Answer:
Mercator projection
Explanation:
Using a flat paper map to represent the sphere that is our planet has always been a challenge. The Mercator projection is one of the most common representation, although we know it is more accurate around the Equator line and the precision diminishes as you get closer to the poles.
There are other types of projections, correcting some issues, but with their own flaws too. The only accurate representation of the planet is a globe, since it matches the shape of the planet.
Answer:
Yes, for example humans can make a triangle if they stack up on eachother and have good stability.

Answer:
Porosity
Explanation:
Porosity is defined as the total percentage of pore spaces that are present within a rock. These spaces are found between the rock particles and fractures and are mostly filled with fluid mixture or water. It is the ratio between the total pore space in a rock to the total volume of the rock. It is mainly calculated in terms of percentage.
Porosity is directly affected by sorting. Well-sorted rocks indicate high porosity but poorly-sorted rocks indicate low porosity. Some of the examples of rocks exhibiting high porosity are limestone, shale, and sandstone. Rocks with low porosity include granite and mudstone.
