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:
19.68
Explanation:
Given:
Vertices : (-5,2), (3,2), (1,6)
To get the length of each side, we need to
Length = √(x2 - x1)^2 + (y2 - y1)^2
calculate the distance between the points ;
Taking, (-5,2), (3,2)
L1 = √(3 -(-5))^2+ (2 -2)^2
L1 =√(3 + 5)^2 + 0^2
L1 = √8^2 = √64 = 8
Taking L2 ; (3,2), (1,6)
L2 = √(1 -3)^2 + (6 - 2)^2
L2 = √ (-2)^2 + 4^2
L2 = √ 4 + 16
L2 = √20 = 4.47
Taking L3 ; (-5,2), (1,6)
L3 = √(1 - (-5))^2 + (6 - 2)^2
L3 = √(1 + 5)^2 + (6 - 2)^2
L3 = √6^2 + 4^2
L3 = √36 + 16 = √52
L3 = 7.21
Therefore, perimeter = L1 + L2 + L3
8 + 4.47 + 7.21 = 19.68

See it in the explanation
Explanation:
1) Carbon moves from atmosphere to hydrosphere and biosphere in the process of photosynthesis and to lithosphere by deposition of dead bodies while from hydrosphere and biosphere, carbon can be move in the process of respiration by animals.
2) During respiration process which takes place in plants in which carbondioxide is released and by eating carbon containing food by animals. By decomposing the food, carbon is releases in the form of carbondioxide.
3) Carbon can be used by the marine plants in the process of photosynthesis and during the process of diffusion, carbon is also dissolve in water bodies.
4) When the plants and animals die, the carbon which is present inside their body is buried in the soil present at the bottom of the ocean and the shells and corels of some animals also contain carbon which is soon be the part of the lithosphere when they die.
5) After the decomposition of seashell, carbondioxide is produced because shells are made up of calcium carbonate.
