Question

THE ROCK CYCLE AND PLATE TECTONICS The diagram below indicated by a dashed line. shows a cross section of the Earth's tectonic plates. The ocean surfoce is A B 1. In the boxes near the bottom of the diagram, label the two plate boundaries "Convergent 2. Put arrows on either side of each plate boundary showing the direction each plate is 3. On the letters on the cross section above, label a place where each of the rocks listed below with subduction," and "Divergent." moving forms (some letters will be used more than once and others will not be used): basalt granite and diorite andesite and rhyolite shale limestone sandstone slate and schist 4. On the line above each column of rocks in Question 3, label the rock type as igneous metamorphic, or sedimentary 5. Two students are discussing where metamorphic rocks are formed. Student 1: The convergent boundary is where the ocean plate is moving toward the continental plate, so the metamorphic rocks form at B Student 2:I think they form at F because they both appear to be made out of sand-type sediments, and F is located on a beach. With which student do you agree? Why? divergent convergent transform no plate b divergent convergent transform no plateb 6. In which locationls) might each rock type ypically orm in terms of tectonic plate boundaries? Igneous: nvergent transformno plate

Explanation / Answer

1. The box to the left- Convergent boundary (two plates move towards each other)

The box to the right - Divergent boundary ( the plates move away from each other)

2. According to the movement of plates,

Arrow for convergent boundary ----> <----

Arrow for Divergent boundary <--- ---->

3. A: Igneous rocks (Andesite and Rhyolite)

B: Metamorphic rocks( slate and schist) and Igneous rocks (granite and diorite)

C: Sedimentary rocks ( shale, limestone and sandstone)

D: Basalt(MORB)

4. Basalt , Granite, Diorite, Andesite and Rhyolite- Igneous rocks(formed by cooling of magma )

Shale, Limestone and Sandstone - Sedimentary rocks(formed by deposition and cementation of materials )

Slate and Schist - Metamorphic rocks (formed by transformation of igneous, sedimentary and metamorphic rocks)
