Which of the following statements is correct with respect to incoming solar radiation? I. The surface of ocean water receives more insolation than the surface of land. II. A land surface loses heat very quickly through outgoing terrestrial radiation.

Which of the following statements is correct with respect to incoming solar radiation? I. The surface of ocean water receives more insolation than the surface of land. II. A land surface loses heat very quickly through outgoing terrestrial radiation. Correct Answer Only II

Incoming solar energy in the form of short wave radiation that reaches the Earth is called Insolation.  Important Points

  • Some insolation is absorbed by the earth, which is then radiated back into space via terrestrial radiation.
  • The amount of insolation received on the earth's surface is not uniform. It varies based on the time and place.
  • The equator receives less solar radiation than the tropics.
  • The higher heat capacity of the land is the reason why outgoing terrestrial radiation rapidly loses heat from a ground surface.  

Additional Information

  • In general, the continent receives greater insolation (land has higher specific heat capacity than water bodies) than the oceans at the same latitude.

Hence, only statement II  is correct with respect to incoming solar radiation.

In the question given below,three paragraphs are given, which arejumbled. Find the correct sequence ofthese paragraphs so that they form ameaningful passage.
A. Climate change is warming the ocean,but its warming land faster and thatsreally bad news for air quality all overthe world, says a new University ofCalifornia, Riverside study. The study,published February 4 in Nature ClimateChange, shows that the contrast inwarming between the continents andsea, called the land-sea warmingcontrast, drives an increasedconcentration of aerosols in theatmosphere that cause airpollution. Aerosols affect the climatesystem, including disturbances to thewater cycle, as well as human health.They also cause smog and other kinds ofair pollution that can lead to healthproblems for people, animals, andplants.
B. To determine this, the researchersran simulations of climate change undertwo scenarios. The first assumed abusiness-as-usual warming model, inwhich warming proceeds at a constant,upward rate. The second model probeda scenario in which the land warmed lessthan expected. In the business-as-usualscenario, enhanced land warmingincreased continental aridity and,subsequently, the concentration ofaerosols that leads to more air pollution.
C. A robust response to an increase ingreenhouse gases is that the land isgoing to warm faster than the ocean.This enhanced land warming is alsoassociated with increased continental
aridity. The increase in aridity leads todecreased low cloud cover and less rain,which is the main way that aerosols areremoved from the atmosphere.
Heat gain through insolation and heat loss through terrestrial radiation are equal approximately at which latitude?
With regard to greenhouse gases, which of the following statement(s) is true? 1. The primary greenhouse gases of concern today are Carbon dioxide and chloro-fluorocarbons, which absorb terrestrial radiation when it is present in the upper troposphere. 2. Ozone which absorbs ultraviolet radiation in the stratosphere is very effective in absorbing terrestrial radiation when it is present in the upper troposphere. 
P, Q, R, Sand T are five crops that Babu grows. T is fast growing and more water demanding than R which gives more yield than T. P gives more yield than R and grows faster than Q. Q is more water demanding than T but is second lowest yielder, S is the slowest growing and least water demanding of all crops but gives highest yield. R is more water demanding and grows faster than P. Select the crop or crops that has/ have as many as crops that are more water demanding and as many as crops that give less yield than it.
