Answer and Explanation:
Pangaea is the term used to describe the supercontinent that existed millions of years ago, before the continents were spread across the globe as we know it today. The separation of continents occurs due to the rapid convections of the Earth's mantle. These mantle convections increased volcanic activity on the earth, making volcanism very active and causing numerous volcanic eruptions, which increased the concentration of carbon dioxide in the atmosphere, increasing the greenhouse effect and creating a long period of intense global warming.
It was this global warming that altered the evolutionary events on earth, promoting a strong natural selection of plants and animals, which even led to the creation of new species and extinction of old species, in addition to creating a geographical and environmental modification.
La Soufriere Hills volcano is a group of active volcanoes. The volcanic eruptions altered the climatic conditions and led to natural selection.
What is Pangaea?Pangaea was used to describe the supercontinent that existed millions of years ago before the separation of the continents present now. The rapid convections in the mantle of the Earth caused the shift and drift in the tectonic plates.
The movement of the tectonic resulted in increased volcanic activities that caused numerous volcanic outbreaks resulting in increased carbon dioxide concentration in the environment.
This led to global warming and resulted in a change in climatic conditions. Global warming altered the evolution of the organisms through the process of natural selection and led to the extinction and the introduction of species.
Therefore, volcanic eruptions and Pangaea resulted in environmental and geographical alterations.

The correct answer is D. Assigning representatives to control different provinces.
Explanation
Chandragupta Maurya was a Maurya leader who managed to unify much of the territory of the Indian subcontinent. During his mandate, he defeated several Greek armies motivated by the conquest of new territories in Asia. In addition, he meant an improvement in economic activities, internal and external trade, and agriculture. In the administrative aspect, he stood out for delegating governance responsibilities to representatives who controlled different provinces to provide security to the population because the size of the Empire's territory prevented him from governing from a center of power, so he had to delegate powers to avoid weakness throughout the territory. Therefore, the correct answer is D. Assigning representatives to control different provinces.
What kind of landform is found in
a divergent boundary at the
bottom of the ocean?
Answer:
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
