All the uranium in the core and mantle to decay to the point it could not keep their convection cells in motion and the core and mantle froze solid. But don't worry that will take longer than the 6 billion years we have before the sun expands to a red giant and envelops the earth, burning it up.
Nothing. We can only act to minimise the consequences of crustal plate movement (e.g. earthquakes or volcanoes) by designing and constructing earthquake resitant buildings and other infrastructure in regions likely to be effected by seismic activity as well as proper preparation for dealing with the after effects of both seismic and volcanic activity.
You do Nothing that is all you do you idiots.
the orbit
The length of a day would increase and the number days in a year would decrease.
The days would be longer
Many catastrophes could occur. Thus including Earthquakes,Tsunamis,and super Volcanic eruptions.
Yes, if two plates moved in opposite directions to each other- moving away from each other-, it could create a hole in the ground which would go on, in to the center. Also, (mainly in the ocean) by the movement of two plates moving apart a volcano could be formed underwater.
plate movement and plate tectonics
the orbit
Along plate edges is where a lot of earthquakes occur. If you were to live along a plate boundary you would be putting yourself in danger of an earthquake.
A crack in the earth's crust would more correctly be termed a discontinuity (this may also be known as a fracture or fissure). A discontinuity on which relative movement has occurred is known as a fault.
The length of a day would increase and the number days in a year would decrease.
The days would be longer
No, because if one plate is moving down then it would be underwater mountain, if the plate moved upward the it would be land mountain
Days would be shorter, and there would be more days per year. (And that was the way it used to be.)
If the movement of the plates brought all the continents together again, a single continent would form. At the moment plate movements are not heading in that direction.
Many catastrophes could occur. Thus including Earthquakes,Tsunamis,and super Volcanic eruptions.
Yes, if two plates moved in opposite directions to each other- moving away from each other-, it could create a hole in the ground which would go on, in to the center. Also, (mainly in the ocean) by the movement of two plates moving apart a volcano could be formed underwater.
The movement along plate boundaries would cause an earth quake, a tsanami, or either the building of a mountain.
