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.
The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth
Answer:
Conditions at the base of a glacier increase glacial flow velocity -
Steeper slope
Smooth rock / glacier contact
Colder basal water temperature.
Explanation:
Steeper slope and smooth rock/glacier contact will increase glacial flow velocity because higher the steepness higher the velocity and smoothness will apply less friction.
Due to decrease in ice thickness the load at the bottom of the glacier will decrease, and we know that the glacier flows under the load of itself, so lesser the load lesser the velocity.
Colder basal water temperature will generate less amount of melt as compared to warmer basal water temperature, so in colder condition, glacial flow velocity will not be increased.
