Option: a. 200 million years ago
Explanation:
Million years ago, Earth had one supercontinent called Pangaea and surrounded by an ocean (Panthalassa). Alfred Wegener proposed the concept of one big continent after putting together different records of confirmation. He was able to give his theory by examining fossils of plants, trees, animals, and reptiles that found in different continents. About 200 million years ago, the supercontinent began to split up into two parts; Gondwana from Laurasia. Today's countries, including Africa, Antarctica, India, South America, and Australia are part of Gondwana, where Europe and North America from Laurasia.
<span>Fossils usually only form in sedimentary rock. Sediments have to accumulate over the organism in order to preserve it. This could be a rapid burial, such as a volcanic eruption or mudslide, it could be sap from a tree oozing over an insect, or simply a slow sediment accumulation on the bottom of a lake.</span>
Answer:
Relic Border
Explanation:
A physical border is a naturally occurring barrier between two areas
(rivers, mountain ranges, oceans, and deserts)
An antecedent border is a boundary that already existed before the present settlement in that area occurred (the 49th parallel separating the US and Canada)
A relic border is a boundary that has ceased to function but can still be detected on the cultural landscape. <em><u>It no longer exists as an international boundary </u></em>(the Berlin Wall separating East and West Berlin)
A superimposed border is a boundary impose on an area by a conquering or colonizing power that ignores existing cultural landscapes (the division of African countries by the British)
A geometric border is a boundaries drawn based on a grid
system (line of latitude or longitude)
