<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:
well first they were Chinese and also they did their job horribly
Explanation:
Trees can serve a variety of purposes in the hospital such as shade for people to sit under, making the environment cool by releasing oxygen.
<h3>What is an Economic Tree?</h3>
The word economic may ring the idea of money, however, an economic tree is one that is planted to serve mankind in an array of ways.
It should be noted that the felling of economic trees is an offense under certain laws.

D its gravity so yup I just help u
The convection zone, because it shows how energy moves in a convection current
The sun can be divided into 3 major layers;
- The core
- Radiative zone
- Convection zone
Explanation:
The sun is a large sphere with diameter of approximately 1,391,000 km, about 109 times that of the earth. The core of the sun is where the fusion occurs that releases the enormous amount of energy. The core is therefore hotter than the outer shells (with exception of the corona that is hotter than the earth's surface). The convective zone is where the sun churns due to convection currents. The cooler matter on the surface always sinks towards the core, as the hotter matter from below rises to the surface. This is akin to the convection currents in the mantle of the earth.
