Answer:
Because periods of economic growth are often triggered by increases in aggregate demand, such as a rise in consumer spending, but sustained growth must involve an increase in output. If output does not increase, any extra demand will push up the price level. To prevent inflation in economy, we need sustainable economic growth. Sustainable economic growth means a rate of growth which can be maintained without creating other significant economic problems, especially for future generations.
In biological terms, this effect would be<u> "diffusion".</u>
Diffusion is a spontaneous movement of particles from a territory of high focus to a zone of low fixation. (ex. tea seasoning moving from a zone of high to low fixation in heated water.)
Diffusion predominantly happens in gaseous state or inside gas atoms and fluid molecules.(e.g. The particles of 2 gases are in steady movement and if the layer isolating them is evacuated the gases will blend due to arbitrary speeds.)
the answer is because many of the concepts and ideas in theories are not directly observable.
For example, one of the most important theories that try to explain the formation of the universe is the Big Bang theory.
But, since this theory stated that the event happened million years ago, we couldn't make a possible effort to observe it and prove it's accuracy.
<u>"Water cycle"</u> has three stages - evaporation, condensation, and precipitation.
The water cycle portrays how water evaporates from the surface of the earth, ascends into the climate, cools and condenses into rain or snow in mists, and falls again to the surface as precipitation. The water falling ashore gathers in streams and lakes, soil, and permeable layers of rock, and a lot of it streams once more into the seas, where it will afresh dissipate. The cycling of water all through the air is a noteworthy part of the climate designs on Earth.
