Final answer:
Tia's model can show how glaciers carry soil by simulating how an ice cube (the glacier) moves over sand-covered clay and carries the sand particles with it, which is indicative of glacial erosion and transport of soil and other debris.
Step-by-step explanation:
Tia can use her model to demonstrate how glaciers carry soil by showing the movement of the ice cube over the sand-covered clay. As the ice cube, which represents the glacier, moves across the clay surface, it would pick up and push the sand particles, simulating the process of glacial erosion and sediment transport. This represents how real glaciers scrape, erode, and transport various materials including soil, sand, and rocks, eventually depositing them in new locations as the glacier melts, which affects soil development and the topography of the landscapes.
In reality, glaciers have had a significant impact on the geological landscape. They have been known to remove pre-existing soil, creating new types of soil from a mixture of different materials such as sand and clay. The movement of glaciers can also mold the earth into different shapes and create various types of topography such as slopes and valleys. The physical and chemical weathering caused by the glaciers helps to break down the crust into smaller particles, contributing to the formation of soil layers composed of gravel, sand, and clay.
