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

A

The crust,The mantle,The inner core and the outer core

48
Q

What material is the crust usually made of under the oceans

A

Basalt

49
Q

Which layer in the Earth is the coldest

A

The crust

50
Q

Where is the crust at its thinnest

A

Under the oceans

51
Q

What temperature is the mantle

A

Approximately 1000 degrees celcius neer the crust and 3700 degrees celcius near the outer core

52
Q

What is the Outer core made of

A

Semi liquid iron

53

A

Mainly iron and nickel

59
Q

Why are the rocks in the inner core still solid

A

Because the pressure in the inner core is 4 times more than the crust

60
Q

A

The Eurasian Plate

61
Q

Where do most earthquakes occur

A

Tectonic plate boundaries

62
Q

What is a destructive plate boundary

A

where two plates are moving towards each other, one of which is continental crust and one is made of oceanic crust

63
Q

What are fold mountains

A

large mountain ranges formed by the collision and ‘folding’ of two plates as they plates continually push into one another

64
Q

What are Ocean trenches

A

They are deep points in the ocean where the oceanic and continental crust have dragged each other downwards

65
Q

What are subduction zones

A

They are when one plate is forced downwards below another plate and grinds past it causing huge amounts of friction and heat

66
Q

What are more dense Oceanic crust or continental crust

A

Oceanic crust

67
Q

What is a Composite Volcano

A

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
