Atmosphere
The layer of Earth’s gases above the Earth’s surface
Collision Zones
Where two tectonic plates collide e.g Himalayas
Conservative Plate Boundary
Where two plates slide along each other
Continental Crust
The part of the Earth’s crust that makes up land (30-50km thick)
Convection Currents
Currents which transfer heat from one part of a gas or liquid to another
Convergent Plate Boundary
When two tectonic plates collide (see collision zone)
Core
Centre of the Earth, made up of a solid inner and molten outer core
Coriolis Force
A strong force created by the Earth’s rotation (within 5º of the equator), can cause hurricanes and tropical storms
Cumulonimbus Clouds
Tall clouds created by the condensation of water vapour
Divergent Plate Boundary
Where two tectonic plates move away from each other
Enhanced Greenhouse Effect

Eye of the Storm
The centre of a storm, consists of calm, descending dense air
Ferrel Cell
Part of the globe circulation model, where Earth’s atmosphere consists of cool, descending, dry air
Friction
The force which resists the movement of one surface over another
Global Circulation Model
Theory explaining how the atmosphere operates in three cells either side of the equator
Greenhouse Effect
The way that gases in the atmosphere trap heat from the sun
Gulf Stream
A warm ocean current which begins in the Gulf of Mexico and is blown NE across the North Atlantic
Hadley Cell
Largest section of the global circulation model, caused by heating and cooling of Earth’s atmosphere
Hot Spots
Columns of heat in the Earth’s mantle found in the middle of a tectonic plate
Ice Cores evidence of climate change
Columns of ice that are extracted from ice sheets and used to construct temperature patterns
