The true representative model of our Earth is :

Concept: A true representative model of the Earth must reproduce its actual three-dimensional shape and preserve shape, area, distance, and direction all at the same time. Because the Earth's surface is curved, transferring it onto a flat surface (as in a map) always introduces distortion in at least one of these properties — this is the fundamental limitation of every map projection.

Application: Among the given options, the one that avoids this flattening distortion is the one built as a scaled-down three-dimensional sphere:

• Map: a two-dimensional drawing of the Earth's surface on a flat sheet, produced using a projection system; since a curved surface cannot be flattened without distortion, a map cannot preserve shape, area, distance, and direction simultaneously.

• Satellite image: a photograph of a portion of the Earth's surface captured by an orbiting sensor at one moment and viewing angle; it shows only part of the surface and is not a scaled geometric model of the whole planet.

• Rugby ball: a prolate spheroid, elongated with pointed ends — a shape that does not match the Earth's actual near-spherical form.

• Globe: a miniature three-dimensional sphere built to scale, so it reproduces the Earth's shape, proportions, and directions without the flattening distortion of a flat map.

Cross-check: NCERT Class 6 Geography states that a globe is regarded as the true model of the Earth because, unlike any flat map projection, it can maintain correct shape, size, distance, and direction all together. The CTET 2024 official answer key also lists Globe as the correct response. Hence, Globe is the correct answer.
