Increasing the amplitude of the atoms vibrations
A common difficulty caused by thermal expansion is the warping or cracking of materials such as metal or concrete when they are exposed to extreme temperature changes. For example, railroad tracks can buckle in hot weather due to thermal expansion if proper allowances are not made.
In a solid, thermal expansion occurs as the temperature increases, causing the atoms or molecules to vibrate more, increasing the average distance between them. As a result, the solid expands in all directions. In a gas, thermal expansion occurs as the temperature increases, causing the gas molecules to move faster and spread out, increasing the volume of the gas.
Two examples of thermal expansion in solids are the expansion of a metal rod when heated, causing it to increase in length, and the expansion of a bridge beam on a hot day, resulting in the beam bending slightly due to the increase in temperature.
The reason there are cracks in sidewalks instead of just one continuous piece of concrete is to provide for thermal expansion. Without the expansion cracks, as the concrete heats up it expands it would have no where to go so the sidewalk would buckle. Also, in the winter when it gets cold the concrete would shrink and crack/break.

The purpose of a thermal expansion tank for a water heater is to accommodate the expansion of water as it heats up, preventing pressure buildup in the plumbing system. This helps to prevent issues such as leaks, burst pipes, and damage to the water heater caused by the increased pressure from thermal expansion.
Thermal Expansion is being affected by temperature because the substance's temperature increases and therefore it makes the particles move faster and spread out. Also, it causes more space between the particles which then makes the substance expand. Alcohol in a thermometer is expanding and that is also caused by Thermal Expansion. Not only that but, Mercuy is also used in thermometers which again like I said before is caused by Thermal Expansion which to then makes the thermometer expand the red liquid.

Not sure what you mean; basically, ANY solid will expand if you heat it.
It is generally called "Chip Creep".
Since expansion is the process of a substance's dimensions increasing, e.g., thermal expansion caused by a rise in temperature, the logical opposite would be contraction.
The increase in area of a solid on heating is called thermal expansion. This occurs because the particles within the solid gain energy with heat, causing them to vibrate and move further apart, which leads to an increase in the solid's dimensions.
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
