Oil workers activities involved in the exploration of crude oil and natural gas creates pollution which affects the ecosystem negatively. The various pollutions cause the death of plant and animal life both on land and in water bodies.

The oil workers should be more careful in their activities to prevent oil spillage as much as possible and if there is any at all then there should be adequate measures in the cleaning it up efficiently through biological and harmless chemicals.

Suppose the North American plate is moving away from the Eurasian plate at a rate of 2 cm per year. The eastern-most point of No

Archy [21]

The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
