This makes avery stable âsaltyâ water molecule.This property of water allows for the transport of nutrients vital to life in animals and plants.A drop of rainwater falling through the air dissolves atmospheric gases. When rain reaches the earth, itaffects the quality of the land, lakes and rivers.
Energy Use and the Internal Combustion Engine. The first gasoline-fueled, four-stroke cycle engine was built in Germany in 1876. In 1886, Carl Benz began the first commercial production of motor vehicles with internal combustion engines. By the 1890s, motor cars reached their modern stage of development.
Prior to the development of coal in the mid 19th century, nearly all energy used was renewable. Almost without a doubt the oldest known use of renewable energy, in the form of traditional biomass to fuel fires, dates from 790,000 years ago. Use of biomass for fire did not become commonplace until many hundreds of thousands of years later, sometime between 200,000 and 400,000 years ago.
