What is the outermost layer of the Earth
called?
The
crust
View source
What causes tectonic plates to move?
Convection currents
in the mantle
View source
What is slab pull?
A force causing
tectonic
plate movement
View source
Where are tectonic hazards mainly found?
At
plate boundaries
View source
How do continental and oceanic plates differ in density?
Continental
plates are
less
dense
than
oceanic
plates
View source
What are the types of tectonic plate boundaries?
Collision
Constructive
Destructive
Conservative
View source
What causes earthquakes?
Release of stored energy in
plates
View source
What is the focus of an earthquake?
The
underground
point where
energy
is released
View source
What is the epicenter of an earthquake?
The point on the surface directly above the
focus
View source
How does the depth of the focus affect earthquake severity?
Deeper
focuses tend to be
less
severe
View source
What type of volcano is characterized by high viscosity lava?
Composite volcanoes
View source
What are the primary effects of an earthquake?
Ground shaking
and
infrastructure
damage
View source
How are earthquakes measured?
Using the
Richter scale
View source
What magnitude on the Richter scale is considered severe?
Anything over
6
View source
Why was the damage from the Haiti earthquake worse than expected?
Poor building
standards
and dense populations
View source
What hindered aid efforts in Haiti after the earthquake?
Significant damage to
infrastructure
View source
What was the magnitude of the Haiti earthquake in January 2010?
7.0
View source
What was a major criticism of international aid in Haiti?
Slow
response
and poor local
collaboration
View source
How did the earthquake impact Haiti's economy?
Caused
huge
poverty and loss of trade
View source
What technology can help predict potential earthquake danger?
Satellite
technology measuring
plate movement
View source
What are P waves?
Fast traveling primary waves from
earthquakes
View source
How can alerts be communicated before secondary waves arrive?
Using
SMS
,
sirens
, and radio
View source
What building features can reduce earthquake damage?
Triangular supports
and
shock absorbers
View source
What are the processes involved in extreme weather patterns?
Rising hot air creates
convection currents
Evaporation
leads to
condensation
and
precipitation
High pressure zones
lead to dry conditions
Heavy precipitation
can cause flooding
View source
Where are tropical cyclones located?
5°
either side of the
Equator
View source
What effect does the Coriolis effect have on tropical cyclones?
Causes
them
to
spin
in
different
directions
View source
What happens to a tropical cyclone when it reaches land?
It stops due to lack of
evaporation
View source
What triggers drought conditions during El Nino years?
Weaker
trade winds
and reversed
ocean currents
View source
What was the rainfall reduction in Australia during the Big Dry?
40-60%
less rainfall
View source
What measures did the Australian government take during the Big Dry?
Offered
subsidies
for water conservation
View source
What caused the flash floods in Boscastle in 2004?
Heavy
rain
and
deforestation
View source
How many people were rescued during the Boscastle flood?
150
people
View source
What measures were taken after the Boscastle flood?
Afforestation
and improved
flood defenses
View source
What is the Quaternary period known for?
Cyclical
patterns of climate change
View source
What is Milankovitch cycles theory?
Earth's
path changes affecting climate
View source

Sea level rise causing flooding
View source
How is the economy of Tuvalu affected by climate change?
Saltwater intrusion
makes land infertile
View source
What are the expected effects of climate change in the UK?
Increased
flooding
and species migration
View source
What are the major processes of river and coastal landscapes?
Erosion
: Breaking down rocks
Transportation
: Moving eroded material
Deposition
: Dropping off material
View source
What are the types of weathering?
Mechanical
,
chemical
, and
biological
