This is a doubt that even native English speakers have!
Electric and electrical are essentially the same - they refer to any device that uses electricity. Flashlights are electric; we also have electric lights and electric heaters, and nowadays even electric cars. Something that is electric just uses electricity for energy.
Something that is electronic is a more complex system - it manipulates the electrical energy in ways that allow for more advanced functions, such as
transmitting information. Computers are electronic, and we also use electronic for digital versions of things in the physical world, like electronic stores/books.
The strange and weirdly beautiful terraced pools of Pamukkale have been appreciated for over two millennia and yet still remain a little known wonder of the world. Thousands of years ago earthquakes, which are common in Turkey, created fractures that allowed powerful hot springs to bring water rich in calcium carbonate to the surface. As the water evaporated the chalky material condensed and formed layer-upon-layer of Travertine and thus slowly built up the walls over time in the same way that a stalactite forms in a cave. Apparently Pammakale means Castle of Cotton but the Greco-Romans built a town above it called Heirapolis ? meaning Holy City or Sacred City. They too recognised it as a rare and important place attributing healing powers to the milky-white waters.
