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.
Answer:
Hello. You did not present the map to which this question refers, however, we can say that the earth is likely to move along the fault line.
Explanation:
Geological faults can create changes along the relief, producing mountains, escapes, depressions, among other changes. However, geological faults are not able to modify the movement of the earth and its elements, since the tectonic plates are able to move, causing the earth to move along the fault.
The tilt of Earth axis as Earth moves around the Sun
Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
- Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale.
- This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)
Earthquakes are concentrated along where there is usually large faults of concentration.
Hope this Helps!
