Gateway 1: Why are some areas more prone to tectonic hazards?

Natural Hazards

Climate-related

Tectonic

Continental Theory

From Great Pangea to 7 continental plates

Evidence

Plate Tectonic Theory

Earth crust divided into 7 major plates

Plates float on semi-molten mantle and are moved by convection currents

Edges of the plates are the zones of movement and are instable as well

3 Main movements!

How the Earth was built

God made Earth in 7 days

Big Bang Theory

Internal Structure of the Earth

CORE

MANTLE

CRUST

Reason to why tectonic plates move

Convection currents

2 types of tectonic plates

Oceanic

Continental

More about CONVERGENT plates

Continental - Continental (C-C)

Continental - Oceanic (C-O)

Oceanic - Oceanic (O-O)

More about DIVERGENT plates

Result of rising magma within mantle just below the crustal plates

2 C/O plates moving away from each other

Mid-ocean ridges

forms new crust and new seafloor

Crust nearest to the ridge is the youngest

More about TRANSFORM plates

2 Plates sliding/gliding past each other

No crust destroyed/created

Earthquakes created; little or no volcanic activities
