2011), it is 9.6 times as salty as the ocean, and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea is 50 kilometres (31 mi) long and 15 kilometres (9 mi) wide at its widest point.
