Question

how did the convection model show how earth’s mantle moves earth’s plates?
the water carried the pieces of paper to the middle of the container.
the water carried the pieces of paper to the sides of the container.
the water pushed the pieces of paper to the top of the container.
the water pushed the pieces of paper to the bottom of the container.

Explanation:

In a convection model simulating mantle movement, heated fluid (water here) rises, cools, and sinks, creating currents. The mantle's convection currents move tectonic plates. When simulating with water and paper (representing plates), the water's movement (convection) carries the "plates" (paper) to the sides (mimicking how mantle currents move plates towards subduction zones or spreading ridges, with sides representing plate boundaries). The other options don't align: middle isn't typical, top/bottom don't match plate movement dynamics.

Answer:

B. The water carried the pieces of paper to the sides of the container.
