Answer:
An aquatic ecosystem derives its identity from the interaction between its watery environment and the living organisms that inhabit it. The two types of aquatic ecosystems are freshwater and marine, and the maindifference is the salinity concentration. However, these ecosystems have several characteristics in common
Yes it can.
Under metamorphism,which high heat or pressure is applied to the igneous rock,the igneous rock’s chemical composition or texture will be different from that of it's parent rock and turn into a metamorphic rock.
In your case,an igneous rock would undergo metamorphism where large scale mountain building process take place such as folding and faulting,and the rock would be under very high pressure,hence turn into a foliated structure. The metamorphism is called dynamic or regional metamorphism if you want to know.
For example, an igneous rock,granite, will turn into gneiss under metamorphism in which high pressure take place.

<h2>Answer</h2>
<h3>This paper traces the history of human-environment interactions in the Pacific Islands during the last millennium, focusing on three main periods: the Little Climatic Optimum, the Little Ice Age, and, in greatest detail, the transition around A.D. 1300 between the two. The Little Climatic Optimum (approximately A.D. 750–1300) was marked by warm, rising temperatures, rising sea level and probably increasing aridity. The latter condition was linked to development of water-conservatory strategies (agricultural terracing being the most common) requiring cooperation between human groups which facilitated formation of large nucleated settlements and increased sociopolitical complexity. The transition period (approximately A.D. 1270–1475) involved rapid temperature and sea-level fall, perhaps a short-lived precipitation increase. Temperature fall stressed crops and reef organisms, sea-level fall lowered water tables and exposed reef surfaces reducing their potential as food resources for coastal dwellers. Increased precipitation washed away exposed infrastructure. Consequently food resource bases on many islands diminished abruptly across the transition. The Little Ice Age (approximately A.D. 1300–1800) was marked by cooler temperatures and lower sea levels. The lingering effects of the earlier transition largely determined human lifestyles during this period. Conflict resulted from resource depletion. Unprotected coastal settlements were abandoned in favour of fortified inland, often upland, settlements. Climate change is suggested to have been a important determinant of human cultural change during the last millennium in the Pacific Islands.</h3>

Answer:
B. charles lyell
Explanation:
He is associated with the Laws of uniformitarianism and the idea that earth is shaped by natural process operational even today and contrast catastrophism, he is considered a pioneer in climate change and shifting boundaries between oceans and continents. His publications works are on the principles of geology.
A long chain of under water volcanoes are called Seamounts.
