Six Key Questions
1.
2.
3.
What is the nature of deformation at
plate boundaries and what are the
implications for earthquake
hazards?
4.
How do magmatic systems evolve
and under what conditions do
volcanoes erupt?
5.
What are the dynamics of the mantle
and crust and how does the Earth’s
surface respond?
6.
What are the dynamics of the Earth’s
magnetic field and its interactions
with the Earth system?
How do tectonics and climate
interact to shape the Earth’s surface
and create natural hazards?
What are the interactions among ice
masses, oceans, and the solid Earth
and their implications for sea level
change?
