Question

1. The main cause of natural disasters is related to... A) environmental pollution B) human activity on Earth C) global change​

Answer 1

Відповідь:

b) human activity on Earth

Answer 2

C) global change.

While both environmental pollution and human activity on Earth can contribute to natural disasters, the main cause of natural disasters is often attributed to global change. Global change refers to long-term changes in the Earth's climate system and other environmental factors, including temperature variations, sea level rise, alterations in precipitation patterns, and shifts in atmospheric conditions.

These changes are primarily driven by natural factors such as volcanic eruptions and fluctuations in solar radiation, as well as human-induced factors such as greenhouse gas emissions from burning fossil fuels, deforestation, and land-use changes. The accumulation of greenhouse gases in the atmosphere, particularly carbon dioxide, leads to the enhanced greenhouse effect, which traps heat and raises global temperatures.

The increase in global temperatures can result in various consequences that contribute to natural disasters. For example, higher temperatures can intensify weather patterns, leading to more frequent and severe storms, hurricanes, floods, and droughts. Rising sea levels, caused by the melting of glaciers and polar ice caps due to global warming, can also contribute to increased coastal erosion and the potential for more destructive storm surges.

It's important to note that while human activity plays a significant role in exacerbating natural disasters through global change, natural disasters can also occur without direct human influence, such as earthquakes, volcanic eruptions, and certain weather events like tornadoes.
