Because Egyptians believed that this life is just one phase that lead to the one that starts after we die. That is why pharaohs and important persons were mummified so their body would be preserved to continue the road. They were put in pyramids, because they were built to be their tombs.
Explanation:
Process of mummification was a complex process which usually lasted for 17 days. Everything had to be well-planned and people who were involved in this process were to be very careful.

Not quite sure what you're asking, but erosion and deposition do create land forms. For example: erosion along the coastline may result in the formations of arches, stacks, stumps, wave cut platforms, caves, etc. Deposition, different amount of it and in certain areas, under the influence of either destructive or constructive waves, will form beaches - ones with a lot of beach, through a lot of deposition, or slopes beaches where destructive waves have crashed upon the beach. Hope this is what you're looking for.
