Babylonia, or Babylon, as some people call it, was a very small city in Southern Mesopotamia, which stood alongside other cities from the earlier Akkadian Empire, like Ur, Kish and Uruk, just to name a few. Around 1894 BC, however, it was a group called the Amorites, who took control of the city and began to organize it. Exactly in 1894, a dynasty from the Amorites formed a small kingdom called Kazallu, which would later on start to expand and change as subsequent Amorite rules took over control. Babylonia was the center of this small kingdom. There were many rulers who consistently helped Babylonia to develop and grow into an independent nation. The first such ruler, not yet named king, was Sumu-abum, followed by several others, until the first Amorite who called himself king: Sin-Muballit. It was in 1792 BC, that things changed in Babylonia, and it became a pretty powerful, but short-lived empire, under the rule of Amorite leader and king Hammurabi. It was this man who was responsible for the development and growth of the Babylonian Empire and its extension throughout most of Mesopotamia, alongside the much older Assyrian Empire.
Each isotope has a characteristic half-life, which is the time required for half of that isotope to decay. After one half-life has elapsed, 50% of the isotope has decayed and 50% remains. After two half-lives, 75% has decayed and 25% remains. After three half-lives, 87.5% has decayed and 12.5% remains. For carbon-14, which has a half-life of 5,730 years, three half-lives corresponds to 17,190 years.
The one on the top and right is water erosion, The one on the left is caused from a rock being there for so long is starts to become thinner because of the wind. Now the middle left is a natural basin that looks like water flowed through it so again water erosion. The middle right looks like the rocks and dirt fell off a mountain from being loosened from all the water,wind,humans and others so the kind of erosion is accelerated erosion. the bottom left is strong wind erosion. and the bottom right is a landslide. Hope this helps.
