Urban Sprawl is pretty much the migration of a population from a populated city or town to rural land
Answer:
B. Aerobic bottom water
D. High organic productivity in the overlying oxygen rich water
Explanation:
A Shale is a sedimentary rock usually formed from silt and clay-size mineral. There are different colors of Shale. The Black Shale is formed under anaerobic conditions. This means that oxygen is deficient in the water where the Shale forms.
A little amount of organic materials is required for the formation of Black Shale and because Black Shale is formed in an environment lacking oxygen, an oxygen-rich water would not be necessary for its growth. Sediments are necessary in the formation of Black Shale.
<u>Answer:</u>
<em>D. Even though slaves were still considered property, some slaves had kind masters
</em>
<u>Explanation:</u>
According to Calhoun’s argument, the blacks were much better while serving as slaves in America than they were when they were free. This was because of racial inferiority. Since that is inferior, they are given better from the whites
Calhoun also argues that the slaves were better than free workers. This was, therefore, a common argument in the regions of the south. The slaves were better because they were treated well by their masters since the master aimed to take care of their investments.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subduction back into the earth.
