HYDRAULIC fracturing, or fracking, is a drilling method used to extract petroleum (oil) or natural gas from deep in the earth. In the fracking process, cracks in and below the earth surface are opened and widened by injecting water, chemicals, and sand at high pressure. Hope this helps you.
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.
A. seafloor spreading at mid-ocean ridges
