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.
What else can I help you with?
What purpose does geologists test rocks and minerals?
Geologists test rocks and minerals to understand their composition, properties, and how they were formed. This information helps in identifying the type of rocks/minerals present in an area, interpreting geological processes, and even exploring for valuable resources, such as ores or fossil fuels.
Why are the minerals considered to be the building blocks of rocks?
By definition, rocks are composed of minerals. There is not a single rock that is not composed entirely of minerals. Rocks and minerals are essentially one in the same thing. However, not all rocks are made of just one mineral. The vast majority of rocks contain many different minerals. For example granite, a very common rock, consists of the minerals Quarts, Feldspar, Mica and Hornblende. Limestone, another common rock, consists of the minerals Calcite and Argonite. Marble, a derivative of Limestone, and a nonfoliated metamorphic rock, consists primarily of the minerals Calcite and Dolomite, and sometimes even a bit of Graphite, Iron Oxide, Garnet and Magnetite.
What parts make up a rock?
Rocks are composed of grains of minerals or other materials bound together. They typically consist of one or more minerals, organic material, or even glass. Rocks can also contain fossils, gemstones, or other inclusions.
What rocks don't contain minerals?
most rocks from what i know contain minerals especially sedimentary rocks. and don't all rocks eventually become sedimentary rocks so really don't they all contain minerals to some extent :) hope it helped (by the way i am only a gcse student)
Where can you find minerals?
Minerals can be found in rocks, soil, and natural formations in the Earth's crust. They can also be found in mines, quarries, and mineral deposits all around the world. Some minerals like salt can be found in oceans and seas.

How much are rocks and minerals?
The price of rocks and minerals can vary greatly depending on factors such as rarity, size, quality, and where they are being sold. Common rocks and minerals can be relatively inexpensive, while rare or high-quality specimens can be quite expensive, sometimes costing hundreds or even thousands of dollars. It's best to research specific types of rocks and minerals to get an idea of their price range.
How do you use rocks to find minerals?
You can use rocks to find minerals by conducting visual inspections, hardness tests, streak tests, and even chemical tests like acid testing. The presence of certain minerals in rocks can indicate the possible presence of valuable minerals nearby. Geologists also use rock formations and associations to predict the likelihood of finding specific minerals in a particular area.

What is the general shape of a mineral?
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.
Why do rocks move in different directions?
First of all, why would rocks move in different directions? Even though rocks could move in different directions, it is not possible for them to move on their own. Rocks have to have force applied to them in order to move.
Are minerals in different shapes?
even shapes diffrent area
What are the three tests for finding the three properties of rocks and minerals?
i dont know i dont even know how i got on this
Does weathering and erosion both break down into rocks and minerals?
Yes, actually it breaks down everything because water is the strongest force on earth... maybe even the universe and it can break anything down for two reasons the chemicals in it and the rubbing of it against other materials.
Where do you find minerals?
Any rock contains minerals. So does all food. If you are looking for minerals, rocks and mineral specimens, you can find them everywhere in nature.
