The layer of atmosphere between 10 km to 50 km above the sea level is called as:

The layer of atmosphere between 10 km to 50 km above the sea level is called as:

The mesosphere is the layer of Earth’s atmosphere between 50 kilometers and 85 kilometers above Earth’s surface. At a distance of 50 kilometers from Earth’s surface, the temperature in the mesosphere is -5^(@) Celsius, and at a distance of 80 kilometers from Earth’s surface, the temperature in the mesosphere is -80^(@) Celsius. For every additional 10 kilometers from Earth’s surface, the temperature in the mesosphere decreases by k^(@) Celsius, where k is a constant. What is the value of k ?

The angle of elevation of a stationary helicopter as seen from a point on the deck of a ship 60m above sea level,is 30^(@) and the angle of depression of its reflection in the water is 60^(@). Find the height of the helicopter above the sea-level.

The highest lake above the sea level in the world is :

An altimeter is an aneroid barometer which makes use of the change in atmospheric pressure with the change in height above the sea level (altitude). How does the atmospheric pressure change with increase in height above the sea level?

What is the lowest region of the atmosphere which extends upto a height of 10 km from sea level?
