Answer:
Cyclones and ocean currents transport heat towards the poles
Explanation:
The reason why the tropics is not getting hotter and the poles not getting colder is due to the activities of cyclones and ocean currents which transport heats towards the poles thus enabling the temperatures at the tropics and the poles to remain fairly constant.
The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
Answer: A.Santa Ana
Explanation:
This description perfectly agrees with the Santa Ana Winds (also called Santana Winds), which are due to a meteorological phenomenon that occurs between southern California and northern Baja California during autum and early winter (although they can also occur in the other seasons of the year). In this sense, strong winds are caused by high air pressure circulating clockwise at high altitudes in the Great Basin between Sierra Nevada and the Rocky Mountains (and the Mojave Desert).
It should be noted that these winds are characteristic of the region, which dry the vegetation, knock down electric utility poles and trees, and sometimes transport hot embers, being the main cause of fire spread.
