There is no general shape of a mineral. Each mineral has its own shape, even though two different minerals might have the same shape. A few examples of shapes of minerals are: Rhomboid, rock, and cubic.
Sounds like a rectangular solid to me, such as an elongated box.
A rhombus is a four sided polygon, a quadrilateral. It is a 2d shape. 2d shapes have 2 dimensions, like length and width. 3d shapes have 3 dimensions, like length, width and depth.
two and the shape is like a ladder
Brazil is particularly rich in several minerals, but two of the most well known minerals produced by mines like the minas gerais are Amythest (purple quartz) and Emerald (green beryl).
The two rocks in question may have different percentages of the same minerals, or their method of formation could be different, which can affect the shape and size of the mineral grains. Trace minerals in the two rocks could also alter their appearance, as well as the amount of weathering the rocks have been exposed to.
Wrenches come two ways, open ended and box end. Open end are just a U shape on the end. Box end go around the nut or bolt. If you were to slice a quarter inch off of a socket that is what the end of the wrench would look like.
A prism has two parallel and congruent bases in the shape of polygons. Example - a cereal box (is rectangular prism). The top and bottom are rectangles(a polygon). They are the same size and shape (congruent) and also parallel. A cube (think of six sided dice) is a special rectangular prism. Imagine a a box where the top and bottom are triangles (of the shape size and shape). This is called a triangular prism.
No. There are elemental minerals, like gold, silver, and copper, appearing in crystalline form. The bulk of minerals, however, are compounds of two or more elements.
what are the two major groups of minerals
Most cheese these days is sold in rectangular slabs, more or less similar to the standard box shape. Any other shape of box is awkward to make,doesn't stack well, and wastes space in transport. So, far from being "cool", this would actually be a ridiculously dumb move on at least two counts.
