The correct answers are:
2. Fresh water is essential to all life on earth.
and
4. Most of earth's water is stored in the oceans
Answer: Very Likely
Explanation:
Michigan has had 24 deaths from extreme cold in the last 20 years.
This is a rate of:
= 24 / 20
= 1.2 deaths per year.
For something to be considered ''very likely'' to occur, the chances of that thing occurring needs to be above 90%.
Going by the deaths per year, the probability is more than 90% at 120%. It is therefore very likely that there will be a death from extreme cold.
Answer: a crack forms in the oceanic crust
Explanation:
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.
