Multinational source of energy is

  1. Soil

  2. Water

  3. Sun

  4. All the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The sun is made up of about 80% hydrogen, 20% helium and only 0.1% other elements. 
  • Sun is the most important source of energy. The sun is the source of life on our planet Earth and, directly or indirectly, is the fuel for most renewable systems. Photovoltaic and solar thermal systems, as well as solar thermal power stations, convert solar irradiation directly into useable energy.
  • Hence Multinational source of energy is the sun.
  • So, the correct answer is 'Sun'.

Choose the correct answers from the alternatives given :
What is the source of the energy that flows through the living world?

  1. Photosynthesis

  2. Chemical bonds

  3. Sun

  4. Green plants
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sun is the ultimate and major source of energy which is required and fulfills the need of the world. photosynthesis and chemical bonds are performed and formed respectively by the sunlight due to which all the necessary reactions occur leading to the completion of all the processes. Green plants require sunlight to produce organic food in which water and gases mix with sunlight to produce their food.

So, the correct option is ' Sun'.

Who of the following are the ultimate sources of energy for carnivorous organisms in the food chain of a forest ecosystem?

  1. Sun

  2. Photosynthetic species

  3. Herbivorous species

  4. Decomposer species
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

For all organisms, the sun, or solar radiation, is the ultimate source of energy. Plants are primary producers of energy from the sun. Plants use sun, chlorophyll, water, carbon dioxide and nutrients to manufacture glucose, an alternate form of energy. 

So, the correct option is 'Sun'.

Rainfall pattern depends on

  1. The underground water table

  2. The number of water bodies in an area

  3. The density pattern of human population in an area

  4. Prevailing season in an area
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Rainfall pattern depends on the number of water bodies in an area because which area has more water bodies that area evaporates more water and this evaporation increases the precipitation water cycle and hence initiate  the rainfall 

So option 'b' the number of water bodies in an area is the correct answer.

Migration in birds is guided in part by-

  1. Celestiial navigation

  2. Temperature chnages

  3. Territorial aggression

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Birds that nest in the Northern Hemisphere tend to migrate northward in the spring to take advantage of burgeoning insect populations, budding plants and an abundance of resting locations. This is guided by celestial navigation with a sextant.

So, the correct option is 'Celestial navigation'.

Low clouds retard surface cooling at night better than clear skies because:

  1. The clouds absorb and radiate infrared energy back to earth

  2. The water droplets in the clouds reflect infrared energy back to earth

  3. The clouds start convection currents between them

  4. The clouds are better conductors of heat than is the clear night air
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Clouds act as a blanket at night by absorbing longwave infrared radiation emitted by the Earth's surface and re-radiating a portion of it back down, which reduces the rate of surface cooling.

If a glass of water were surrounded by saturated air:

  1. The level of the water in the glass would slowly decrease

  2. The water's temperature would slowly increase

  3. The level of the water in the glass would not change

  4. The water's temperature would slowly decrease
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Saturated air contains the maximum amount of water vapor possible at a given temperature, meaning there is no net evaporation or condensation occurring at the water surface. Therefore, the water level remains constant because the rate of evaporation equals the rate of condensation.

The primary source of energy for the earth's atmosphere is:

  1. Energy from within the earth

  2. The sun

  3. Erupting volcanoes

  4. Lightning discharges associated with thunderstorms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sun provides the vast majority of the energy that drives atmospheric circulation, weather patterns, and the heating of the Earth's surface and atmosphere. Other sources like geothermal or volcanic activity are negligible in comparison to solar radiation.

If you want to keep an object cool while exposed to direct sunlight,

  1. Put it inside a brown paper bag

  2. Wrap it in black paper

  3. Wrap it in aluminum foil with the shiny side facing inward

  4. Wrap it in aluminum foil with the shiny side facing outward
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aluminum foil is highly reflective. By placing the shiny side outward, it reflects the incoming solar radiation away from the object, preventing it from absorbing heat.

The lag in daily temperature refers to the time lag between the:

  1. Time of maximum solar radiation and the time of maximum temperature

  2. Time of minimum temperature and the time of maximum solar radiation

  3. Minimum and maximum temperature for a day

  4. Minimum and maximum solar energy received at the surface for a given day
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The lag in daily temperature occurs because the Earth's surface continues to receive and store heat even after the sun has passed its peak intensity at solar noon. The maximum temperature is typically reached a few hours after the maximum solar radiation.
