Something as hard as a rock may break due to several factors, including the application of intense force or pressure that exceeds its structural integrity. Environmental factors like temperature fluctuations can cause thermal expansion and contraction, leading to cracks. Additionally, natural weathering processes, such as freeze-thaw cycles or chemical reactions, can weaken the rock over time, making it more susceptible to breaking.
The surface of a break in a rock is called a fault. It occurs when there is movement along the break, causing the rock to shift position. Faults can range in size and can be caused by tectonic forces, weathering, or other geological processes.
If a rock is hard to break, it likely indicates that it has high strength and durability. It could be made of a dense material or have a strong mineral composition. This characteristic suggests that it can withstand significant force or pressure without fracturing or crumbling easily.
Soft rock erodes faster than hard rock due to its lower density and compressive strength, making it more susceptible to weathering and erosion processes. Factors such as water infiltration, freeze-thaw cycles, and chemical weathering can break down soft rock more easily. Additionally, soft rock often has a higher porosity, allowing for greater water absorption, which further accelerates erosion. In contrast, hard rock is more resistant to these processes, resulting in slower erosion rates.

It is just the hard sort. Most hard rock was constructed by slow solidification of magma but some metamorphosed sedimentary and igneous rocks can also be considered to be 'hard rock'. And most igneous rocks except volcanic ejecta are hard. But to a geologist a hard rock usually means a slowly solidified magma in which minerals had time enough to form visible crystals.
Any form of mechanical weathering causes rock to break into smaller pieces. A landslide will definitely cause rock to break. Meteor impact, plant root growth, ice wedging, and the movement of animals will also cause weathering.

Water and freezing/cold weather can make rocks break. The water makes the rocks break when it goes into the rock cracks. When the weather gets cold/freezing the water expands and the rock breaks. Or with a really good hammer. LOL:P
dont be lazy and keep looking
you can crush it good or you can scratch it on something hard
a rock or falling off of something

Faulting is caused by stress in the rock layers, the stress can break and crack the rock causing a fault. There are two types of faults a normal fault and a reverse fault.
chalk is made from a chalk like rock. The reson why its hard is because it a rock and the reson why it break so easy is because of its weight and size

The fraction/break itself is a fault caused by tectonic plate movement.
