Question

part 3: diagrams

1. create the diagram of the rock cycle. (provide a blank cycle with arrows—students fill in “igneous,” “sedimentary,” “metamorphic,” processes like “melting,” “erosion,” etc.)
2. draw & label the cross - section of earth’s layers (crust, mantle, outer core, inner core).

Explanation:

1. The rock - cycle diagram shows the transitions between igneous, sedimentary, and metamorphic rocks through processes like melting, erosion, etc. Draw a circular diagram with arrows. Label the starting point as "igneous". As igneous rocks are weathered and eroded, they form sediments which then become sedimentary rocks. Sedimentary rocks can be subjected to heat and pressure to form metamorphic rocks. Metamorphic rocks can melt to form magma which cools to become igneous rocks again.
2. For the cross - section of Earth's layers, draw a circle representing the Earth. Label the outermost thin layer as the crust. Beneath the crust, draw a thicker layer and label it as the mantle. Inside the mantle, draw two more concentric circles. The outer one is the outer core (liquid) and the innermost one is the inner core (solid).

Answer:

1. A circular rock - cycle diagram with arrows and labels: "igneous", "sedimentary", "metamorphic" and process labels like "melting", "erosion", "weathering", "compaction", "heat and pressure".
2. A cross - section of Earth's layers labeled as "crust", "mantle", "outer core", "inner core".
