What are the two terms are used to describe two scenes?
Rural-country side urban-city
What are the key terms used to describe plants and animals in an ecosystem?
Fauna and flora
What is an ac?
Advanced country (rich developed country)
What is a lidc?
Low income developing country
What is an edc?
Emerging developing country
What is gis?
A system designed to capture ,store ,manipulate,analise ,manage and present spatial or geographic data
What does tea stand for?
Trend ,example and anonoly
What is a ridge push?
New crust rises because it is warm and thin ,creating a ridge
It pushed older crust away from them ridge
What is a slab pull?
Old crust which is cooler and thicker than the hot mantle so it sinks into the mantle
What is a destructive plate boundary and its factors?
It’s when two plates push together destroying oceanic plate.
Denser oceanic plates will subduct
It causes fold mountains
As the oceanic plate sinks into the magma it melts and the water inside it makes the mantle less dense causeing volcanic eruption
What is a collision boundary and what are its factors?
Two plates push together ,both of the same density so they just collide and push up against eachother (there is no subduction = no volcanoes)
Sqeeze upwards to create fold mountains (ground reshapes and buckles under pressure
Bad earthquakes can occur (break crust)
What is a constructive volcano and what are its factors?
Plates are separating by moving away from each other
Magma rises from the surface
Causeing volcanoes and new crust as lava emerges and spreads out
Under the ocean it causes rift valleys and mid ocean ridge
What is a conservative plate boundary and what are its factors?
It’s two plate boundary’s that slide past each other slowly
The plates are moving in the same direction but at different speeds or moving parallel to each other but in opposite directions
It causes friction till one plate snaps and moves forward
This causes violent earthquakes
What are shield volcanoes and what are there properties?
They are volcanoes that form hill like structures they have a centurion vent and a side vent
No trapped gases= gental euruptions
Runny lava due to low pressure
Form on constructive plate boundary’s due to hot spots
What are composite volcanoes and what are there properties?
They are a tall(mountainous) volcano that has 2 side vents a centural vent and has an ash cloud and acid rain.
It contains trapped sea water and hot gases this builds up pressure
Lava cools quickly
What are mantle plumes?
Upwelling of molten rock in the mantle which creates hot spots
What are hotspots?
Place where lava rises through the ocean crust forming shield volcanoes
What is liquefaction?
When the earth shakes and the ground acts like liquid ,sinking bulidings
What are the 7 elements of an earthquake?
Aftershock: small tremors that occur after an earthquake
Earthquake:sudden or violent movement within the earths crust followed by a series of aftershocks
Epicentre:point on the earths surface directly above an earthquake focus
Focus:source of an earthquake beaneath the earths surface
Magnitude:energy realised in an earthquake measured in the richter scale
Seismic wave:fast waves of energy generated from the focus of an earthquake
Seismic gap:area along known faults that has not experienced earthquake activity for a long time
What are seismologists and what do they do?
They study earthquakes and use seismometers to record the size of them
Minimise risk during earthquake
What is the Richter scale and what is its purpose?
The amount of energy realised in an earthquake is known as magnitude
It is a logarithmic scale
What is the mercalli scale and what is its purpose?
The intensity of an earthquake and the effects and damage causes can be measured use it the mecalli scale
The ranges to 1 to x11 level 1 can only be recorded on seismograms and cannot be felt
What is Nepal 2015?
The movement of the Indian and Eurasian plates colliding
Causeing an earth quake with the magnitude of 7.8 moving the crust 3m
How big was the population and what was there life expectancy in Nepal in 2015?
It had a population of 30 million and had the average life expectancy of 68 years
