Answer:
While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.
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.
Oceans change the land along the shore, forming tall cliffs and jagged coastlines. "The abrasive nature of seawater causes the rocks to erode over a period of time", the statement explains the type of weathering involved in this process
<u>Explanation:
</u>
The abrasive nature of the sea water of the ocean causes erosion in the rocks which are along the shore. And, this occurs for a period of time causes the formation of the tall cliffs sometimes or to the jagged coastline the other time.
The duration of erosion decides the fate of the cliff or coastline. Erosion of rocks are highly evident in ocean shore line due to the effect of salinity of the sea water. The rocks gets eroded firstly to form jagged coastline which on long exposed erosion forms cliff.
