FOUNDATION
•
Describe the structure of the Earth as a sphere
with a thin rocky crust, a mantle and an iron core.
MULTI-STRUCTURAL
Understand how the movement of tectonic plates
results in volcanic activity and earthquakes.
MULTI-STRUCTURAL
•
Recall that the movement of tectonic plates is very
slow (about 2.5cm per year).
UNI-STRUCTURAL
•
Understand the timescales involved in the
movement of continents.
MULTI-STRUCTURAL
•
Recognise that: many theories have been put
forward to explain the nature of the Earth’s
surface.
MULTI-STRUCTURAL
•
Earth scientists accept the theory of plate
tectonics.

STANDARD

•
•
•
Describe the lithosphere as the (relatively) cold
rigid outer part of the Earth that includes the crust
and part of the mantle.
MULTI-STRUCTURAL
Describe the lithosphere as made of tectonic
plates that are less dense than the mantle below.
MULTI-STRUCTURAL
Explain the problems associated with studying the
structure of the Earth:
• crust is too thick to drill through
• the need to use seismic waves produced by
earthquakes or man-made explosions.
Explain why the theory of plate tectonics is now
widely accepted:
• it explains a wide range of evidence
• it has been discussed and tested by a wide range
of scientists.

•
Describe the mantle as the zone between the crust and the core
which is:
• cold and rigid just below the crust
• hot and non-rigid at greater depths and therefore able to move.
Describe the theory of plate tectonics:
• energy transfer involving convection currents in the semi-rigid
mantle causing the plates to move slowly
• oceanic crust more dense than continental crust
• collision between oceanic plate and continental plate leads to
subduction and partial melting
• plates cooler at ocean margins so sink and pull plates down.
Describe in simple terms the development of the theory of plate
tectonics:
• Wegener’s continental drift theory (1914)
• continental drift theory not accepted by scientists at the time
• new evidence in 1960s – sea floor spreading
• theory of plate tectonics slowly accepted by the scientific
community as subsequent research has supported the theory.
