As a substance is broken, the surface area greatly increases. For example a 2 meter cube has a total surface area of 24 square meters. If a 1 meter cube is cut out of one corner, the total surface area is now 30 square meters.

Why is it helpful to have rocks broken into smaller and smaller pieces?

It is helpful because it increases surface area available for the chemical weathering process.


What are the ways where diamond can be broken to smaller pieces?

Best practices dictate that if you want any control whatsoever over the size and geometry of the smaller pieces, that you take your diamond to a diamond cutter and pay to have it 'broken' into smaller pieces. If you don't care about the smaller pieces, or the value of the diamond, you could hit the diamond with a hammer and see what happens.


Why are charcoal pieces often broken up into smaller pieces before they are used in barbecue pits?

They provide a greater surface area to burn therefore giving more heat.


If we put pressure on ice then how can it melt?

Putting pressure on ice can melt it by helping to break it up into smaller pieces, as happens when ice is crushed. Smaller pieces have greater surface area that can be exposed to warmer air.

What is the relationship between surface area and weathering rate?

The rate of weathering also depends on the surface area that is exposed. Mechanical weathering breaks rocks into smaller pieces. As the pieces get smaller, their surface area increases. When this happens, there is more total surface area available for chemical weathering. The result is that weathering has more of an effort on smaller particles.
