List-I	List-II
(a) $10\text{km}$ height over earth's surface	(i) Thermosphere
(b) $70\text{km}$ height over earth's surface	(ii) Mesosphere
(c) $180\text{km}$ height over earth's surface	(iii) stratosphere
(d) $270\text{km}$ height over earth's surface	(iv) Troposphere

• A. $\left(a\right)-\left(ii\right),\left(b\right)-\left(i\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(iii\right)$
• B. $\left(a\right)-\left(iv\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(i\right)$
• C. $\left(a\right)-\left(iii\right),\left(b\right)-\left(ii\right),\left(c\right)-\left(i\right),\left(d\right)-\left(iv\right)$
• D. $\left(a\right)-\left(i\right),\left(b\right)-\left(iv\right),\left(c\right)-\left(iii\right),\left(d\right)-\left(ii\right)$

Answer 1

The correct option is B $\left(a\right)-\left(iv\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(i\right)$

Troposphere: The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high.

Stratosphere: The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.

Mesosphere: The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high.

Thermosphere: The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high.

Ionosphere: The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 km (600 mi).
