In an oil trap formed by an anticline, _____________ accumulates on top, ____________ in the middle, and ____________ at the bottom

  1. natural gas, oil, groundwater

  2. ground water, oil, natural gas

  3. oil, groundwater, natural gas

  4. oil, natural gas, ground water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In an anticline oil trap, fluids separate based on density. Natural gas is the least dense and accumulates at the top, followed by oil, and then groundwater at the bottom.

Which of the following is limiting factor in the productivity of the ocean:-

  1. NItrogen

  2. Phosphorous

  3. Magnesium

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
The amount of primary production depends on a variety of environmental factors. These factors include the availability of essential inorganic nutrients, particularly nitrogen and phosphorus; water temperature; and the turbidity of the water. Open oceans have relatively low primary productivity because of low levels of the essential nutrients nitrogen and phosphorus. So, the correct option is 'Both A and B'.
