Acity is being built near a location where two continental plates meet. in designing buildings, architects of this new city should take into account which kind of possibilities?

The most important thing that the designers should take into account are the potential earthquakes - the buildings should be able to withstand the shaking of the ground.

Additionally, Earthquakes often lead to fires, so the buildings should also be fire-proof; especially not made of wood.

Finally, the possibility of a tsunami should be considered.

Ithink the answer to that would be b):

Why the planet stays in orbit is because of inertia (object stays in motion until a force changes it’s motion) also the atmosphere and gravity!
