MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Which crystal system is characterized by three equal lengths and all angles measuring 90 degrees?
Isometric (Cubic)
Monoclinic
Tetragonal
Orthorhombic
Answer explanation
The isometric (cubic) crystal system is defined by three equal lengths and all angles measuring 90 degrees, making it the correct choice for this question.

In the tetragonal crystal system, how does it differ from the cubic system?
One dimension is lengthened
All sides are of different lengths
All angles are not 90 degrees
It has a hexagonal base
Answer explanation
In the tetragonal crystal system, one dimension is lengthened compared to the cubic system, where all sides are equal. This elongation creates a rectangular prism shape, distinguishing it from the cubic structure.

What is a key characteristic of the orthorhombic crystal system?
All sides are equal
It has a hexagonal base
All three dimensions are of different lengths
All angles are not 90 degrees
Answer explanation
The orthorhombic crystal system is characterized by having three axes of different lengths, which meet at right angles. This distinguishes it from other systems, making 'All three dimensions are of different lengths' the correct choice.

Which crystal system introduces a slight tilt to the cubic shape?
Triclinic
Rhombohedral (Trigonal)
Hexagonal
Monoclinic
Answer explanation
The rhombohedral (trigonal) crystal system introduces a slight tilt to the cubic shape, resulting in a distorted cube where the angles are not 90 degrees, distinguishing it from the perfect cubic structure.

In the monoclinic crystal system, what is the combination of shapes it contains?
Cubes and hexagons
Hexagons and rhomboids
Rectangles and rhomboids
Triangles and squares
Answer explanation
The monoclinic crystal system is characterized by having two axes of unequal lengths and one axis that is inclined. This results in shapes like rectangles and rhomboids, making 'Rectangles and rhomboids' the correct choice.

What distinguishes the triclinic crystal system from others?
It has a hexagonal base
All sides and angles are distinct
All angles are 90 degrees
It forms perfect cubes
Answer explanation
The triclinic crystal system is unique because it has no symmetry; all sides and angles are distinct, meaning they can vary in length and degree. This sets it apart from other systems, which often have equal sides or angles.

Which crystal system is easily recognizable by its hexagonal base?
Orthorhombic
Hexagonal
Tetragonal
Rhombohedral (Trigonal)
Answer explanation
The hexagonal crystal system is characterized by a hexagonal base, making it easily recognizable. Other systems like orthorhombic, tetragonal, and rhombohedral do not have this distinct hexagonal shape.
