Geoscience Education Research Groups have been established around the world to address the challenges facing geoscience education and to improve the effectiveness of teaching methods. These groups bring together geoscientists, educators, and researchers to explore how to engage and motivate students to learn about the Earth and its complex systems.
How important is this double role of sediment for the evolution of landscapes? [7] [8] How resilient is the ocean to chemical perturbations? [citation needed] What controls the dynamics of storm tracks? [9] Why do we have the number of tropical cyclones that we do? [10] Mechanisms that cause oscillations in equatorial climate remain under ...
