Content Summary :
We live on Planet Earth. Evidence reports that the Earth formed about 4.6 billion years ago. At that time, Earth was very hot, no wind blew, there was no water on its surface, and there were no living things. With the passing of billions of years, we have the Earth as we know it today. A Scottish geologist, James Hutton, developed the principle of uniformitarianism. This principle proposes that the processes that change the Earth today have been occurring for billions of years. These processes continue to occur. These processes include uplift (mountain building) and wearing down (weathering, erosion, and deposition).
