Look at the position of Location 1, Location 2, and Location 3 on the Earth's surface. Simple diagram of Earth's surface represented by a circle. There is a line labeled 'Equator' going through the circle, with 'Location 1' and 'Location 2' above the equator; 'Location 3' is below the equator. Which of these statements is most likely correct about the climate of the three locations? Location 1 and Location 3 are cooler than Location 2. Location 1 is warmer than Location 2 and Location 3. Location 2 is cooler than Location 3 but warmer than Location 1. Location 1, Location 2, and Location 3 are equally warm.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

b. climate change will cause an increase in biodiversity of all ecosystems.
