Answer
The correct answer is D. Volcanic activity. This is considered a natural factor because volcanic eruptions can release large amounts of ash and gases into the atmosphere, which can influence climate patterns.

Answer
The correct statement is B. The sea ice reached its smallest extent in 2012. This indicates the significant impact of warming patterns on Arctic sea ice.

Answer
Climate change can lead to severe weather events, impacting agriculture, leading to food shortages. It may also cause rising sea levels, displacing communities and leading to loss of homes.

Answer
Air from the Equator rises and moves towards the poles, then cools down and sinks at approximately 30° north and south of the Equator. The sinking air creates an area of high pressure with very little rainfall. Some of the air moves back to the Equator as surface winds which drive weather patterns.

Answer
The correct statement is A. Between the Tropics. Tropical storms typically form in the tropical regions where there is warm water to fuel them.

Answer
To calculate the median, arrange the number of deaths in ascending order and find the middle value, which is 11,490.
Step 9

Answer
One reason is the level of preparedness and infrastructure in affected areas. Regions with better disaster response systems and early warning mechanisms typically experience fewer fatalities.

Answer
At divergent plate margins, tectonic plates move apart, leading to volcanic activity as magma rises to fill the gap, creating new crust. At convergent margins, one plate subducts beneath another, resulting in earthquakes due to the immense pressure and friction, potentially leading to volcanic eruptions as well.
