Practice MCQ for SSC, UPSC, RRB Exams
A. Tropopause
A. ট্রপোপজ
B. Stratopause
B. স্ট্রাটোপজ
C. Mesopause
C. মেসোপজ
D. Thermopause
D. থার্মোপজ
Correct Answer: B
সঠিক উত্তর: B
Explanation
ব্যাখ্যা
The Earth's atmosphere is divided into several layers — troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
The boundary that separates the
stratosphere
from the
mesosphere
is called the
stratopause
.
At the stratopause, the temperature stops increasing with height and starts decreasing in the mesosphere.
It generally lies at an altitude of about
50 kilometers
above the Earth's surface.
