Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Most of the heat energy available on the earth surface comes from the Sun in the form of electromagnetic radiation. 
Sun is the main source of heat on the earth.
Option A
Multiple choice evs solar energy water cycle earth's energy budget solar energy and its applications

Sun loses approximately a weight of ________ every second which is the amount of ${H} _{2}$ gas that the sun turns into energy.

  1. $4$ lakh million tons
  2. $4$ million tons
  3. $4$ lakh tons
  4. $40$ lakh tons
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Sun loses approximately 4 million tons of mass every second as it converts hydrogen into helium through nuclear fusion.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Sun's rays pass through _______ to great depth.

  1. air

  2. water

  3. heat

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water,

Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). Only a small amount of light penetrates beyond this depth.

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

Heat balance is the ___________.

  1. state of equilibrium on earth between incoming insolation from venus and the outgoing terrestrial radiation from the earth.

  2. state of equilibrium on earth between incoming insolation from mars and the outgoing terrestrial radiation from the earth.

  3. state of equilibrium on earth between incoming insolation from sun and the outgoing terrestrial radiation from the earth.

  4. state of equilibrium on earth between incoming insolation from moon and the outgoing terrestrial radiation from the earth.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There is a balance of incoming solar radiation and the amount of terrestrial radiation returned to space. The balance of incoming and outgoing radiation is termed as heat balance. 

Multiple choice geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

The state of equilibrium that exists on Earth between insolation and terrestrial radiation is called ___________.

  1. insolation

  2. heat balance

  3. heat equilibrium

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Earth receives solar radiation in the form of short-wave solar radiation and the radiation is sent back to space in the form of longwave terrestrial radiation. In the absence of such a balance the earth would be getting progressively colder or progressively warmer. This balance between the amount of insolation received from the sun and outing outgoing terrestrial radiation is known as earth's heat budget or heat balance.

Multiple choice

Thermal energy from the sun and gravity are the engine of the water cycle because...

  1. Gravity allows water to evaporate

  2. The sun allows water evaporation and causes rain or snow

  3. Gravity moves the air and makes the wind

  4. Gravity allows water to go from the atmosphere to the ground
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The water cycle is driven by solar energy (causing evaporation) and gravity (causing precipitation to fall and water to flow downhill). Option D correctly identifies gravity's role in moving water from the atmosphere to the ground.

Multiple choice

Thermal energy from the sun and gravity are the engine of the water cycle because...

  1. A part of it evaporates directly or through plants (evaporation)

  2. Part evaporates another part infiltrates, another circulates through runoff

  3. Part of the water is runoff water along streams and rivers
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sun provides the energy for evaporation, while gravity drives the movement of water through infiltration and surface runoff. Option B correctly summarizes these pathways.

Multiple choice physics energy : forms and sources concept of energy energy for everything forms of energy

The energy generated in stars is because of

  1. radioactivity

  2. nuclear fission

  3. nuclear fusion

  4. photo electric phenomenon
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Energy is produced in a star's center, where pressures are enormous and temperatures reach 27 million°F (15 million°C). This causes nuclear fusion—atoms of hydrogen are ripped apart and fuse (join) to form helium. These reactions release vast amounts of energy, which makes the star shine.

Multiple choice physics spectra sunlight - white and coloured sunlight - combination of 7 lights fibre optics basics

Line spectrum is obtained from the :

  1. Sun

  2. Filament of the bulb

  3. Mercury lamp

  4. Burning coal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

As a light source, we will use a mercury lamp, which emits light at several discrete wavelengths. The device we are using is called a prism spectrometer because, once the prism is calibrated, it can be used to measure the wavelengths of the lines in the spectra produced by various atoms.

Multiple choice physics save energy types of sources of energy renewable and non-renewable resources renewable and non-renewable sources of energy

What term is known as when the solar energy fall on the Earth's atmosphere exposed perpendicularly to the rays of the Sun at the average distance between the Sun and Earth?

  1. Solar panel

  2. Solar Constant

  3. Solar Time

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

Solar constant is defined as the rate at which per unit area of the Earth's atmosphere receives the Sun's energy, when the Sun is at the mean distance from the Earth. Value is about 1388 watts per square metre.
