Answer:
option (c) 14.7 lbs
Explanation:
Data provided in the question:
Area of the column = 1 square inch
Now,
we know Air pressure at the ground surface level from the atmosphere
= 14.7 Psi
also, it can be represented as
14.7 Psi = 14.7 pounds per square inch
Therefore,
Weight of the air weigh within a column that is 1 square inch in area
= Air pressure × Area
= 14.7 pounds per square inch × 1 square inch
= 14.7 pounds i.e 14.7 lbs
Hence,
The answer is option (c) 14.7 lbs
The main mechanism through which the layering happened is gravity: it pulled the heavier, denser material to the center, leaving the less dense material on the surface.
The material that was on the outside cooled quicker, but this was the result, not the cause.
The answer is
<span>2) Gravity caused more-dense material to move toward the center of each planet.</span>

Explanation:
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.
