What makes an earthquake?
Earthquakes are the vibrations caused by rocks breaking under stress. The underground surface along with the rock breaks and moves is called a fault plane.
100
How are mountains formed by plate tectonics?
Land masses rubbing together and rising up.
100
Where are the tectonic plates located?
The tectonic plates are located under the Earths Crust.
100
What is a continental Drift?
When our continents separated and drifted in to 7 continents we have today.
100
What causes a natural disaster?
Thermonuclear activity on the centre of the earth Moving of earth's plate Human exploration gone wrong Plague
200
How do earthquakes cause damage.
Most earthquakes cause damage by the shaking of the ground which can trigger off natural disasters such as tsunamis, floods .e.t.c.
200
How are volcanic mountains formed?
Volcanic mountains form as lava oozes from cracks from under the earth.
200
How do Tectonic Plates relate to earthquakes?
When the tectonic plates slide against each other and move under each other they cause earthquakes.
200
What is the name of single continent that used to exist in this world?
Pangea

Name 5 natural disasters.
Tsunami Tornados Earthquakes Floods Bushfires Landslides

Can Earthquakes be predicted.
They cannot be predicted.
300
What is a big component in a mountain forming?
Thrust and reverse fault movement are an important component of mountain formation.
300
How are land features reshaped by plate tectonics?
Land features are changed by plate tectonics because they slowly move around forever changing shape.
300
Who first proposed the theory of the continental drift?
Alfred Wegener
300
In what country did the strongest earthquake on record occur?
Chille.
400
What has been the highest magnitude ever recorded?
9.5 magnitude
400
What is a block mountain?
When a fault block is raised or titled, block mountains are the result.
400
What are the convection currents?
A cycle of which heat energy in a liquid rises to the top then becomes dense because it is further away from the heat source at the bottom.
400
Do the countries still move around?
Yes they do.
400
Which natural disaster cannot be cause by shifts in tectonic plates?
Hurricane
500
What has been the most devastating earthquake ever recorded?
May 22 1960 - Chile

What is Fault blocks?
Several movements of the earths crust that lead to mountains are associated with faults.
500
How do plate tectonics cause volcanoes?
Volcanoes are caused by convergent plates, which is when the crust is consumed.
500
How does fossil evidence help prove the theory of continental drift?
Similar fossils could of been found on separate continents.
