The two mosy well-known internal processes are
Volcanoes and earthquakes
15
Internal geological processes are driven by
The Earth's internal heat
15
The point where an earthquake starts (deep within the earth) is called the
Focal point or hypocentre
15
In an earthquake, the point on the Earth's SURFACE closest to the hypocentre is called
The epicentre
15
Seismic waves transmit
Vibration
15
The formula for geological risks is RISK=
Hazard x vulnerability
15
True or fase: both volcanoes and earthquakes are located on the boundaries between plates
true
15
External geological processes are moved by ___ and ___
solar energy and gravity (solar energy evaporates water causing rainfall which leads to rock weathering and gravity makes rivers flow downstream+ affects tides)

Internal
15
Erosion, transport, sedimentation and diagenesis... are these internal or external processes?
external
15
True or false: magma has the same viscosity in all volcanoes
False... some have magma which is more viscose (thick) and others more fluid
