Answer:
Option A, Upper areas are cooler than others
Explanation:
The relation between the latitude and climate i.e temperature is inversely proportional.
Regions located at lower latitude are actually located at a distance far away from the equator. An equator receives the highest sunlight thus a region located at a distance far away from the equator receives lower amount of sunlight due to which its temperature is a bit colder as compared to regions lying close to the equator.
Hence, option A is correct
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
The correct answer is no replacement behavior.
Answer: the core of the earth heats up the more dense part of the mantle making it less dense.<em> </em>When the less dense part of the mantle rises, the more dense part of the mantle falls, and cools off. This motion continues creating convection currents
A = (8,-3)
B = (1,8)
d = distance
