Answer:
A. The astenosphere is denser than the lithosphere
Explanation:
The theory of isostasy is a theory that suggest that the layers of Earth are arranged in accordance to their density. It is a theory that usually refers to the mantle and crust. The mantle (astenosphere) is denser than the crust (lithosphere), so the crust floats on top of it, depending on its density, with he continental crust being higher, while the oceanic crust being lower. The two forces that are responsible for this are the gravity and buoyancy.
Europe and America used slaves for labor so the slaves in America or Europe are subtracted from the South African population.
The movement of the plates makes the oceans waters move very roughly and fast
Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content. Such a flow would have a high viscosity<span> (a high resistance to flow). A basalt flow like those in Hawai'i have low silica contents and low viscosities so they can flow long distances. Such a flow can move as far away as 4 km from its source and have a thickness of 10 m (Bryant, 1991). These flows can move at rates of several kilometers per hour (Scott, 1989). </span><span>More silica-rich flows can move as far away as 1.3 km from their sources and have thicknesses of 100 m (Bryant, 1991). These flows can move at rates of a few to hundreds of meters per hour (Scott, 1989). If a lava flow is channelized or travels underground in a lava tube then the distance it travels is greatly extended.</span>
