3
Archaeopteryx is evidence that
present day organisms have developed from past life forms.
the first vertebrates had feathers
only animals with hard body parts form fossils.
birds evolved into reptiles.
4
What was the main reason for phasing out CFCs , used in aerosols and refrigerants?
They were a limited industrial resource

13
What is the main effect of the impact of a raindrop on loose soil in a ploughed paddock?
Compaction of soil
Decrease in permeability
Displacement of surface particles
Increase in soil particle size
14
How was this rock formed?
Alternating O2 rich & O2 poor waters in early Proterozoic

To replace the use of irrigation
To reduce the rate of soil loss
To prevent an increase in pest populations
To prevent the formation of lateritic soils
16
Where is a deep focus earthquake most likely to occur on the Australian–Indian Plate?
At the continental margin east of New South Wales
At the subduction zone along the northern plate boundary
At the mid-oceanic ridge along the southern plate boundary
