The answer is D. The Palaeozoic era was characterized by the supercontinent of Pannotia which was located at the current position where Chile is, 500 million years ago. There is evidence that shows that central Africa was once at the polar regions due to evidence of glaciers in its geological rocks. Due to tectonic movement, the Appalachians and the Ural Mountains were formed in the resulting Pangea supercontinent.
Answer:
The North European Plain.
Explanation:
A physical region that is known for being the most productive agricultural lands in Europe is the North European Plain which exists mostly in Denmark, Poland, Belgium, Germany, the Netherlands, with little parts of northern France and the Czech republic. As the main use of the Northern European Plain is commercial farming, with few natural vegetation remaining, while the region also covers heath, bogs, and lakes.

Explanation:
Italian astronomer Galileo Galilei discovered four of Jupiter's moons , in year 1610 . Now these are known as Io, Europa, Ganymede, and Callisto. Io is innermost of these four moons and one of the most volcanically active planetary object still discovered. These moons are very much different from any other planetary body in every respect. The Voyager spacecraft pictures show that the surface of the moon io is completely covered by volcanoes and lavas rather being covered by pitts and craters. this gives the surface a very young look. The main cause of the intense volcanic activity found out here is the strong gravitational force created at the center of the moon from the Jupiter and Europa. Due to the synchronous rotation with Jupiter, solid materials at the surface of io bulges up just like the tidal motions of the oceanic water in the case of Earth. This repeated bulging causes the materials to get hitted up in a manner similar to repeatedly stretching and smashing a clay ball or rubber band. This enormous amount of heat generated in the process melts rock materials at depth and results in widespread volcanisms.
Hypotheses to explain different levels of volcanism:
a) This is very much evident that the volcanic activity is largely driven by the gravitational forces of the Jupiter. If the moons are at different distances from the large planet then the gravitational pull will be also varying for the moons and this will cause differential amount and types of volcanic activity at the moon's surface.
b) In case of io, the moon is largely made up of iron and iron sulphide core and a silicate outer surface. This silicate outer surface of the moon melts down to create the widespread volcanic activity. In case of Europa the outer surface is made up of vast quantity of water and ice. So there is lesser chance of volcanic activity in this moon. So the volcanic activity is greatly controlled by the lithological composition of the moon.
c) There is a vast amount of sulphur present at the interior of io which gets degassed and comes to the surface to create the fierce nature of the volcanisms. These gases are essential for a violent volcanism, and controls the nature and level of volcanism.
Rainstorms provide natural moisture to the environment. Receiving rain will keep plant life healthy, give animals a natural reservoir to drink from, as well as keeping the life in the river healthy. Though a flash flood may cause damage to buildings and habitats at first, buildings can be fixed and over time, wild flora and fauna will return to the area, often more plentiful, is there is a good amount of moisture <span />
