Ques:- Corrosion protection measures and its quality control
Asked In :-
Right Answer:
Corrosion protection measures include the use of coatings (such as paint or epoxy), cathodic protection (using sacrificial anodes or impressed current), and corrosion inhibitors. Quality control involves regular inspections, testing of coatings for adhesion and thickness, monitoring cathodic protection systems, and conducting corrosion assessments to ensure effectiveness and compliance with standards.
Ques:- Who invented the latitudes and longitudes and the grid system?
Asked In :-
Right Answer:
The concept of latitude and longitude was developed by the ancient Greeks, with significant contributions from Hipparchus and later improvements by Ptolemy. The grid system was further refined during the Age of Exploration by various cartographers.

Ques:- What are different types of map projections?
Asked In :-
Right Answer:
The different types of map projections include:

1. **Cylindrical Projections** - e.g., Mercator projection
2. **Conic Projections** - e.g., Albers equal-area projection
3. **Azimuthal Projections** - e.g., Stereographic projection
4. **Interrupted Projections** - e.g., Goode's homolosine projection
5. **Pseudo-cylindrical Projections** - e.g., Mollweide projection
6. **Equal-area Projections** - e.g., Lambert cylindrical equal-area projection
7. **Perspective Projections** - e.g., Orthographic projection
Ques:- Is there a country that is dark all day?
Asked In :-
Right Answer:
Yes, there are countries, particularly in the Arctic and Antarctic regions, that experience polar night, where it can be dark all day for extended periods during winter. Examples include Norway, Sweden, and parts of Alaska.
