Here are some milestones in the development of technology used by geographers. Put them in the order in which they appeared in history

1. Cartography

2. Navigational compass

3.Photography

4. Internet

Explanation:

Cartography: is a method of designing, creating and studying geographic locations on flat surfaces like maps. This scientific method dates to some thousands of years ago. It dates to pre-historic times as far back as 2300 BCE when the Babylonians represented locations in clay tablets.

Internet: the inventions of computers in the 1950's came along with the internet that has been a useful resource for geographers.

loess contribute to the flooding of rivers by providing the silt that is washed into rivers and constantly raises the bed of the rivers. this elevation above the surrounding flood plains and dams allow the river to overwhelm the dams and flood thousand of square miles of neighboring flood plains.
