Q

What are convection currents

A

Magma is heated to 5000 degrees celcius in the mantle and rises to the crust where they cool and sink only to be heated again. The
process continues. This was powerful enough to move the earth’s plates.

Q

The third piece of evidence Alfred Wegener was The study of fossils.What was it about

A

Similar fossils are on different continents and the species could not have crossed oceans so they must have lived when the continents where still conected

Q

Alfred Wegener’s forth piece of evidence was Geological patterns.What was this about

A

Similar pattern of rock lauers on different continents.Coal was also found in Antartica.Coal only formes in warm conditions which means antartica used to be in a warmer part of the world

33
What will happen at a conservative(transform) plate boundary
Cone/Composite Volcano and Earthquakes
34
What will happen at a convergent(collision) plate boundary

35
What are the two scales we use to measure earthquakes
The richter scale and the mercalli scale
36
Which scale measures the magnitude of a earthquake
The richter scale
37
How does the mercalli scale measure a earthquake
Visual observations to measure the impact of the earthquake
38
What units are used when measuring a earthquake with the mercalli scale
Roman numerals from I to XII
39
What is pyroclastic flows
Fast moving currents of hot gas and rock from a volcanic eruption
40
What is a lahar
Violent type of mud flow or debris flow from a volcanic eruption
41
Why do people live in volcanic areas
Fertile land for crops Jobs in tourism Selling ash They have no choice Attractive lanscape
42
What is the advice given to students in earthquake prome countries
Drop,Cover,Hold on
43
What are the main cause of earthquakes
Movement of tectonic plates
44
What are some of the secondary effects of earthquakes
Tsunamis
45
What does GDP stand for
Gross Domestic Product
46
Which country is often reffered to as the leading Superpower
The United States of America
47
What are the 4 layers of the Earth
The crust,The mantle,The inner core and the outer core
48
What material is the crust usually made of under the oceans
Basalt
49
Which layer in the Earth is the coldest
The crust
50
Where is the crust at its thinnest
Under the oceans
51
What temperature is the mantle
Approximately 1000 degrees celcius neer the crust and 3700 degrees celcius near the outer core
52
What is the Outer core made of
Semi liquid iron
53
What temperature is the outer core
3700-5000 degrees celcius
54
How thick is the outer core
Approximately 2300KM thick
55
Where is the Earths magnetic field formed
The outer core
56
How thick is the Inner core
1250KM thick
57
What temperature is the Inner core
Over 5000 degrees celcius
58
What materials is the inner core made up of
Mainly iron and nickel
59
Why are the rocks in the inner core still solid
Because the pressure in the inner core is 4 times more than the crust
60
What tectonic plate is the UK on
The Eurasian Plate
61
Where do most earthquakes occur
Tectonic plate boundaries
62
What is a destructive plate boundary
where two plates are moving towards each other, one of which is continental crust and one is made of oceanic crust
63
What are fold mountains
large mountain ranges formed by the collision and ‘folding’ of two plates as they plates continually push into one another
64
What are Ocean trenches
They are deep points in the ocean where the oceanic and continental crust have dragged each other downwards
65
What are subduction zones
They are when one plate is forced downwards below another plate and grinds past it causing huge amounts of friction and heat
66
What are more dense Oceanic crust or continental crust
Oceanic crust
67
What is a Composite Volcano
They are very steep volcanos formed on a destructive boundary.The magma inder the surface has high silica levels and is very explosive which makes Composite Volcanos the most dangerous Volcanos
