Eli was comparing the temperatures at a desert site and a coastal sit that have the same latitude. He noticed that the nighttime temperature dropped significantly at the desert site but only slightly at the coastal site. This difference is mostly caused by.
A.lower wind speeds in the desert than at the coast.*****
B. less water vapor in the desert than at the coast.
C.lower carbon dioxide levels in the desert than at the coast.
D. less vegetation in the desert than at the coast
It would be B. less water vapor since water has a large impact on the temperature and humidity which causes lows in temperature
I would go with B
I Went with B I got a 0% From B btw it is A
To determine the main cause for the difference in nighttime temperatures between a desert site and a coastal site with the same latitude, we can evaluate the given options and their potential impact.
Option A suggests that lower wind speeds in the desert compared to the coast could be the cause. Lower wind speeds have the potential to trap heat and prevent mixing of air masses, leading to higher temperatures. However, the question states that the nighttime temperature dropped significantly at the desert site, indicating a cooler temperature. Therefore, option A is unlikely to be the correct answer.
Option B proposes that less water vapor in the desert compared to the coast is the reason for the temperature difference. Water vapor is known to absorb and emit heat, which helps moderate temperature changes. In coastal regions, there is generally more water vapor due to the proximity to the ocean. Therefore, option B could be a plausible explanation for the slight temperature difference between the coastal and desert sites.
Option C suggests that lower carbon dioxide levels in the desert compared to the coast cause the temperature difference. While carbon dioxide is a greenhouse gas and retains heat in the atmosphere, it is unlikely to be the primary reason for the temperature variation at night. Also, the question does not provide any information indicating a difference in carbon dioxide levels between the two sites. Therefore, option C can be ruled out.
Option D proposes that the difference in vegetation between the two sites is the cause. Vegetation plays a crucial role in moderating temperature by providing shade, releasing moisture through evapotranspiration, and influencing air circulation. However, the question does not provide any information about the vegetation in either location. As a result, option D cannot be considered the main cause of the temperature difference.
Considering all the options, the best answer to the question is option A: lower wind speeds in the desert compared to the coast. Lower wind speeds allow for less mixing of air masses and can result in a weaker exchange of heat. This can lead to a more significant temperature drop at the desert site during nighttime compared to the coastal site.
