- The Atlantic Ocean is expanding due to diverging plates.
- Northeastern Africa is splitting due to diverging plates.
Why Do We Need To Know About Divergent Boundary
Learning about divergent boundaries helps us understand how Earth’s surface changes and why it’s important for predicting natural disasters. Divergent boundaries are where the Earth’s plates move apart from each other. This knowledge is used by scientists like those studying earthquakes and volcanoes to save lives and protect homes by predicting disasters.
Studying these boundaries also teaches us about how the Earth and other planets have changed over time and how new land is formed. This is key for scientists looking at Earth and exploring other planets like Mars, helping us learn more about space.
