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

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.

In the troposphere, the temperature decreases at the rate of $1^\circ$ Celsius for every _______.

  1. 100 meters

  2. 135 meters

  3. 150 meters

  4. 165 meters

D Correct answer
Explanation

$165 meters$

Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet). The rate at which the temperature changes with altitude is called the "lapse rate".

What is the upper part of the atmosphere called?

  1. Lithosphere

  2. Exosphere

  3. Barysphere

  4. Hydrosphere
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft) where it merges into the solar wind.

Which of the following is a community of plants and animals which occupies a large geographical area within a particular climate zone?

  1. Biodiversity

  2. Biome

  3. Habituate

  4. Bog
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate.

Biosphere is existing because the interaction of ___________.

  1. lithosphere

  2. atmosphere

  3. hydrosphere

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The biosphere is the global sum of all ecosystems, representing the zone of life on Earth. It exists due to the complex interaction between the lithosphere (land), atmosphere (air), and hydrosphere (water).

 _____ is the model of the earth. 

  1. Globe

  2. Satellite

  3. Universe

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 3-dimensional model of the Earth is called globe. We cannot see the Earth all of it at once as it is so large. So, globe helps us to see what the whole Earth looks like. A globe is better representation of earth in comparison to a flat map. As the Earth spins on its axis, globe also has an axis and we can rotate it. The globe is tilted to one side because the Earth itself is tilted. So, a globe helps in properly studying the Earth.
