Which type of latitude is the angle between the equatorial plane and a radial line connecting the center of the ellipsoid to a point on the earth’s surface?

• • Geographic latitude

• • Geodetic latitude

• • Magnetic latitude

• • Geocentric latitude

What is the purpose of using best-fitting ellipsoid models?

• • They influence the atmospheric conditions on the Earth's surface

• • To accurately depict the Earth's shape for geodetic calculations

• • To study the variations in climate patterns across different regions

• All of the above

Which type of latitude is the largest for the same point?

• • Geocentric latitude

• • Geodetic latitude

• • Reduced latitude

• All are equal

What is a normal section in Geodesy?

• • A plane curve created by intersecting a plane containing the normal to the ellipsoid with the surface of the ellipsoid.

• • The shortest distance between two points on ellipsoid

• • A section tangent to the earth's surface

• • A section perpendicular to the meridian and parallel of latitude at the points

Geodesics provide the most accurate way to calculate the shortest distance between two points on the Earth's surface.

• True

• False

There are two principal radii of curvature at any point on the surface of the ellipsoid. Each of these is a function of the geodetic latitude.

• True

• False

The radius of curvature in the prime vertical is always greater than its counterpart in the meridian direction.

• • 
    True

• • False

• • Anywhere except at equator

• • Anywhere except at pole.

At any equipotential surface, the gravity potential is ......

• constant

• variable

Because of the uneven distribution of masses in the Earth, the plumbline is always straight.

• True

• False

The squared mean radius of curvature is given by (a)
