Which layer experiences temperature increase with altitude due to ozone absorption?
ওজোন শোষণের কারণে কোন স্তরে উচ্চতার সাথে তাপমাত্রা বৃদ্ধি পায়?
Practice MCQ for SSC, UPSC, RRB Exams
A. Stratosphere
A. স্ট্র্যাটোস্ফিয়ার
B. Troposphere
B. ট্রোপোস্ফিয়ার
C. Mesosphere
C. মেসোস্ফিয়ার
D. Exosphere
D. এক্সোস্ফিয়ার
Correct Answer: A
সঠিক উত্তর: A
Explanation
ব্যাখ্যা
The
stratosphere
lies above the troposphere and extends roughly from
10 km to 50 km
above Earth’s surface.
This layer contains the
ozone layer
, which plays a crucial role in absorbing
ultraviolet (UV) radiation
from the Sun.
When ozone absorbs UV radiation, it converts the energy into heat, causing the
temperature to increase with altitude
.
In contrast, in the
troposphere
, temperature decreases with altitude.
The
mesosphere
again experiences decreasing temperature with height.
The
exosphere
has extremely thin air and does not show this ozone-related temperature pattern.
স্ট্র্যাটোস্ফিয়ার
স্তরটি ট্রোপোস্ফিয়ারের উপরে অবস্থিত এবং এটি প্রায়
১০ কিমি থেকে ৫০ কিমি
পর্যন্ত বিস্তৃত।
এই স্তরে
ওজোন স্তর
বিদ্যমান, যা সূর্যের
অতিবেগুনি (UV) রশ্মি
শোষণ করে।
ওজোন যখন UV রশ্মি শোষণ করে, তখন তা তাপে রূপান্তরিত হয়, ফলে
উচ্চতার সাথে তাপমাত্রা বৃদ্ধি পায়
।
অন্যদিকে,
ট্রোপোস্ফিয়ার
স্তরে উচ্চতার সাথে তাপমাত্রা হ্রাস পায়।
মেসোস্ফিয়ার
স্তরেও উচ্চতার সাথে তাপমাত্রা কমে।
এক্সোস্ফিয়ার
স্তরের বায়ু অত্যন্ত পাতলা এবং এখানে ওজোনজনিত তাপমাত্রা বৃদ্ধির প্রভাব দেখা যায় না।
