Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries.

Wallerstein’s world systems theory is BEST used to explain which of the following concepts?
Nady [450]

ANswer is Nationalism

World-systems theory (also known as world-systems analysis or the world-systems perspective),[1] is a multidisciplinary, macro-scale approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis.[1][2]

"World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and the periphery countries.[2]Core countries focus on higher skill, capital-intensive production, and the rest of the world focuses on low-skill, labor-intensive production and extraction of raw materials.[3] This constantly reinforces the dominance of the core countries.[3] Nonetheless, the system has dynamic characteristics, in part as a result of revolutions in transport technology, and individual states can gain or lose their core (semi-periphery, periphery) status over time.[3] This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy.[4] For a time, certain countries become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.<span>[3]</span>

vlada-n [284]

Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.

Explanation:

The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.

This is almost equal to the surface temperature of the sun which is around 5,500° C.
