A short answer is:
Graphite
A longer answer is:
There are many minerals that break along flat surfaces. Probably the one that you would be most familiar with is "graphite". Graphite is a mineral formed from carbon atoms and it is used to make up the lead in pencils.
Because of the structure of graphite, it tends to break cleanly in parallel, "flat" surfaces. It is not as evident in a pencil, because the piece of graphite is so small, but if you had a very large piece of graphite and broke it, you would see it break into flat flakes or plates.
This is cleavage, a very useful diagnostic property of minerals.
Why are you asking a question for a school worksheet? Oh well, the answer is cleavage.

Cleavage
cleavage
Minerals that do not have weak bonds along specific planes will tend to have a higher resistance to breakage and fracturing. This is because weak bonds along specific planes create areas of weakness where the mineral is more likely to break or split. Without these weak bonds, the mineral will have a more cohesive structure and be less prone to breaking.
The cleavage of a mineral is the characteristic manner in which it splits along crystallographic structural lines or planes. Cleavage alone is not sufficient to be able to identify a given mineral, but it is a solid clue which, when combined with a few other characteristics, will allow an investigator to identify a mineral. The notation of cleavage will eliminate some minerals and lead the way to being able to categorize a given mineral as something else. A link can be found below.
As ground-water it dissolves the calcium carbonate that is limestone's primary mineral, in its flow through the rock's joints, bedding-planes and faults.
Many but not all of them do, specifically that is how diamonds are traditionally cut for jewelry.mica separates into sheetshalite separates into cubesquartz does not have weakly bonded planes, so it fractures

A mineral's ability to split easily along planes of weakness, producing flat surfaces.

Non-foliated.
It is a type of igneous or sedimentary rock.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
The mineral would either cleave on planes of weakness, or fracture.
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
A mineral can have varying numbers of cleavage planes, areas where there exists an inclination to cleave when struck or force is applied.. Most mineral crystals exhibit a preferred cleavage in certain directions, but may have cleavage planes in other directions.

If they are in the air so the answer is no, because if planes fly at high altitude and at high speed. It makes it alot difficult to get planes shot down.
What kind of metamorphic rock has its mineral grains arranged in planes or bands
