Plate tectonics
By Elijah Smith
Explanation of how convection currents cause plate motion and continental drift.
If you have a warm liquid moving up and over it's going to constantly shift those plates outward. Since there are plates next to it it is going to push those too.
Plate Motion at all 4 types of plate boundaries.
One plate boundary is divergent, and this is when two plates move away from each other creating earthquakes and magma rises and this forms a volcano. Another plate is convergent, and convergent is when two plates move forward causing an earthquake and a mountain range. The 3rd one is the subduction zone is when the oceanic crust goes down and continental crust goes up. This also makes an earthquake. The last one is transform, transform is when two plates are side by side and the make something like friction and this makes earthquake.
A description of convection currents.
Convection currents happen when the mantle comes in contact with the outer core, it is going to heat up. The hot liquid will rise because it is now less dense. As the mantle rises towards the crust, which is going to want to shift over and cool down. Generally this cycle will restart over again.
Convection currents
Convection currents are made when the outer core touches the mantle and hot liquid will rise and it moves plates and it will continue to rise and when it goes to the crust it cools and it shifts over the cycle will continue.
All plate movements
One of the plate movements is Convergent and there are two types of convergent boundaries. One is subduction zone and that's when one plate is more dense than each other and then the one that is more dense sinks under the less dense one. The second one is when two plates are the same density and they combine and make a mountain range. The second plate movement is divergent and that's when
An explanation on how convection currents cause plate movement and continental drift.
Convection currents cause continental drift and plate motion because the way they're moving. On the picture you see three circles provided with arrows those are convection current movements and as you see two continents are moving towards each other, because of the convection currents are rotating towards each other.
