Question

10. Think of some everyday materials that you could use to make an improved model of Earth's layers. For each layer, choose a substance whose physical properties are similar to those of that layer. Record your choices in the table below. Also record the reason that each choice is better than using clay to model the layer. (10 points)

Answer 1

Everyday materials that can be used to make an improved model of Earth's layers are dense metal objects, liquid-filled objects, playdough, and a mixture of sand and soil. These materials mimic the physical properties of the Earth's layers and provide a more accurate representation.

Step-by-step explanation:

Some everyday materials that can be used to make an improved model of Earth's layers are:

1. Inner Core: A dense metal object like a lead ball. This represents the solid iron-nickel core of the Earth.
2. Outer Core: A liquid-filled ball like a water balloon. This represents the molten outer core of the Earth.
3. Mantle: Playdough or modeling clay. This represents the thick layer of hot, solid rock beneath the Earth's crust.
4. Crust: A mixture of sand and soil. This represents the rocky surface layer of the Earth.

These materials were chosen because their physical properties, such as density and state (solid/liquid), resemble the characteristics of the corresponding layers of the Earth. They provide a more accurate representation than using clay alone.
