Video transcript

Hello everyone. And in today's video we have a very short problem. So let's jump straight into it. So which of the following does not characterize an area with low solar radiation and remember that we're looking for the incorrect or the not statement time on our answer choices. So let's begin. So it is far from the equator. If we look at how the Earth's angle works instead of in terms of just getting sun rays, sun rays are located near the equator of the earth have the greatest strength or will have the highest solar radiation while sunray is located to the end or to the poles of the earth will have the lowest because they have to travel the most, diminishing their strength. So it is actually a correct answer choice. If we look at our question, we're looking for the incorrect answer choice. So we're going to cancel this out. Moving on, we have a receives the least amount of direct sunlight. Again, if we refer to these image here, these areas located around the poles over here receive the least solar radiation or the least amount of direct sunlight. So we're going to cancel it out as well. Moving on, we have see it has a cold climate these areas since they don't receive a lot of solar radiation will have cooler climates are going to cancel this out as well because it is a correct answer choice, then we have answer choice. D it has a large annual rainfall. If you look at areas along the equator or along these areas. These are the areas that have the largest annual rainfall. This is where the tropical rainforests are usually found all areas around the poles or the areas with low solar radiation usually don't have a lot of annual rainfall. And the reason for this is because they're very dry. The low, the low solar radiation does not allow for enough vaporize a shin to take place, so there's not a lot of clouds, there's not a lot of moisture in the earth, so there's not a lot of rain. And so this is why this is the correct answer choice to our problem, and we're going to highlight it as our final answer. I really hope this video helped you, and I hope to see you on the next one.
