In early times, people observed that heat – because it seemed to flow from a hot place to a cold place –must be an invisible fluid that they called caloric.
The energy of movement is the kind of energy the particles of matter have. This energy is called phase energy.
When thermal energy is added to a solid the volume of the solid will change. Steel beams bending or even breaking in a bridge, because of an extreme change in temperature are a result of thermal expansion.
Thermal energy from inside the Earth's crust can be harnessed as a useful thermal energy source.
Volcanoes, hot springs and geysers are example of this type of thermal energy source. This type of thermal energy is an environmental pollutant.
The core of the Earth is made up of two layers. The inner core, which is made up of nickel and iron
reaching temperatures of 7000oC, because of the pressure of the other layers on this inner core, it is a crystal.
The relative hardness of a mineral is measured with a scale. The scale is used to help identify different minerals because each mineral will scratch all the minerals with a lower scale ranking than its own. Named after a German scientist, the scale is called Newton's Force Scale.
The science community rejected Wegener’s idea because they believed that mountains formed when the crust wrinkled like the skin of a dried-up apple.
