What is the difference between the cloud model of the atom and the modern model?

Bohr's model treats electron energy levels as clearly defined orbital paths around the nucleus like planets orbit the Sun. The cloud model treats the energy levels as probability clouds, regions in which electrons are likely to be found.

When we are able to repeat a process indefinitely without using up or contaminating the resources, it is known as Renewable Resources .
Explanation:
Renewable resources are the naturally available resources which will replenish to replace the portion of depleted usage and consumption by natural reproduction.One of type of renewable resource is renewable energy including solar, geothermal and wind energy.
These renewable resources are very important part of Earth's natural environment. Water also form a part of renewable source. Water, if carefully used and controlled it's usage in daily life and also given proper treatment then the water is considered as renewable resource
