Weather is predicted by considering 

biology physical resources air and winds wind energy air as a natural resource

  1. The movement of air

  2. Amount of water vapour

  3. Temperature

  4. All the above

Show answer
Correct Option: D
Explanation:

Accurate weather prediction can be made only if all the air measurements i.e. temperature, humidity and wind direction are considered. 

Moving air is known as the wind which is caused by differences in air pressure. It is the air which moves from an area or high pressure to an area of low pressure and causes the day to day changes in weather. Thus the wind brings in different air masses and different weather patterns. The greater the difference in air pressure, the greater is the wind speed. 
The amount of water vapour present in the atmosphere is known as humidity. The measure of the water vapour present in the atmosphere as compared to vapour content at saturation levels is known as relative humidity. The formation of clouds and rain occurs only at 100% relative humidity and not near the surface. The rising and cooling air forms clouds and increases humidity. The fall of precipitation from the clouds occurs into layers with lower humidity. 
The measure of air's hotness and coldness is known as temperature. Temperature affects the type of precipitation that can form. If the atmospheric conditions are such that precipitation can occur and the temperature is above freezing then rain occurs. If the temperature is below freezing then, snow formation occurs. 
Thus, the correct answer is option D. 

Major component of the atmosphere on venus and mars planets is

  1. Carbon dioxide

  2. Oxygen

  3. Hydrogen

  4. Water vapours

Show answer
Correct Option: A
Explanation:
Carbon dioxide is an important gaseous component of the environment. It is fixed by the green plants by the process of photosynthesis. It is released during expiration by the process of respiration. Venus is twin planet to earth as it has atmosphere. It is the hottest planet as its is made up of 97% carbon dioxide. Mars is also a planet which has atmosphere made up of 95.5% carbon dioxide.
So, the correct answer is option A.

The average amount of CO$ _2$ in the atmosphere is

biology physical resources air and winds wind energy air as a natural resource

  1. 100 ppm

  2. 400 ppm

  3. 1000 ppm

  4. 10 ppm

Show answer
Correct Option: B
Explanation:
Carbon dioxide is an important gaseous component of the environment. It is fixed by the green plants by the process of photosynthesis. It is released during expiration by the process of respiration. As proclaimed by World Meteorological Organization, the average amount of carbon dioxide which can be passed globally by the atmosphere is 400 ppm. Increase in the carbon dioxide concentration may lead to global warming which is mainly caused due to human activities like deforestation.
So, the correct answer is option B.

Solar radiation heats up

biology physical resources air and winds wind energy air as a natural resource

  1. Land faster than the water bodies

  2. Land slower than the water bodies

  3. Both land and water equally

  4. Neither land nor water

Show answer
Correct Option: A
Explanation:

The land has compactly arranged molecules through which conduction takes place and as it is an insulator heat, the heat remains on the surface of the earth i.e. land whereas water has loosely packed molecule heat is transferred by convection and thus it takes a longer time to heat up. Also, water has a higher specific heat capacity, meaning that it requires more energy to heat water to the same temperature as a piece of land. Water also reflects more incoming radiation. The land is dark, rough, and solid, which all contribute to the absorption of the radiation. Unlike water, the land is unable to retain heat for as long as water.

So, the correct answer is 'Land faster than the water bodies'.
