19. 1.Deltas and canyons 2.deposition

20. You can find examples of the different forms of energy in nature. Lightning: natural example of electrical energy. Heat energy inside Earth: warms underground water and rock, producing geysers and volcanoes. Fireflies: are natural examples of light sources. The Sun: most important light source for Earth. Light from the Sun is a form of solar energy. ____________, from nature, has the same energy as that provided by batteries. Why?

21. Lightening! Lightening can provide an electrical current, just like batteries. Benjamin Franklin discovered that lightening held an electrical charge.
