What is the use of science and technology?

Science and technology help each other advance. Scientific knowledge is used to create new technologies. New technologies often allow scientists to explore nature in different ways and make new discoveries. Examples of technologies that have helped science advance include the telescope and microscope.

It’s a lot of useful things you use science and technology for . Science contributes to technology in many ways. One way is you can learn new knowledge which serves as a direct source of ideas for some new technological possibilities. The second way is it can be a source of tools and techniques for more efficient engineering design and a knowledge base for evaluation of feasibility of designs. One of the last things are research instrumentation.

People who live in "hot, dry climates" often rely on "desalination plants" for their drinking water.

Explanation:

The precipitation in hot and dry regions is next to negligible.The only source that the residents in this region can rely on for drinking water are the desalination plants. These plants are fed with waters from nearby bodies of water which are generally saline in nature. Solar energy is used to vaporize this water and the vapors are captured and condensed to form fresh water.
