,3 ways the earth's shape can be mathematically defined - 🧠 ANSWER
✔✔sphere, ellipsoid, geoid
The only correct representation of the Earth's surface - 🧠 ANSWER
✔✔geoid
Equivalent projection + example - 🧠 ANSWER ✔✔allows for comparing the
surfaces of the Earth within the map, since the areas of the continents are
accurate
the shapes of the continents are distorted
ex. Mollweide or Gall-Peters
Conformal projection + example - 🧠 ANSWER ✔✔the angles between
positions are preserved so that ships can navigate from place to place and
know how far it is going to be from where they are
land area is distorted
, ex. Mercator
