Question 1

Appeared in Year: 2016

Describe in Detail Subjective▾

Differentiate between insolation and temperature and explain anomalous temperature.

Edit

Explanation

Insolation and Temperature

  • In simple words, insolation is the heat and light energy that comes from the sun on the earth՚s surface where as temperature is the measurement of the intensity of heat.
  • The sun is the primary source of energy on the earth. The earth՚s surface receives most of its energy in the form of short waves which are of electromagnet…

What is distinguishes between the evaporation and evapotranspiration?

Edit

Explanation

Evaporation and Evapotranspiration

Evaporation

Evaporation is a process by which element or compound transition from its liquid state to its gaseous.

Evapotranspiration

  • Transpiration is a process where the plant exhale their body water through leafs, stomata, in the form of vapour.
  • If evaporation and transpiration is happen together then it is called ev…

Question 3

Describe in Detail Subjective▾

Discuss the various factors of evaporation.

Edit

Explanation

Evaporation is a process by which element or compound transition from its liquid state to its gaseous. For the evaporation the water needs to absorb 540 kcal energy as latent heat at 100°c temperature.

Followings are the factors affecting the evaporation:

  • Nature of liquid: if the liquid has low boiling point and the vapor pressure is more, then the r…

Question 4

Describe in Detail Subjective▾

What is solar constant?

Edit

Explanation

  • Solar constant is the amount of solar energy receives by the earth from the sun.
  • The cause of the variation of the solar constant is for the cyclical fusion of the sun՚s atmosphere, the fusion of the sun has reduced the solar radiation and vice- versa.
  • The mean distance between sun and the earth is approximately 93 million miles, and we all know the …

Briefly explains the classification of clouds?

Edit

Explanation

Clouds is type of condensation in the upper atmosphere, based on altitude clouds are divided in to three types i) high clod ii) medium cloud iii) low cloud, based on shape clouds are divided into four categories i) cirrus ii) cumulus iii) stratus iv) nimbus.

High Cloud: (6 - 12 Km)

  • Cirrus: These clouds are formed by tiny snow particles and it is like…

Question 6

Write in Brief One Liner▾

Give geographical reasons for the following: Doldrums is a low-pressure belt.

Question 7

Describe in Detail Subjective▾

Earth՚s temperature profile

Edit

Explanation

Earth՚s Temperature Profile

The profile of earth՚s average temperature at each depth is called the geothermal gradient or geotherm. Earth՚s temperature increases from about 0°c at the surface to more than 5000°c at earth՚s center. Within earth՚s crust, temperature increases rapidly — as great as 30°c per kilometer of depth. You can experience this i…

Question 8

Appeared in Year: 2022

Describe in Detail Subjective▾

Describe how short-term variations in temperature are related to the processes of receiving energy from the sun to the Earth՚s surface and dissipating it to the atmosphere. (Paper-1)

Edit

Explanation

Over 30 percent of the solar radiations reaching the surface of the earth are reflected back to space out of which 6 percent is reflected by the surface, 17 percent is reflected by clouds and 7 percent is scattered to space. The remaining 70 percent of the solar radiation is absorbed into the earth (47 percent) and atmosphere (23 percent) . There i…

Question 9

Appeared in Year: 2023

Describe in Detail Subjective▾

How does inversion of temperature occur? Explain its significance on local weather with suitable examples. (Paper 1)

Edit

Explanation

A temperature inversion is a layer in the atmosphere in which air temperature increases with height. Temperature inversions happen when a warm layer of air traps cool air near the surface of the Earth. This condition is the inverse of what generally occurs. More often, for instance, during the day, the surface of the Earth is warm and air gets cold…
