⚠you guys can you hep⚠ and i'm going to ask more question big points braniliest

1. using the model, describe how trenches and ridges form. 2. what processes drive motion of the plates?
3. what temperature and density changes occur in convection cells of a fluid or plastic material?


4. how can the mantle flow by convection if it is a solid?

1. A trench forms when one tectonic plate slides beneath another.

2. A ridge forms by rising magma in a zone where two plates are moving apart.

3. When the areas are warmed up, their density drops and they arise, then cool, sink and replicate the manner all over anew.

4. Earth's  mantle is caused by convection by currents carrying heat from the interior to the planet's surface. this is added with hot material that  cools down by conduction and convection of warmness or heat.

I hoped this helped, and if you have any questions you need to ask me comments me down below.

I hope this helps! Have a great rest of your day!
