The Earths Surface (MOCK REVISION)

describe what happens when plates collide

one plate sinks into the mantle, forming fold mountains

what happens at plate boundaries

where plate tectonics meet, they cause volcanoes and earthquakes

describe what happens when plates seperate

magma rises to fill the gap (plates seperate)

describe what happens when plates slide past eachother

they build up pressure (sliding plates)

describe what happens at constructive plate boundaries

plates separate and new land is formed (constructive)

describe what happens at destructive plate boundaries

plates collide and sink (destructive)

what are convergent boundaries

boundaries that cause crust to be destroyed

what are divergent boundaries

boundaries that cause crust to be created

what are shear boundaries

boundaries that dont cause crust to be created or destroyed

example of separating plate boundary

mid atlantic ridge

example of colliding plate boundary

himalayas

example of plates sliding past eachother

san andreas fault, california

describe the pattern of tectonic activity along ‘The Pacific Ring of Fire’

an area with frequent earthquakes and volcanoes caused by tectonic plate subduction

describe how plate movement can lead to the formation of a volcano

magma rises through the crust (formation of volcano)

name one feature formed when plates collide

mountain range (collide)

name one feature formed when plates separate

mid ocean ridge (separate)

dormant volcano

sleeping but could erupt

active volcano

erupting

extinct

will never erupt again

describe what happens at a mid ocean ridge

earths crust splits apart and magma rises to form new crust

example of a volcano

mount st helens 1980

social impact of mount st helens volcano

loss of lives

economic impact of mount st helens volcano

cost a lot of money for repairs

environmental impact of mount st helens volcano

destroyed forests

social benefits of volcanic activity

boosts tourism

environmental benefits of volcanoes

enriches soils

economic benefits of volcanoes

short term response to natural disaster

providing shelter (natural disaster)

long term response to natural disaster

rebuilding (natural disaster)

name one place where earthquakes occur

the pacific ring of fire

describe the cause of earthquakes

movement of tectonic plates

describe how a tsunami wave occurs

underwater earthquake moves waves across water that grow taller as they reach the coastline

example of a earthquake

tohoku, japan 2011

economic impact of Tohoku earthquake

destruction of buildings

social impact of Tohoku earthquake

loss of life

environmental impact of Tohoku earthquake

groundwater contamination

short term response to Tohoku earthquake

long term response to Tohoku earthquake

rebuilding

way to lesson the impact of an earthquake

educate communities

example of a fold mountain range

the alps

economic impact of fold mountains

tourism, farming and mining

social impact of fold mountains

supports communities and cultural traditions
