Answer:

If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.

Explanation:

Oil spills happen when a large quantity of oil gets mixed with large water bodies like <em>sea and oceans</em>. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.

The difference between processed oil and normal oil is that they are heated at very <u>high temperatures</u> and this results in oxidation which creates <em>free radicals</em>, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.

When oil spills happen, the <em>wind</em> cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-

  • The oil gets stuck in the feathers of the birds who come by to dip themselves,
  • Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
  • The fur of animals like <u>seal and otter </u>gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
  • The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
  • Since processed oil has longer shelf life, a large quantity of animals will suffer and die.

How are convection current in the mantle and in the oceans similar? How are they different?
Vanyuwa [196]

Hello,


Convection currents in the mantle and in the ocean are similar because they both are responsible for the shaping the Earth's surface. Two forces are behind the movement of Earth's huge land masses. Those forces are convection and gravity.


Convection describes the movement of gasses or liquids due to different temperatures. The convection currents just beneath Earth's crust flow very slowly, causing movement in the plates above them. These currents are different with the fact that they produce different plate movements. Ridge push occurs from the convection currents in the ocean. These occur at mid-ocean ridges, which are elevated higher than the rest of the ocean floor. In contrary, convection causes material in the mantle to flow. Due to combined action of convection currents and gravity, Earth's plates are in constant motion.

10) List the one way plants can remove carbon from the atmosphere,
miv72 [106K]

Answer:

Forests. Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis

Explanation:

Plants are involved in the Carbon Cycle by absorbing Carbon out of the atmosphere in order to photosynthesize. The Carbon is used during the photosynthesis. It gets back in the environment by a plant's breathing process.
