Emerging and developing country (EDC)
countries which neither share all the economic development characteristics required to be advanced or are eligible for the Poverty Reduction and Growth Trust; EDCs are classified by the IMF
Epicentre
the point on the Earth’s surface directly above the focus
fault
like a fissure, this is a split in the rock; in plate tectonics this is where the plates are moving, e.g. the San Andreas Fault
fissure
a narrow opening in the Earth’s crust caused by splitting (e.g. because of tectonic movement)
Friction
when plates rub against one another to create heat and stress, which will lead to rock melting and snapping
front
a boundary separating two masses of air with different densities, usually heavier cold air and lighter warm air
Glacier
a frozen river of ice formed by snow and ice accumulating in mountains or polar areas, which can even form on top of volcanoes (e.g. in Iceland)
Greywater
recycled waste water from showers, baths, wash basins and washing machines
hazard
a danger or risk; tectonic hazards include volcanic eruptions, earthquakes, landslides, etc.
heatwave
a prolonged period of abnormally hot weather
Hemisphere
a half of the earth, usually as divided into northern and southern halves by the Equator
High pressure
when there is more air pressing down on the ground, caused by air sinking; air descends as it cools, leading to high pressure at the surface
hotspots
weaknesses in the Earth’s crust where rock is thinner, which allows magma to the surface even though it is not at a plate boundary
Infrastructure
the basic structures and facilities needed for a society to function, such as buildings, roads and power supplies
Intertropical convergence zone
a low-pressure belt that encircles the globe around the Equator; it is where the trade winds from the northeast and southeast meet; the Earth is tilted on its orbit around the Sun, causing the ITCZ to migrate between the Tropics of Cancer and Capricorn with the seasons
