tectonic plates keyterms

an irregularly shaped huge slab of solid rock that is moving in different directions

a soft and fluid layer found below the lithosphere where tectonic plates lie

a supercontinent that existed about 200 million years ago​ (a)  

• pangaea
• gondwana
• laurasia
• paleozoic

the gradual movement of the continents where they began to break into pieces and move away from each other about 200 million years ago​ (a)  

• continental drift
• oceanic convergence
• tectonic stability
• landmass fusion

the process of mountain formation ​ (a)  

• orogeny
• volcanism
• erosion
• sedimentation

the most stable and oldest part of the continental crust. These are found deep in the interior of most continents and are composed of ancient crystalline basement rock​ (a)  

• craton
• mantle
• sedimentary basin
• oceanic ridge

an area on earth where tectonic plates collide with each other

• convergent plate boundaries

• heat transfer

• pangaea

Regions where two tectonic plates meet, and one plate is pushed beneath the other. The continental crust is typically 30-50 km thick & made up of minerals such as silicon and aluminum.​ (a)  

• subduction zones
• mountain ranges
• oceanic ridges
• fault lines

when energy moves from warmer object to a cooler object

• heat transfer

• convection

• radiation

The transfer of energy through empty space, where there is no direct contact between a heat source and an object. An example is the heating of the Earth from the sun.

• conduction
