What is meant by meridional circulation in the atmosphere?
Tamiku [17]

The correct answer is D. Air moving along lines of constant longitude

Explanation:

In geography, the word meridian refers to an imaginary line that connects the North pole and the South pole, this includes the main meridian called Prime Meridian as well as multiple longitude lines that determine East and West.

On the other hand, the meridional circulation refers to a natural phenomenon in which air and air masses move from North to South and vice-versa following longitude lines or the imaginary lines that divide the planet vertically. Additionally, the meridional circulation affects climate especially in terms of extreme weather. According to this, the meridional circulation means "Air moving along lines of constant longitude".

melamori03 [73]

Answer:

B. Aerobic bottom water

D. High organic productivity in the overlying oxygen rich water

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.
