Answer: Over last few decades there is a huge increase in the amount of carbon dioxide in the environment because of various kinds of human activities.

This increase in the level of carbon dioxide has increased the temperature of the earth and has a harmful impact in ocean as it has led to acidification of water.

The amount of carbon dioxide in atmosphere was less in 1980 but has now increased from (1980) 340 ppm to (2000) 370 ppm.

Answer: A. motion parallax

Explanation:

In the phenomenon of motion parallax, objects that are moving at certain speeds across a particular field of vision, would also appear to move at greater speeds if they’re closer to the observer. This remains true even if the object instead of the person is moving

. The phenomenon always arises whether or not the object is moving or that the observer is moving in a manner that is relative to the object’s motion. This is because of the distance the object moves in comparison to the proportion of the observers’ field of view that it traverses. Thus, motion parallax generally describes one’s perception of the position of an object with a three-dimensional space, based on sensing said objects at different positions.
