If you're talking about ocean currents then I think I can help. They change due to the wind, temperature and density differences.
Answer: By looking at all the age population pyramids, this would be my best guess. Every territory is different with various populations, however, to the best of my knowledge, it would be the expansive pyramid.
Explanation: Expansive population pyramids are used to describe populations that are young and growing. They are often characterized by their typical ‘pyramid’ shape, which has a broad base and narrow top. Expansive population pyramids show a larger percentage of the population in the younger age cohorts, usually with each age cohort smaller in size than the one below it. These types of populations are typically representative of developing nations, whose populations often have high fertility rates and lower than average life expectancies.
Answer:
Barrier.
Explanation:
The weather is called a barrier because it stops you from completing your task within the given time. With this weather condition, you are unable to complete your task due to unavailability of internet which is required for your task.
