The amount of cloud cover in the sky is measured in _____ or ________ for meteorological purposes. 

  1. seven, oktas

  2. six, oktas

  3. eight, oktas

  4. none of these

C Correct answer
Explanation

Cover of clouds in portion of the sky visible from the observation point is known as cloud cover. Weather observer or meteorologists estimates the amount of cloud cover in sky. Cloud cover is an important factor which decides the weather of an area. The amount of cloud cover in the sky is measured in units called oktas or eight for meteorological purposes. Each okta represents one eighth of the sky covered by cloud.

Which of the following statements about Earth's atmosphere is wrong?

  1. The gaseous envelop of the earth that consists of a mixture of gases and water vapours is called atmosphere
  2. The lower level of the atmosphere up to about $7$ miles is called troposphere

  3. The middle region of the atmosphere is called stratosphere

  4. The locus of the point in space where gravity is constant is called ionosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The ionosphere is a region of the upper atmosphere ionized by solar radiation; it is not defined by the locus of points where gravity is constant.

Which of the following statements is wrong?

  1. Absolute humidity is expressed in grams per cubic metre of air
  2. 1$^o$C of temperature is reduced with every 165 metres of height

  3. When the temperature of air increases, its capacity to hold moisture decreases

  4. The higher the temperature the lower is the air pressure
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When air temperature increases, the capacity of air to hold moisture (water vapor) actually increases, not decreases. This is a fundamental principle of meteorology.

Because of the compressibility of air, more than $50$% of the mass of the atmosphere is in its _________________.

  1. Lower $3.6$ miles
  2. Below $18$ mile level
  3. Beyond $18$ mile level up to $40$ miles
  4. Beyond $40$ miles
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Due to gravity, air is most dense near the surface. More than 50% of the Earth's atmospheric mass is concentrated within the first 5-6 kilometers (roughly 3.6 miles) of altitude.
