What's sedimentary rock?

An equal area map projection so the correct answer is AREA.

Is holographic picture of small area is same as photographic picture of that area?

Holography is a technique which enables three-dimensional images (holograms) to be made. It involves the use of a laser, interference, diffraction, light intensity recording and suitable illumination of the recording. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the image appear three-dimensional.

The holographic recording itself is not an image; it consists of an apparently random structure of either varying intensity, density or profile.

What exactly this holographic projection means ?

The Mollweide projection is a pseudocylindrical map projection generally used for global maps of the world (or sky).The projection was first published by mathematician and astronomer Karl (or Carl) Brandan Mollweide (1774 - 1825) of Leipzig in 1805. It was popularized by Jacques Babinet in 1857, giving it the name homalographic projection. The variation homolographic arose from frequent nineteenth century usage in star atlases.

MOLLWEIDE PROJECTION : HOMOLOGRAPHIC PROJECTION : BABINET PROJECTION is a pseudo cylindrical projection of the world in an approximate manner sacrificing accuracy of angle and shape to protect the accuracy of area.

Mollwiedi projection was first published by Kerl and Jonney in the year (1773 -1825)

A map projection reproducing the ratios of areas as they exist on the earth's surface.
