2.3 Tectonic Landscapes

HideShow resource information
Crust
8-65km thick, the crust is the outer layer of the earth. made of solid rock, the crust is the layer upon which we live.
1 of 17
Mantle
the widest section, approximately 2,900km thick. in the upper mantle, the semi-molten rock is hard, but lower down it begins to melt and becomes soft.
2 of 17
Outer Core
made up of liquid iron and nickel, the outer core is the layer surrounding the inner core.
3 of 17
Inner Core
the centre and hottest part of the earth. it is made up of solid iron and nickel, reaching temperatures of up to 5,500 degrees celsius.
4 of 17
Magma
liquid rock below the earth's surface
5 of 17
Lava
liquid rock above the earth's surface.
6 of 17
Tectonic Plates
large slabs of rock which make up the earth's crust.
7 of 17
Richter
measures the strength of an earthquake
8 of 17
Mercalli
measures the strength of an earthquake
9 of 17
Oceanic
a plate beneath an ocean. these are young, heavy and thin.
10 of 17
Continental
a plate beneath a continent. these are old, thick and light.
11 of 17
Conservative (Transform)
two plates sliding past each other.
12 of 17
Constructive (Divergent)
two plates moving apart.
13 of 17
Destructive (Convergent)
an oceanic plate forced beneath a continent plate - also known as subduction
14 of 17
Collision
two plates moving towards each other.
15 of 17
Focus
the point where the pressure is released (earthquakes).
16 of 17
Epicenter
the point immediately above the focus. a earthquake is stronger near the epicenter.
