Energy Transformations
module 3
Role of Energy in the Earth’s Processes
How does energy drive the Earth’s processes?
analyse the role of solar radiation in driving the Earth’s processes,
photosynthesis
water cycle
investigate the role of gravity and heat in tectonic plate movements
comparing the movement of the Earth’s plates to surface movements of other bodies in the solar system
modelling movement caused by gravity and heat
describing the contributions of convection and slab pull to plate speed
conduct a practical investigation to demonstrate convection currents
Geological Transformations: Earthquakes, Volcanoes and Mountain Range
s
How do energy transfers and transformations alter the lithosphere?
explain how the release of elastic potential energy in rock leads to earthquakes
describe the role of heat and its interactions with the lithosphere in creating different types of volcanic eruptions and magma compositions
thermal plumes resulting in effusive mafic eruptions
partial melting of subducted oceanic plates resulting in explosive felsic eruptions
interactions of magma and overlying ice resulting in ash clouds
represent these energy transformations in the formation of mountains due to
thermal expansion
deformation of the lithosphere
Transformations in the Oceans, Biosphere and Cryosphere
How do energy transformations influence the atmosphere, oceans, biosphere and cryosphere?
investigate the unique properties of water that make it such an important component of the Earth’s systems
– boiling point
– ability to act as a solvent
– density
– thermal capacity
– surface tension
outline the roles of energy, water masses and salinity in producing ocean currents
extract information from secondary sources to document and investigate changes in the cryosphere
explain the role of heat transfer by ocean currents and atmospheric movement in causing phenomena
