Best Answer

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).

I want you to think about your question. You learned in your science class about how water changes the land and things around it. So, since this is the case think about what it would do with a rock. Now, take that and answer your question. You KNOW the answer.

Why does rock tend to become rounded?

A lot of rocks have sat in water at one time or another, and flowing water erodes minerals, giving rocks a smooth, rounded shape over time.


Are there big nuggets of gold in rocks?

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.


Does erosion wear away rock and makes them square?

No. Although the movement of rocks may assist in their reduction in size, the weathering that occurs will tend to produce rounded edges.


What kind of rock is composed of rounded rock fragments?

A conglomerate, classified by rounded rock fragments larger than 2cm compacted and cemented into a rock.


How do the rock fragments formed by weathering become rounded grains?

Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains

When rocks are compressed do they fragment and become jagged or rounded?

They fragment and become jagged, they become rounded by means of water erosion, which is why rounded rocks are found by rivers, creeks, etc.


What is the grain shape of a rock such as conglomerate?

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.


Does granite have rounded grains?

Granite does not have rounded grains but contains interlocking grains. An example of a rock with rounded grains is a sandstone.
