grains of sand will stick together when wet because of the property of water known as cohesion. cohesion occurs because the water molecule will become attracted to the sand because water will become polarized

Are bricks made from rock?
No, bricks are made out of clay which is fired at high temperatures in an oven or kiln. Clay itself was formed when rocks were weathered, releasing fine particles of minerals, usually silica (sand is made of silica and so is glass). When clay is wet these particles are separate but when it dries the particles stick together. Very high temperatures cause a chemical change in the minerals which cause them to harden (the same happens to sand which becomes liquid glass when heated and then hardens)
Why is water particles smaller than pieces of sand?
Because You Cannot See All The Particles In Water.. In Sand You Can See Them. Example: You CAN See A Grain Of Sand. SOURCES: Brain, School, Life,
How does the movement of particles in a stick of butter differ from the movement of particle in a dish of melted butter?
The movement of particles in a hard stick of butter are solid. Their not moving. While the movement of particles in a melted sick of butter are liquid. They are moving.
Why is it more exhausting to run on sand than on concret?
In sand the particles are loose. So if you wish to go ahead you have to exert more force on the sand as the particles will sink in a little i.e you are compressing the sand a little and hence a bit of your force is lost there. Whereas in concrete the particles are tightly packed and barely gets compressed. Hence only the threshold force is required for you to move forward.
To squeeze the particles closer together?
Under the influence of external pressure the particles are forced together. Under the particles' own gravitational force the particles come together. Technically speaking there must be an external force to bring the particles of matter together. Another point to be noted is that when the particles moves so close to together that it crosses its critical mass a black hole is developed. But not always.
Which rock is formed when particles stick together?
The rock formed when particles stick together is called Sedimentary Rock. The type of this rock depends on the composition and texture of the particles sticking together.
What do particles do when sound is louder?
they stick together
Why sand never blows where there are plants?
Desert regions are dry and the sand particles are easily stirred up by the wind. Plants need to be able to put down roots and draw moisture so they can grow. In areas like the coastal beaches, where the sand is moist and plants can grow, the sand particles tend to stick together and are not easily blown about by the wind.
How does the texture of clay differ from the texture of sand?
The texture of clay is smooth and cohesive, with fine particles that stick together. It is moldable and can be shaped easily. In contrast, sand has a gritty texture with larger particles that do not stick together easily. It is loose and granular, making it ideal for building and pouring.
What causes the particles to the atom to stay together?
Particles in an atom have opposite electrical charges, which cause the particles to attract each other, kind of like how positive and negative magnets stick together.

Sandstone is formed from tiny particles of sand cemented together Sandstone is?
Sandstone is a sedimentary rock. it is formed by the consolidation and compaction of sand and held together by a natural cement, such as silica.
What is the ability of particles to stick together and pull each other along?
The tenseness and pressure keeps them stuck together.
What problem is created if the sand is too wet?
the solution will be more liquid and will not stick together
What occurs when small particles collide and stick together to form larger masses?
accretion
Is sand a sedimentary rock or is lots of sand joined together a sedimentary rock?
Sand is composed of small loose particles of eroded rock of any type, but commonly it is particles of quartz from igneous or metamorphic rock. Each sand grain is actually a rock unto itself. Only when the sand grains are cemented together through a process known as lithification, do the sand grains become part of a new sedimentary rock.
What chemical is added to make particles stick together?
These substances are called caking agents or agglomerants.
