Answer: Ok So although the subject matter of thematic maps is nearly infinite, cartographers use common techniques involving points, lines, and areal units to illustrate the structure of spatial distribution. Isarithmic maps use lines to connect points of equal value; these lines are called isopleths, or isolines. Hope this helps have a awesome day❤️

Answer:
D) 13.62 kg/L
Explanation:
This problem can be solved by a simple rule of three.
The problem states that Mercury has a dansy of 30 lbs/L, and asks what is the density in kg/L. We have to convert from lbs to kg.
Each lb has 0.454 kg? How many kg are there in 30 lbs?
So:
1 lb - 0.454kg
30 lb - x kg
This means that mercury's density in kg/L is 13.62, letter D. Letter A is also 13.62, however it is not in the unit asked.
