Module 5:Earth’s Processes
Development of the Biosphere
How did today’s biosphere originate and develop?
investigate evidence for the origin of organic molecules on the Earth
Urey and Miller’s experiments
communities around Black smokers
meteorites/panspermia
investigate the evidence for the development of photosynthetic life, including cyanobacteria and stromatolites
evaluate the evidence for the origin of multicellular life and resulting changes to ecosystems, for example, the Ediacaran and Cambrian fauna
investigate the conquest of land by both plants and animals
Changes in the Geosphere, Atmosphere and Hydrosphere
How did the changes to the biosphere affect the Earth’s geosphere, atmosphere and hydrosphere?
analyse the changes in the geosphere, atmosphere and hydrosphere that resulted from the development and evolution of the biosphere
effect of photosynthesising cyanobacteria on each of the spheres
role of oxygen in the production of banded iron formations
Plate Tectonic Supercycle
What effect does the plate tectonic supercycle have on the Earth
?
model the plate tectonic supercycle
outline the effect of the plate tectonic supercycle on large-scale phenomena, including climate and evolution
Fossil Formation and Stratigraphy
What is the role of fossils in expanding what is known of geological time and past life on Earth?
investigate and model processes of fossil formation by examining a variety of methods in rock, including
mould formations
cast formations
trace fossils
discuss the significance of index fossils in generating a geological timescale
extrapolate how the principles of uniformitarianism and superposition as well as fossils and absolute dating can be used to date events of geological significance, for example
the evolution of the Cambrian fauna
mass extinction events
