1. Effects of Tectonic Activity

2. Volcanic Effects Lava: buries whatever is in its path
Pyroclastic Clouds: burn, bury or asphyxiate everything in their path
Ash: various sizes falling back to Earth; finer stuff getting up into atmosphere; lethal to plants, animals, and people

3. Debris Flows: similar to rock slides
Lahars: hot ash melts surrounding snow or ice and creates a muddly river
Craters and calderas: when the top of the volcano is blown off; when it collapses in on itself

4. Also, injects huge amounts of CO2, SO2, HCl, HF and ash into the air
Also, injects huge amounts of CO2, SO2, HCl, HF and ash into the air. Can cause:
Coolingfood supplies
Destruction of ozone
Acid rain
Global warming

5. Upwelling Hot spots and divergent boundaries
Water from hot fissures is warm and nutrient rich
Bacteria thrive and bring other ocean organismsbiological community!

6. Effects of Earthquakes
Aside from fear created by shaking:
Liquefaction
Landslides
Tsunami
Damage to buildings

7. Mountain Building How might this affect plant and animal life?
Diversity
How might this affect waterways?
Drainage patterns, rivers
