It is false that the mathematical system in Mesopotamia was based on the number 7. O.
<u>Explanation:</u>
The mathematical system is Mesopotamia was based on the number 60 at it's base and not on 7. This numeral system is known as sexagesimal which had 60 at it's base.
This originated in the 3rd millennium BC and passed on to the ancient Babylonians and it is still used for measuring angles, times, geographic co ordinates. Since the statement that the mathematical system in Mesopotamia was based on number 7 is incorrect.
Answer:
Hover for more information. Humans can affect weathering (breaking down of rock/soil) in several ways. Humans cause increases in acid rain and pollution, which increase the amount of weathering agents in the air and water, and then on land The effects of weathering disintegrate and alter mineral and rocks near or at the earth's surface. This shapes the earth's surface through such processes as wind and rain erosion or cracks caused by freezing and thawing. Each process has a distinct effect on rocks and minerals.

The entire United States and the rest of the world serve as the hinterland for all of the following cities except Tucson.
V shaped contour line pointing downhill indicate a ridge line, while the ones pointing uphill indicate a water flow.
Explanation:
The contour lines are one of the basic and most important elements on the maps. While in general they are associated with representing the elevation, they actually tell much more about the topography of a place. In a typical contour line, it is relatively common that the V shape occurs at particular places.
The V shape can be pointed downhill or uphill. The ones that point downhill are indicators of a ridge line, thus they show us the ridge more easily, so we can orientate better and have better representation of the area. The ones that point uphill, on the other hand, are indicators that there is a water flow, or there was a water flow. The rivers and streams with their erosive power manage to create such shapes in the relief, if viewed from above. The opening on the V is from where the water flows down.
Some of the types of contour lines are:
- isopleths
- isohyets
- isobars
- isobaths
- isoterms
- isonephs
