What is it called when a solid flows like a liquid?
Surface tension-Attractive forces cause particles on the surface of a liquid to pull together and resist from being pushed apart. These particles on the surface are pulled toward the center of the liquid and and sideways along the surface. There are no liquid particles above to pull on them. Particles under the surface are pulled in all different directions. Surface tension is the uneven forces acting on the surface particles of a liquid. Surface tension causes a liquid to act like it has a thin film stretched across the surface.
Why did mercury form spherical shape and the water not?
It is to do with the surface tension (ST). Mercury has very big ST. Water will form droplets too but on the oily surface. This is because water molecules form hydrogen bonds and the oily (organic) matter cannot form them. Thus, thermodynamically it is more favourable for water to have as little interactions with the organic surface as possible. This is achieved by reducing the surface area in forming a droplet. In a liquid a sort of internal pressure is created because the molecules that are inside (in the bulk) are pulled into all the possible directions, owever the molecules on the surface lack some of the pull. Therefore, they have higher energy and are pulled more inwards than outward. If you imagine all the molecules at the surface (when we imagine the hypothetical liquid being spread a lot) to be pulled in, the matter will 'pack' itself into the lower energy shape with reduced surface area - droplet.
The molecules at the surface of liquid water have greater attraction to each other than the molecules in the interior of the water because?
From wikipedia:"The cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero. The molecules at the surface do not have other molecules on all sides of them and therefore are pulled inwards. This creates some internal pressure and forces liquid surfaces to contract to the minimal area."
Why are rocks frequently pulled under the surface of the earth?
The rocks are frequently pulled under the surface because, Due to the movements in the crust.
Where does the undertow take sand and other particles from the shore?
they get pulled back into the ocean

What layer are cool particles pulled down by gravity?
ionosphere
What is apparent cohesion?
geology) In soil mechanics, the resistance of particles to being pulled apart due to the surface tension of the moisture film surrounding each particle. Also known as film cohesion.

What results when forces within earth are pulled horizontally in opposite directions?
shearing
Why needles can float?
The surface of a drop of water is always puling inwards pulling the surface of the drop as small as possible, this is called surface tension. A sphere is the shape with the least surface for its volume so surface tension tries to pull water droplets into spheres which is why they are round.If you very gently place a needle onto water so that it doesn't break the surface it;s weight will pull the surface downwards pulling it down, but because the surface is dented surface tension will pull it upwards stopping it sinking.Soap makes water's surface tension far weaker, allowing you to stretch it out into thin films in bubbles, and allowing it to stick to grease when you are doing the washing up. However it means that there is not enough force to hold up the needle any more and it sinks.Water is made up of tiny lumps called molecules - each one has 2 hydrogen and 1 oxygen atoms,, hence H2O. These molecules are moving about all over the place but they are very strongly attracted to one another.Molecules below the surface will get pulled in all directions by other molecules which cancels out . The molecules on the surface however are pulled inwards because there are no molecules above them.inwards all the time and pulled toward one another. This means that the surface acts like a slightly strange spring, as the surface grows or shrinks molecules are pulled into or out of the liquid out or from the surfaceSo if you look at the bottom of a dent in the surface there will be more water molecules above it than below it so it will get pulled upwards, shorteningExternal linkshttp://www.thenakedscientists.com/HTML/content/kitchenscience/exp/floating-needle/
