Rocks

Question 1

Igneous

Answer 1

Made from magma cooling
Crystallised
Basalt is extrusive (cools on the surface) small crystals as it cools quick
Granite is intrusive (cools underground) big crystals as it cools slowly

Question 2

Sedimentary

Answer 2

Weathered igneous rock is transported by rivers to the sea and over long periods of time is built up in layers
Compaction
Fossils are found inside then
Chalk 
Limestone

Question 3

Metamorphic

Answer 3

Formed by heat and pressure of sedimentary rock

Marble

Question 4

What happens at oceanic and continental plate boundary

Answer 4

Oceanic is thinner than the continental crust, but it is denser (heavier), so it subducts under it
Oceanic is a lot younger

Question 5

The subduction and melting of sedimentary rock and metamorphic rock does what

Answer 5

Turns it all back into magma (igneous) rock and the process starts again

Question 6

How is a Cuesta and chalk escarpment formed

Answer 6

Under the sea, earthquakes cause it the to rise above sea level, earthquake forces the clay and chalk to move to a 45 degree angle, the clay is then eroded quicker then the chalk leaving dips in the landscape. Steep slip is a scarp slope and shallow slope is a dip slope.
