Explain The UAE`s landscape changed even more dramatically 100 million years ago.in that time, the UAE lay on the edge of what is called the Arabian plate. The plate began to move and came into the contact with the ocean floor. Often this collision results in the ocean floor being pushed under the land surface, but on this occasion the ocean was pushed on the top of the Arabian plate. Over the next 25 million years, more and more of the ocean floor was pushed upwards to form mountains. Eventually, these mountains emerged from the sea and today they form the rugged Al Hajar Mountains. 4- Why are time lines important in history?

The soil reacts with the dissolving bones forming new substance which has been produced over millions of years. The scientists that study fossils are called paleontologists.
