The topography of Bangladesh is frequently altered due to floods.
<u>Explanation</u>:
- Even though Bangladesh is a small country, it has considerable topographic diversity.
- It has three prominent features - a large alluvial plain subject to frequent flooding, a slightly elevated relatively older plain and a small hill region drained by flashy rivers.
- Bangladesh experiences heavy monsoon rains, especially over the highlands.
- Causes of flooding in Bangladesh include -
i. monsoon climate which brings heavy rains.
ii. spring snow-melt which results in soil erosion and a rapid increase in river discharge.
ii. deforestation in head water areas due to increasing population in Nepal and Tibet.
iv. rivers slit-up due to increased soil erosion which raises river beds and lowers the capacity of the channel resulting in floods.
Answer:
Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening low-lying islands and coastal cities.
Answer:
Carbon dioxide from volcanic activity became a major part of the atmosphere.
Explanation:
It is true. Changes in rainfall and other forms of precipitation are one of the most most critical factors determining the overall impact of climate change. Rainfall is much more difficult to predict than temperature but. Seasonal projections of both temperature variables reflect lower robustness and suggest a higher future increase in winter temperatures than in other seasons.
