I have a upcoming project on Earth Science - a subject we we're not taught and have to learn ourselves through researching the project; which is so lame! Could someone give me a brief explanation to these answers? You don't need to answer all if you don't know any, but please indicate the number. You also are not required to fully explain, as I will research it myself anyways. Thanks!
5.Explain how plate movement produces the following:
a) epicentres and shallow focus to deep focus earthquakes
b) volcanism at subduction zones and at spreading ridges
c) mountain ranges and mid ocean ridges
d) hot spot chains (hawaiian islands, yellow stone)
6. Identifity sources of heat within the Earth that produce mantle convection and hot spot activity (i.e heat within the core)
7. Explain how mantle convection and ridge push and slab pull are believed to contribute to plate motion
8. Describe evidence for continental drift theory
9. Relate the following to plate tectonic theory: - The world distribution of volcanoes, earthquakes, mountainbelts trenches, mid-ocean ridges, and rift valleys - hot spot and subduction zone eruptions, magnetic reversals and age of rocks relative to spreading ridges
