2.) Earth Structure and Tectonic Movement

How do Convection Currents Work?

Due to the heat of the Earth's crust, warm magma rises, which lowers its density and causes it to rise. Once risen, it slides and then cools, increasing its density again and causing it to sink. When it slides, it causes the tectonic plates to move due to drag.

What is a hotspot?

A hotspot is an area of high natural disaster

What is subduction?

Subduction is the process where an oceanic crust moves under a continental plate, forming a deep, narrow trench

Describe a Destructive Boundary

The denser, Oceanic plate collides with the lighter, continental plate. The oceanic subducts, forming a narrow trench

Name an example of a Destructive Plate Boundary

Pacific Ring Of Fire

Describe a Collision Boundary

Two plates of similar density collide, yet both rise, forming tall peaks, creating volcanoes

Name an example of a Collision Boundary

Himalayas

Describe Conservative Boundary

The two plates rub together, with friction build up over time, which is released in earthquakes

Name an example of a Conservative Plate Boundary

San Andreas Fault California

Describe a Constructive Plate Boundary

The two plates pull apart, and molten rock and magma take the place, creating volcanoes and mountains

Name an example of a Constructive Plate Boundary

Mid Ocean Ridge
