A functional region includes one central place and the surrounding areas affected by it. The functional region is organized around this central or focal point. This type of region is characterized with one common characteristic activity and with a continuous flow to and from the central hub, and the areas surrounding it.
Island arcs form only at divergent plate boundaries, whereas hotspot volcanoes form only at convergent plate boundaries./Island arcs form only at convergent plate boundaries, whereas hotspot volcanoes form only at divergent plate boundaries./Island arcs form when hot, fluid rock rises through thin spots in Earth's crust, whereas hotspot volcanoes form when two oceanic plate boundaries push against each other until subduction happens and the plates partially melt./Island arcs form when two oceanic plate boundaries push against each other until subduction happens and the plates partially melt, whereas hotspot volcanoes form when hot, fluid rock rises through thin spots in Earth's crust.
#4. Which answer choice correctly explains why this diagram shows a normal fault?
The fault plane divides two otherwise identical sections of rock./The fault plane runs from the top of the rock to the bottom of the rock at an angle greater than 45 degrees./The block of rock above the angle of the fault plane is raised above the block of rock below the angle of the fault plane./The block of rock above the angle of the fault plane has fallen beneath the block of rock below the angle of the fault plane.
#5. The Appalachian Mountains are an example of a folded mountain range. Based on this information, which of the following processes formed the Appalachians?
Melted rock called magma rose through holes in Earth's crust and gradually solidified as it cooled.
/Tectonic movement forced certain segments of Earth's crust downward and other segments upward in jagged chunks./One tectonic plate moved beneath another plate at a subduction zone, causing the rock to melt and rise above Earth's surface./Segments of Earth's crust bent and doubled over, and moving wind and water gradually shaped the rock into gently sloping domes.
B. fossil
C. event
D. stratum
Answer:
The correct answer is Secondary Waves (S).
Explanation:
When the rocks inside the earth suddenly break, or an exploration occurs, seismic waves are generated.
When an earthquake occurs, the secondary waves (S)are the second to reach a seismometer. This type of waves is known as body waves and they travel through the interior of the Earth instead of moving over the surface.
The waves that arrive first are the Primary (P) waves that are the fastest type of seismic wave, therefore they are the first to reach a seismograph.
S waves arrive second after an earthquake.
S waves are also known as secondary waves, hence why they arrive second after an earthquake.
Hope this helps!
