Geographic factors of Bangladesh: The main geographic factors of Bangladesh are as follows –
1. Geographic location
2. Physiography
3. Climate
4. Forest
5. Rivers
Physiography of Bangladesh : The physio-graphic condition of a country influences the socio-economic and the political situation or development of a country. Physiography of Bangladesh also influences this country .A small portion of Bangladesh is high land. Major part of our country is plain land. Though there is no plateau in our country, there are a few traces in various regions of Bangladesh.
Physiography: On the basis of the land forms, the physiography of Bangladesh is divided into three parts. Such as-
1.Mountainous region of tertiary period.
2. Traces of Pleistocene period.
3. Alluvial floodplain.
Mountainous region of Bangladesh: Hills and mountainous land is the most high land of Bangladesh, It was raised during the tertiary age. It is situated in the Northeastern, Eastern and the Southeastern part of Bangladesh. The hills and the mountains in that period are considered as the same to the Himalaya and Arakan Yoma mountain, Because these were raised at the same period.
According to the locational characteristics, this region are classified into two groups. These are as follows-
a) Northeastern Region and
b) Southeastern Region.
a) Northeastern region: The highlands in Sumangonj, Moulavibazar and the part of Netrokoana are under this region. The high land of this region are locally named as Tilla. Average height of these highlands is not more than 240 meter.
b) Southeastern region: The hills and mountains in the Chittagong, Khagrachhari, Bandarban, Rangamati are under this region. Though this area is occupied the small portion of Bangladesh, it has a great significance. Because the largest sea port of Bangladesh, the highest peak( Tagio Dong -1231m), main manmade lake and hydro electricity supply centre are situated in this region.
Traces in the Pleistocene period: the lands in Bangladesh raised in the Pleistocene period(before 25000 yrs) are under this type. Lalmai region, Modhupur trace and Barind region are the main areas of this land form in Bangladesh.
Alluvial Floodplain area: The rest of the part of Bangladesh( Without the mentioned two region) are created by rivers. Flood plains areas are given below-
i. Khulna region
ii. Greater Rangpur
iii. Lower Shylet
iv. Meghna Basin area.
That’s all about the physiography of Bangladesh.
