Scientist Nina and her young explorers learn about planet Earth and the solar system. Nina investigates how mountains were made with the help of Luke, her sight neuron.

Explorers Kaiden and Tyler visit Nina in her workshop and, with the help of Luke, her sight neuron, discover that the Earth is covered in big plates of rock that move around very slowly, sometimes pushing together and squashing up to make mountains. Then they visit Beinn Eighe mountain in the Scottish Highlands and take a closer look on a helicopter ride.
