=Plate Tectonics=

There are alot of steps to my cycle. Convection, heat, and gravity are the forces in my cycle
====Convection is in my cycle when the mantle is heated the rock particles in the mantle condense and fall and that is when the gravity comes in the gravity pulls the rock particles down towards the core and the heat particles expand and rise into the air**.** When the heat particles heat up the mantle gets heated up and then it expands and rises.====

Plate Tectonics can affect humans. Humans affect plate tectonics too. Because people when they do construction work and since the outer layer is our crust they are drilling into our crust.
====Plate tectonics has a huge impact on humans because when the plates get heated sometimes one plate will go on top of the other and it could cause an earthquake or a volcano and it impacts on humans because when earthquakes happen alot of peoples houses get destroyed and and people get injured or even most of the times get killed and when volcano's happen it impacts on humans because it explodes hot magma\ lava, and people get killed because it is so boiling hot.==== ====My cycle is important because plate tectonics causes earthquakes and volcano's and they are dangerous and because not only do they damage things these plates moved our continents around and that is why plate tectonics is a very important cycle.====
