The tendency of some minerals to break unevenly along curved or irregular surfaces is called cleavage. Cleavage is a property that describes how a mineral breaks when subjected to stress, and it is determined by the internal arrangement of atoms within the mineral's structure.
Minerals break in the main two ways cleavage and fracture. Cleavage is breaking in flat planes but fracture is more uneven even unpredictable. The hardest mineral to break would be the diamond, which is placed at a ten on Moh's hardness scale.
Cleavage in minerals refers to the way they break along specific planes due to their atomic structure. This affects their physical properties by influencing their shape, luster, and overall durability. Minerals with good cleavage break easily along these planes, resulting in smooth surfaces, while those with poor cleavage break unevenly.
Earth's surface is heated unevenly due to variations in solar radiation absorption caused by factors such as the angle of sunlight, albedo (reflectivity) of different surfaces, and distribution of land and water. These factors lead to differences in heating rates and result in uneven distribution of temperature across the surface of the Earth.
No, dirt is not a homogeneous mixture. It is a heterogeneous mixture composed of various materials such as sand, silt, clay, organic matter, and minerals, which are unevenly distributed throughout.
This is because the mineral sample is non-isotopic in structure. Not of equal strength in all directions. Mica and asbestos fibres would be extreme examples. But many ordinary crystals, being formed under uncontrolled conditions, will have natural defects.
Hematite
The difference between a mineral that has cleavage and one that has fracture is that cleavage is the tendency of some minerals to brake along flat surfaces and fracture is the tendency of some minerals to brake unevenly along curved or irregular surfaces.

Fracture. When it breaks apart cleanly, that is called Cleavage.

calcium
A rough or irregular surface reflects light unevenly, causing it to scatter in different directions. This can create a diffuse reflection where the light is not reflected uniformly, unlike a smooth and polished surface that provides a clear and regular reflection. Examples include frosted glass, textured walls, or rough metal surfaces.
diamonds
If the sun unevenly heats the minerals in a rock causing the rock to break, it is an example of physical weathering.
There are multiple reasons for the earth's surface to be heated unevenly. The flat surfaces, waters, mountains, and craters, are all different things that can cause the earth to be heated unevenly.
