<u>Iron-rich minerals align with the Earth's magnetic field</u> as basaltic lava erupts, cools, and forms magnetic patterns on the seabed.
Lava is molten rock that emerges as a liquid from under the Earth's surface. The term "lava" is also used to describe the rock that is generated when molten lava cools and solidifies. Either the substance is exceedingly stiff and barely flows, or it might be incredibly fluid, flowing nearly like syrup. The viscosity of the lava increases with silica concentration.
Hawaiian terms pahoehoe and aa (or a'a) refer to flows that are often formed by mafic (ferromagnesian, dark-colored) lavas like basalt. Smooth, subtly undulating, or extensively hummocky surfaces define Pahoehoe lava flows. A thin, still-plastic crust is dragged and wrinkled into twisted rope-like folds and rolls by the flowing molten lava beneath it.

D. Stratovolcanoes are the most common types of volcanoes in contrast to the less common shield volcanoes and include Krakatoa and Vesuvius
Explanation:
The statement that does not describe a stratovolcano is the last option.
Cindercone volcanoes are the most common types of volcanoes and are more common than stratovolcano.
A volcano is a landform that originates from magma that cools and solidifies on the surface of the earth.
- Stratovolcano are also called composite volcano.
- They are steep sided volcanoes often with water craters in this middle.
- Some of the lava cools in a stratovolcano before reaching the surface and can lead to violent eruptions.
- They are usually found along destructive margins.

B. There is no key on the map
Explanation:
Shania would be unable to determine the oldest formation because there is no key on the map. The map does not contain the proper details to be used to infer age relationships among the formations.
- A map presents a three dimensional world on two dimensional paper or surface.
- To infer relative ages, a cross section from the two dimensional representation is the most desired.
- From the cross section, the third dimension can carefully be studied and ages inferred.
- There is little to no way we can infer relative age relationship on this surface.
- To do that, we would require a key. Most times, the key shows the stratigraphic column which puts rocks in their correct ages.
- Most keys are arranged with formations from the oldest at the bottom and the youngest on top.
- Since this map lacks a key, direction, scale and other map elements, it would not be possible to infer relative ages of the rock.
