PRACTICES The Cycling of Matter through Thermal Convection Minor3 One of the challenges scientists face is how to understand things they can't see For this activity, you will research how geoscientists investigate Earth's structure. Then, you will develop model(s) that describe how matter is cycled in Earth's Interior by thermal convection. You will need a one-dimensional model of changes in density within Earth and a three dimensional model to show the relationship between thermal convection and place tectonics.

## Step 1<br />The first step in this activity is to describe the process or question that the model will illustrate. This involves understanding the topic of thermal convection and its role in the cycling of matter through the Earth's interior. The model should aim to demonstrate how thermal convection contributes to plate tectonics and the cycling of matter within the Earth.<br /><br />## Step 2<br />The second step involves choosing the type of model and the materials needed to develop it. The model can be either physical or digital, depending on the resources available. For a physical model, materials such as clay, a heat source, and a container could be used. For a digital model, software that allows for 3D modeling and animation would be necessary.<br /><br />## Step 3<br />The third step is to sketch a prototype of the model. This involves creating a basic outline of the model that will be developed. This step is crucial as it helps in visualizing the model and planning its development.<br /><br />## Step 4<br />The final step is to complete the model and explain how it works. This involves detailing how the model demonstrates the process of thermal convection and its impact on plate tectonics. The model should clearly show the movement of matter due to changes in density caused by heating and cooling, and how this movement leads to the formation of tectonic plates.
