Geologists are not primarily map makers, but they often use maps as important tools in their work. Geologists study the Earth's structure, composition, and history, which may involve creating maps to visualize and communicate their findings. Geographic information systems (GIS) are commonly used by geologists to help create detailed geological maps.
Two disadvantages of geodesy maps are limited detail in terms of topographic features compared to other specialized maps like topographic maps, and potential distortions in size and shape of features due to the projection used in creating the map.
Yes, that's correct. When you try to flatten a spherical surface like the Earth onto a 2D map, distortions are inevitable due to the inherent differences in geometry. Different map projections exist to minimize these distortions, but no single projection can accurately represent all aspects of Earth's surface simultaneously.
A map is a diagram illustrating and therefore communicating some aspect of reality. Therefore a geographer will chose the map form that is most appropriate for the subject to be communicated. For instance a map of the world could show countries in proportion to their true area. Or the size of the countries could be scaled in proportion to their population. Also when making a flat map of a sphere (the globe of the Earth) it is impossible to "flatten" the surface without causing tears or distortions. All flat maps are therefore projections which contain distortions. Geographers will choose a projection which does not distort the aspect they are trying to show.
Distortions in maps occur due to the challenge of representing a 3D spherical surface on a 2D flat plane. This distortion can manifest in various ways, such as in shape, size, distance, or direction. Different map projections aim to minimize specific types of distortions depending on the intended use of the map.
A map can be distorted by shapes, sizes, lines of latitude and longitude.
it i s show makeras
Distortions on a map occur because it is impossible to accurately represent the three-dimensional surface of the Earth on a flat plane. Different map projections prioritize different aspects, so distortions in shape, distance, area, or direction can occur when maps are created. The choice of projection depends on the purpose of the map and the area being depicted.
There always distortions on a map because a map is flat and a globe is round.

Shading and contour lines are an attempt by the map makers to show the terrain covered by the map.
