Rocks tend to become rounded through a process called weathering and erosion. As rocks are exposed to elements like wind, water, and ice, they undergo physical and chemical breakdown, which smooths their edges and corners over time. This gradual process often occurs in riverbeds or coastal areas, where constant movement and abrasion contribute to the rounding of the rock surfaces. Ultimately, the continuous movement and impact from surrounding materials help shape rocks into more rounded forms.
Its actually more about the composition of the rock than the shape, the rounded rocks tend to be of a softer material such as sandstone, limestone etc which erode quicker and as such form into rounded shapes were harder rocks such as granite are more resistant to erosion and therefore its the softer materials that erode and leave the sharp edges of granite.
Erosion can wear away rock pieces, but it is unlikely to make them square. Erosion typically smoothens and rounds the edges of rock pieces as they are transported by water, wind, or ice. Square-shaped rocks are more likely to result from natural fracturing or human activities like quarrying.
No, harder rocks generally erode more slowly than softer rocks because they are more resistant to weathering and abrasion. Soft rocks tend to be more easily worn away by wind, water, and other environmental factors.
Volcanoes tend to form where plates collide. They are the mechanisms by which magma reaches the surface of the Earth; magma may also flow to Earth's surface between the moving plates at a divergent boundary. Called lava on Earth's surface, it cools and forms igneous rock. Igneous rock is a type of rock in the rock cycle. Through weathering, igneous rocks can become sediment, which eventually can become sedimentary rock. This sedimentary rock, or the original igneous rock, can also become metamorphic rock when exposed to heat and pressure beneath Earth's surface. Metamorphic rocks in turn melt and become magma. This magma plus additional magma from theEarth's interior begin the cycle again.
Rocks tend to become rounded due to the processes of erosion and weathering. As rocks are exposed to elements like water, wind, and ice, they gradually break down and wear away, causing their edges and corners to smoothen over time. This results in a more rounded shape for the rock.
A nugget is gold that has weathered out of rock. Resistant to weathering, but malleable, the gold weathered from rock will tend to become rounded, taking the shape of a nugget. Although gold can be found in association with existing rock in situ, it will not have the characteristic rounded shape of a nugget.

Weathering, which is breaking of rock into smaller pieces, works to round exposed edges of rock by chemical weathering from naturally acidic rainfall and through physical weathering such as particle abrasion and rock tumbling due to the transport of material by wind, water, ice, and gravity (erosion).
No. Although the movement of rocks may assist in their reduction in size, the weathering that occurs will tend to produce rounded edges.

The angular grains are probably due to the high feldspar content of the arkose rock. Unweathered feldspar from granite, the source rock of arkose, would be composed of crystals with sharply defined cleavage planes, and would have formed a more euhedral crystal shape compared to the rounded quartz grains that are present in quartz sandstones.
Conglomerate is one of two similar rocks not to be confused. The large 'grains' are rounded as a result of their formation, and indeed the formation of the rock. Conglomerate is not to be confused with Breccia, a similar rock formed in very different circumstances. Breccia fragments tend to be smaller, but most of all are always angular.

Hills tend to be more rounded in humid climates because of the higher levels of precipitation and vegetation. The constant moist conditions lead to chemical weathering processes that break down rocks more easily, resulting in smoother, more rounded hill shapes over time. Additionally, the presence of more vegetation in humid climates helps to further soften and shape the landscape, contributing to the rounded appearance of hills.
When people get older, they tend to get gray hair - that's the "crown of snow". And as people get older many(but not all) tend to become wiser. More experiences to draw from, more patience to think things through etc. It's a poetic but roundabout way of saying that people generally become wiser as they get older.
