The name of the sea floors.
The abyssal plains.
Definition of coasts
The areas of contact between the surface of the continents and the oceans and seas
Definition of relief
The set of shapes that the Earth's surface has
Three main internal agents of relief
Volcanoes, earthquakes and orogenesis
Two words that describe mountains that are grouped into large groups
Ranges and chains
Definition of oceanic trenches
Long and narrow depressions
(Fill in the missing word) '....... are flat surfaces at the seashore formed by the accumulation of sediment, like sand or stones'
Beaches are flat surfaces at the seashore formed by the accumulation of sediment, like sand or stones'
Cause of relief formation
Relief formation is caused by internal forces
What the Earth's forces create
The Earth's forces create shapes or structure of relief
Definition of plains and plateaus
Plains are extensive flat areas, located at less than 200 metres above sea level. Plateaus are elevated planes at over 200 metres altitude
A gentle slope that extends the continents under marine waters
The continental shelf
River or glacial valleys flooded by the sea
Estuaries and fiords
Cause of relief modification
Relief modification is the result of the action of agents of erosion
Definition of volcanoes and where they are mostly located.
Volcanoes are cracks in the Earth's crust through which magma and gases from inside the Earth are released to the outside. They are mostly located in boundaries where plates meet
A description of 'depressions' and what causes them
Depressions are low areas, caused by the subsidence of a section of the Earth's crust
The depth of the sea floors
4000 or 5000 metres
Coastal land inlets in the sea
Capes
Another name for the action of the Earth's forces
Internal agents
'...... are also called seismic events. They are caused by ......' (Fill in the missing words
Earthquakes are also called seismic events. They are caused by the release of pressure because of the internal movements.
The name of a plateau in Asia that is located at more than 2000 metres
Tibetan Plateau
(Fill in the two missing words). 'The sea floor is mostly flat, but there are some irregularities, including oceanic trenches, ......... and ...........'
Oceanic ridges and underwater mountain chains
Description of an 'isthmus'
Part of the land that unites two larger land areas or joins a peninsula to the mainland
How the structure of relief is formed
The Earth's forces (internal agents) create shapes or structure of relief by raising, sinking or displacing blocks or sediment
Where the orogenesis process takes place
The process happens in areas where tectonic plates collide or move apart
