, permafrost is ground, including rock or (cryonic) soil, at or below the freezing point of water 0 °C (32 °F) for two or more years. Most permafrost is located in high latitudes (in and around the Arctic and Antarctic regions), but at lower latitudes alpine permafrost occurs at higher elevations. Ground ice is not always present, as may be in the case of non-porous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material.
A.Pangea
Pangaea is a hypothetical supercontinent that included all current land masses, believed to have been in existence before the continents broke apart during the Triassic and Jurassic Periods
The correct answer is - Eiffel.
Vulkaneifel (Volcanic Eifel) is a remnant of the volcanic past in the Eifel Mountains Range in Germany. It is very easy easy to see that this region has been shaped by volcanic activities in the past because it has lots of typically volcanic landmarks, like lava streams, craters, tuffs. This region is located between the Rhine and Wittlich Depression, and is divided into three parts, Volcanic West Eifel, Volcanic High Eifel, and Volcanic East Eifel.
The importance of Fall line is that it act as the boundary at the streams for boat traffics.
<h3>What is a Fall Line?</h3>
A fall line refers to the area where a highland region meets a coastal plain, and it is usually visible where rivers cross it, resulting in rapids or waterfalls.
The uplands are composed of relatively hard crystalline foundation rock, whilst the coastal plain is composed of softer sedimentary rock. It protects the boat trafficking by acting as the natural border.
Therefore, it can be concluded that The significance of the Fall line is that it serves as a limit at the streams for boat traffic.

Answer:
B' =( 3,-12)
Explanation:
In translation, a point K(x,y) can be translated using the rule T₁(a,b) to form K'(x+a,y+b)
The translation rule is given as T------ (2,-7)
The coordinate for B (1,-5)
Applying the translation B (1,-5) ---------T (2,-7)---------B'( 1+2, -7+-5)=(3,-12)
B' =( 3,-12)
