Explanation:
Lava Cools on the side of a volcano
Storms erode the hardened lava
Particles of hardened water settle at the bottom of lakes
Layers of sediments bond underwater
Plate movement bakes sedimentary layers.
Since the transition is from igneous to sedimentary to metamorphic rocks;
- Lava which is magma or molten rock that reaches the surface cools and solidifies to form a volcano.
- Weathering and erosion of the volcano then proceeds and sediments are formed
- The sediments are further carried underwater where they harden at bottom of lakes.
- Layers of the sediments bond and cements together underwater to form sedimentary rocks.
- Tectonic activities further bakes the layers to form metamorphic rocks.
Answer is Retrograde motion
Most of the time planet moves in expected path near the ecliptic which is east to west. Some times each planet turns around and moves to the east for a period of time, then it turns around to head in west direction again making a loop or zig-zag against the star background. This is called retrograde motion. Thus retrograde motion is the change of direction of the planets in loop.
