Drawing Geologic Time

1. Watch this movie = https://www.brainpop.com/science/earthsystem/geologictime/ 2. Complete this worksheet with LABELING tool 3. Explain your answers "Oceans have formed, continents have moved, mountains have risen, animals have evolved and gone extinct. To organize major changes, scientists have broken the Earth's timeline into sections lasting millions of years. This is called the geologic time scale. Instead of millennia, centuries, and years, the geologic time scale is broken up into eons, eras, periods, and epochs. The Earth has had four eons, each lasting hundreds of millions to billions of years. Each of these eons is broken up into two or more eras, which are broken into periods, which are broken into epochs. All these units are of relative length, so they have no set number of years. The actual length of each unit depends on what geologic changes occurred in it. Like, one eon could contain a single era that's longer than another."
