<span>Distance covered by Mario in 6 hours is 330 miles.
Then, Average speed of Mario is 330 miles divided by 6 hours = 55 miles per hour
so to drive a total distance of 715 miles, it would take him ( 715 miles divided by 55 miles per hour) hours
i.e., 13 hours
so Mario will have to drive for 7 more hours to complete a total distance of 715 miles.</span>
Seafloor of the Galveston is full of sand and sediment which is suspended in and around the bay.
<u>Explanation:</u>
The water in and around the Galveston bay. The reason for the water to be brown in that area is because of the sediments and other material which are suspended to be brown in the water.
The water in the Galveston is shallow as a reason of which the sediments and the sand turn over in that area is high, making it look brown in color instead of blue. Thus water seems to be dirty and muddy at many point of time.
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:
Some, but not all, earthquakes are related to volcanoes. ... However, most earthquakes are caused by the interaction of the plates not the movement of magma . Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock.
