Answer
Climate change may lead to increased flooding and extreme weather events, which disrupt communities, damage infrastructure, and exacerbate food and water scarcity. Additionally, shifts in climate patterns can impact agriculture, leading to reduced crop yields and economic instability.

Answer
Air from the Equator rises and moves towards the poles, then cools down and sinks at approximately 30 degrees 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 affecting weather patterns.

Answer
One reason for the variation in death tolls is differences in population density in affected areas; areas with higher populations are likely to experience more casualties.

Answer
At convergent plate margins, tectonic plates collide, leading to subduction, which can cause earthquakes and volcanic eruptions as one plate is forced beneath another. At divergent margins, plates move apart, creating tension that can also result in seismic activity and the formation of new crust. Transform margins involve lateral sliding, where stress accumulates until it is released as earthquakes.
