Inside the Earth
What is the outside layer of the Earth called?
the crust
What are tectonic plates?
big rigid pieces of the earth's outer layer
What is a natural hazard?
a natural event that could hurt people or places
A tall steep volcano with layers of ash and lava is a... a) shield volcano b) composite volcano c) cinder cone
b) composite volcano
A student wrote - From the outside the layers are core, mantle, crust.
from the outside it is crust, mantle, core
Which layer is at the centre of the Earth?
the inner core
At a constructive boundary, do plates move apart or together?
apart (new crust is made)
A drought is caused by weather. What type of hazard is this?
a climatic hazard
A volcano with wide gentle slopes and runny lava is a... a) cinder cone b) composite volcano c) shield volcano
c) shield volcano
A student wrote - The lithosphere = crust + hot part of the mantle.
the lithosphere = crust + rigid upper part of the mantle
Put in order from the outside - core, crust, mantle.
crust, mantle, core (outer core then inner core)
At a conservative boundary plates slide past each other. What hazard can happen?
earthquakes
An earthquake is caused by moving plates. What type of hazard is this?
a tectonic hazard
Mount Fuji in Japan is a... a) composite volcano b) shield volcano c) cinder cone
a) composite volcano
A student wrote - At a destructive boundary the continental plate sinks.
the oceanic plate sinks because it is heavier
Heat from the core makes the mantle rock move in big slow circles. What are these called?
convection currents
Two continental plates push together. What type of boundary is this?
a collision boundary
A volcano erupts on an empty island where nobody lives. Is this a natural hazard? Why or why not?
no, it is not a hazard because no people or property are in danger
Which one is a shield volcano in Hawaii? a) Mount Etna b) Mauna Loa c) Mount Fuji
b) mauna loa
A student wrote - Type composite. Example a big volcano near the sea.
name a real volcano, for example mount fuji
The lithosphere = crust + which part of the mantle?
the rigid upper part
What landform is made at a collision boundary? Give one example.
fold mountains, for example the himalayas
Give two reasons why an earthquake in a poor country often kills more people than one in a rich country.
weaker buildings, less money for warnings and rescue, fewer hospitals or less training
Paricutin in Mexico is a... a) shield volcano b) composite volcano c) cinder cone
c) cinder cone
A student wrote - Volcanoes are less common at collision boundaries because the plates are very strong.
no plate sinks so less magma is made
