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 standard unit of measuring force is named after a famous English scientist, who was the first todescribe the ‘law of gravitation’, getting the idea for the law as he sat under an apple tree. This unit ofmeasuring force is similar to the amount of force needed to hold an apple in your hand and is called a Newton.

The core of the Earth is made up of two layers. The inner core, which is made up of nickel and ironreaching 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 differentminerals, 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.

When engineers build bridges, they take two conditions into account: what the bridge is crossing and what kinds of loads it will support, to decide which type of bridge will best suit the situation. Which type of bridge would engineers suggest to withstand very heavy loads?
