How were pyramids built?

The Pyramids Of Giza

( The ancient pyramids of Egypt were built and constructed from 2630-2610 BC. There are 3 main pyramids out of more than 12, in Giza. The Pyramid of Menkaure, the Pyramid of Khafre and the Great Pyramid of Khufu. They were made, The pyramids were made out of limestone, granite, basalt, gypsum, and baked mud bricks. ) 

All of the tools and materials they used were natural resources. They got the main source known as limestone from quarries. They would put water underneath the brick, then they would push a stick through the middle. During this process, the stick expands because of the water causing the brick to split in half. Once the bricks split, there ready to be transported and then laid. Bricks are then pulled on a so-called sled and have water poured on the sand before them in order for the sled to be, able to move. Once moved these bricks were then placed down and formed into the strongest shape ( the triangle ) Egyptians has to be smart about this and actually also created a lot of our subjects today. They then sealed what was now a formed pyramid with limestone.
