Tectonic Plates
- The earth's surface is spilt up into tectonic plates
- The middle of the earth is called the Core
- Solid, made of Iron and Nickel
- Around the Core is the Mantle
- Semi-molten rock that moves slowly
- The outer layer is the crust
- Divided into slabs called tectonic plates
- Oceanic Crust, thinner
(5-10km) but more dense
- Continental Crust, thicker (30-50km),
less dense
- Oceanic Crust, thinner
(5-10km) but more dense
- Divided into slabs called tectonic plates
- Semi-molten rock that moves slowly
- Solid, made of Iron and Nickel
- Plate margins are when two plates meet
- Destructive Margins
- When two plates are moving
towards eachother
- West Coast of South
America
- When an OP meets a CP, the OP goes into the mantle as it is more dense
- Makes volcanoes and oceanic trenches
- Makes volcanoes and oceanic trenches
- If 2 CPs meet, they collide and the
ground is forced upwards to create
mountain ranges
- West Coast of South
America
- When two plates are moving
towards eachother
- Constructive Margins
- Two plates are moving away from eachother
- The Mid-Atlantic Ridge
- Magma rises to fill the gap. Small shield volcanoes and new crust
- The Mid-Atlantic Ridge
- Two plates are moving away from eachother
- Conservative Margins
- Two plates that are moving sideways past eachother
- Can be same/different direction
- Different Speeds
- Friction is made
- Earthquakes
- Earthquakes
- Can be same/different direction
- West coast of USA
- Crust is neither created or destroyed
- Two plates that are moving sideways past eachother
- Destructive Margins
