I don’t know have a great day
The Inca culture was one of the most developed in pre-Columbian America. Among their achievements, was their architectural ability. Inca structures were made of stone that fit together, with extraordinary stability. The buildings have survived for centuries, with no use of mortar, in areas that are prone to earthquakes and volcanic activity.
The Inca also developed calendars based on astronomical observations. Astronomers understood equinoxes, solstices and zenith passages. Numerical information, particularly for administration, was stored in <em>quipu</em> strings.
In terms of art, Inca ceramics were highly advanced, although most of their silver and gold work was melted down by the Spaniards.
They were also advanced in medicine, performing skull surgeries successfully and with high survival rates.
To protect our country! I hope this helps :D!
The right order is Cartography -> Navigational Compass -> Photography -> Internet.
Cartography - The first examples of maps used in Cartography dates back to the human pre-history. The oldest recorded route was found in Anatolia and was dated 6100-6300 BC, showing buildings and a volcano.
Navigational Compass - The first known compass was made with Lodestone, a black magnetized iron ore, during the 12th century. Chinese, European and Arab mariners used a different mechanism to make the magnetic phenomenon possible, but eventually, the lodestone was used to magnetize a needle that was floated on a small piece of wood in a small container of water.
Photography - The modern photography was established during the 19th century and was only used in a consistent manner by geographers by the end of that century.
Internet - The most recent milestone was the internet that came after the development of electronic computers in the 1950s.
