Lab: Plate Boundaries and Movement

Question 1

Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Fill in the terms that complete the statements. In this lab, you modeled how plates move. The plates that make up Earth’s lithosphere move because of . You also saw how plates interact with each other. The interactions between plates form plate of which there are three main types.

A: convection

C: Earth's plates

Question 3

How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?

Revolt · Accepted Answer

In the cool water, the food coloring stayed at the bottom of the container with very little movement. In the heated water, the food coloring rose to the top, spread to the sides, and then sank back down. This difference is caused by convection currents; the heat source makes the water at the bottom less dense, causing it to rise, while the cooler, denser water at the top sinks.

Question 4

How did the convection model show how Earth’s mantle moves Earth’s plates?
