Explanation / Answer

23. A Cubic

Halite is of cubic crystal system and are basically white to colourless in colour, sometime it may be different in colour depending upon the impurities present, and chemical formula is NaCl

24.B

Ocean trenches are long, narrow depressions on the seafloor. and at various convergent boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, eventually creating a trench

25. A

The Hawaiian was formed by a hot spot occurring in the middle of the Pacific Plate.

26.A

element is defined by the number of protons present in the nucleus of the atom.
