Fast & Slow Earth Changes
Understand that Earth's surface changes: some changes are quick (eruptions, earthquakes) and some are slow (wind, water wearing away rock)
What a learner can do afterwards
- Give an example of a quick change to Earth's surface like a volcanic eruption
- Give an example of a slow change to Earth's surface like erosion by wind or water
- Compare quick and slow changes and explain the difference
The lesson
Earth's surface changes all the time. Some changes happen fast. Some changes happen very slowly.
Waves hit a rocky cliff every single day. After many years, the cliff wears away.
Ask yourself: how long did it take? Minutes or hours means a fast change. Years and years means a slow change.
Quick changes take minutes or hours; slow changes take many years.
