The correct answer is - 1,180 km.
North America and Europe move away from one another, though on the other end of the plates, the Eurasian and the North American plates are actually merging. 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
Then 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.
Answer:
e) a drive
Explanation:
We felt thirsty when we have fluid imbalance in our body either we have less water or we have more concentration of osmolytes such as sodium in blood. The brain detect the change produce the effect for the intake of water.
- However thirst is a vital primordial emotion that motivates us for fluid intake. So the emotion produces a drive to quench it.
- Some recent studies refers it as basic instinct to drink water.
